Well Pump Breaker tripped & chatters when tried to click it on


Hi All,

Wasn't sure whether to put this in electrical or plumbing, but since I didn't see anything about water pumps, I figured I'd run it by you guys.

I have a 3/4HP well pump, less than 10 years old, which has worked flawlessly until the past month or so. The problem is that it trips a breaker now and then. No rhyme or reason as to why/when, though. It does this maybe once a day, maybe two times and maybe not at all .

The double breaker (can't tell exactly if it's a 30 or 40) is very hard to turn totally off and back on after it trips. My first idea is to change that sucker. I've never had one go out before, but I guess it does happen. Maybe they weaken over time, no? The house is less than 10 years old.

One other thing: The pressure is turned up to about 90. That may be too much, but when I tried to adjust it downward, the "switches" (points?) don't want to work properly. I must say that I don't understand all I know about that little box, though...

Hello, my pump is only maybe 2 years old, and it's been fine until recently. Here's the chain of events.

A few months ago, I removed a pool mesh fence I've had for years, because we don't need it anymore. An unforeseen consequence is that more debris blows into the pool now.

I have been neglecting changing out the basket filter next to the pump more than I should have. With the increased debris, this neglect was as more serious matter than usual. One day I noticed the water pressure coming out of the jets was remarkably low. At first I thought: I need to backwash. I did so, and even during the backwashing the pressure was low.

My next thought was: the sand in my sand filter is 5 years old, so I'm due to change it out. I figured it was old sand. My local pool store (Leslie's Pool Supply) agreed, and said the sand was definitely the problem. So they sold me 300 pounds of sand, and I changed out my sand (doing the work myself).

Then I go to open the lid over...

need a little more info on it if you have it
what is it doing , does it run for a while then trip the cb or does it trip the cb as soon as you reset it
how many wires go down the "hole" ?
pump horsepower ?
what about the overload on the bottom of the cap box ?
do you have a "pumpsaver" ?
voltage ?
in my exp with well pumps if they have a above ground box and have 4 wires going down the hole , your start and run caps are in the box

i just replaced my deep well pump (400 feet) the overload on the bottom of the cap box was tripping out once or twice a week
turned out the problem was sand , it had got in the pump and wore on the plastic impeller rings and the whole stack had shrunk in lenght and created alot of extra drag that overloaded the motor

usually the caps are fairly hardy in the franklin stuff , they worst ive seen with them is they start to leak and grow some nasty stuff on the terminal
i have also replaced...

Find the main circuit breaker box. Some homes may have 1 large main breaker box as well as smaller branch breaker boxes.


Locate the defective breaker.

A tripped breaker is halfway between the on and off position.

Before assuming a circuit breaker needs to be replaced, try resetting the breaker by turning off all lights and unplugging all devices on that circuit. Then turn the back to the on position. Some breakers must be turned all the way off before they can be turned back on. Test the circuit breaker by turning on the breaker, and then add the devices 1 at a time. If the light or device becomes operable, then a voltage tester is not needed.


Use a voltage tester to see if power is going out through the wire attached to the breaker.


Turn off the branch breaker boxes, followed by the main power.This should be the large flip switch located above or below all the other smaller ones. It should also be labeled "main" or...

Electrical problems can be among the most mysterious and frustrating that pool owners experience. They are also dangerous to the untrained DIYer so great caution – or a licensed electrician – is required when attempting to diagnose. Here are the most common reasons we see when it comes to pool pumps tripping.


GFCIs are quite sensitive to moisture so if your breaker trips after a storm, you might just need to let the sun do its thing for a day or two. If it’s not summer, you can probably just leave the pump off for a day and try again once everything has had a chance to dry. In summertime, you can still get by with your pump not running for one or two days but it will require some extra chlorine (shock) and manual circulation with a pole or paddle a couple times per day.

Keep in mind that rain isn’t the only possible source of water. A misdirected sprinkler, spray from power washing, even high humidity can affect a GFCI.

Bad or Wrong...

The breaker blows either because the load on it is too great (this is what iot is designed to do, protect the electrical wiring and pump motor from an overload condition), or because the breaker has become defective.

There is a good chance the pump needs maintenance -- it may be experiencing more friction as part wear out or deposits build up, causing it to consume more power. Lower than normal water levels can aggravate this. This in turn makes the electric motor work harder, pulling more current, and eventually tripping the breaker. Higher than normal demand (constant running to feed the shower for example) can also make this problem occur more frequently.

The other thing to consider is that breakers can go bad in a manner causing them to trip at lower currents than they are rated for. If you know how, you can probably isolate power from reaching the pump breaker and replace the breaker first, which will doubtless be a lot easier than pulling the pump up out of the well...

Our well pump motor was recently changed (it was making a huge racket, burning up switches one after the other etc. The bearings were going out). Smooth sound, no more burnt switches, water pressure is fine (the switch is a 40/60).

Before that, there were no problem with it tripping a breaker, it was in a bad shape, but it worked (even if, as previously mentioned, it was burning through switches.)

Now, we noticed it tripping a breaker in the evening only (so far), sometimes multiple times in a row, sometimes not. We live in an old house, but have a brand new breaker box. The pump supplies this house and a small trailer where a couple of tenants live.

As far as electrical circuit configuration goes, we do not know whether or not the pump lives on its own breaker (a 20A single pole as far as I can tell) or shares it with something else. So far it doesn't seem like there is anything else on that breaker.

I'm thinking of sanding the hot wires going to the...

Well, it sounds like you've eliminated one of the least likely sources of the problem: the circuit breaker. (The great majority of the time a breaker trips, it is simply doing the job it's intended to do.)

An obvious follow-up question: In putting in the new septic system, was any digging done close to the wire run? And even if the digging itself wasn't close to the wire, was there heavy equipment on or around the run?

Since the breaker stopped tripping when you switched the pressure valve from auto to off, you might want to start there.

Does the switch have three positions (on, start and auto) or only two? If it has a "start" or "on" position, will the pump run and deliver water with the switch set to on? Or does the breaker trip when the pump starts or tries to start?

(Note that you should be careful not to run the pump too long with the system closed while the pressure switch is "bypassed" since it's possible to build up too much pressure. Watch the...

Possible Cause

Corrective Actions To Check/Try

Pump won’t start or run

Voltage being fed to the pump does not match its rated voltage

Confirm that the voltage you have connected to the motor is what the motor is rated for.

Fuse or circuit breaker in your fuse/circuit breaker box has tripped or blown

Inspect wiring, pressure switch, etc. for a problem that caused fuse/breaker to blow and repair as needed. After that is fixed, reset breaker or replace fuse.

Voltage at pump motor is too low

Measure voltage at motor when it is trying to run. Compare to base voltage that is being fed to it. If running voltage is 5% or more below the base voltage check wiring for poor connections or wiring that is too light in gauge for the pump’s horsepower and wire length.

Power wires are loose / disconnected

Answer for USA, Canada and countries using similar 60Hz mains suppliesAnswer

Any socket outlets or wiring to pumps, etc must be protected by a GFCI, not only by the main circuit breaker on the house AC power supply panel.

Sounds like there is water somewhere in the circuit and that is causing the GFCI to keep tripping every time you press the RESET button. The GFCI is doing its job to protect you and your family from electrocution.

Turn off all power at the main panel and then check all wiring, junction boxes, outlets, etc. in the circuit for water. Every part of the circuit must be allowed to dry thoroughly before the GFCI will allow you to reset it. Then be sure to protect any connections in the circuit from getting any water spray or splashes in future.

Really this work should be done by a licensed electrician who will know exactly where to check and what to do to make your electric pool pump - and any socket outlets in the same circuit - safe to use in...

1) Not likely the timer is problem, unless there was fire or overheating in timer box. Use nose and eyes to inspect for signs of high heat.

2) Eliminate timer as suspect:
Move wires on timer to test if timer relays have gone bad.
Move terminal 4 to terminal 3
Move terminal 2 to terminal 1

3) Check watt rating of Hayward pump, and voltage.
1Hp motor at 240Volt draws 8 amp, and can draw 6 to 8 times that amount when starting. Up to 100 feet, should be at least 12 gauge wire and double-pole 20 amp breaker. Over 100 feet, 10 gauge wire and 30 amp double-pole breaker is best.

4) Intermatic T104 240V timer is rated 40 amps
Can safely handle 1 Hp motor without nearing heat-rating capacity of timer

5) Make sure the motor is wired correctly for 240Volts.
If motor is wired for 120, and 240 is...

Breakers are a safety device. It is designed to protect not only the equipment but the wiring and the house as well. So when it trips, there is a reason and it should be taken seriously.

One very common cause for breakers to trip are loose electrical connections and can easily be corrected by tightening them. Try one time to reset it by turning it to the “off” position and then back to the “on” position. Do not just keep resetting it and try to ignore the situation. It is trying to tell you something.

And while it may be just a weak breaker or the result of a thunderstorm, always remember that you are dealing with high voltage, high amperage and possibly high temperatures which can cause serious damage to life and property. Note that breakers should not feel hot to the touch. If it is hot, it indicates a problem and not to be ignored.

For example, if when you reset it, it immediately trips, that is usually indicative of a direct short. Do not even try to...

There are several different ways to do this, but one of the simplest is just to plug anything at all which communicates with smartthings into that outlet and then use the community – created "simple device viewer" Smart app to notify you when that particular device is no longer responding.

I believe @a4refillpad uses that smartapp for this purpose, and might be able to say more.

And here's the thread for the smart app if you decide you want to use it.

There are some Beeper alarm devices which are not networked, but you might be able to pick up their alarm with a Leeo acoustic sensor and then have the Leeo notify SmartThings through IFTTT. Quite a few people are doing that for existing smoke alarms or water leak alarms. The problem is the Leeo itself requires mains power so it would have to be plugged in on a different circuit than the one that keeps going out. So that may not be practical for your particular use case.

People used to do this with the...

Troubleshooting Well Problems

No water? Low water pressure?

There are several issues that can cause a loss of water in your home. Below is a list of concerns to look for before you call a professional.


Are you experiencing a complete power outage Check circuit breaker for power (turn breaker off and on to reset – sometimes doesn’t show completely tripped) Check for buzzing or chattering from control box relay or capacitor Check pressure gauge (clock like dial at your pressure tank(what number does it read Turn on faucet to check gauge for proper functioning (needle indicator should go lower) Is pump starting up and immediately kick off Is the pump going on-off, on-off Is there clicking or chattering at pressure switch(3”x4” grey box at pressure tank usually says “square D” on it) Is pump coming up to pressure, shutting off and immediately loosing pressure with no water usage (watch pressure gauge dial)

OK, so the circuit breaker tripped. You go to the basement and locate the electrical panel, reset the circuit breaker and "pop", it trips again,

or it trips again when you go back upstairs and turn back on what you were using when it tripped in the first place. At this point you need to

stop and identify the root cause of the problem making the circuit breaker trip. Circuit breakers are designed to trip

(fuses in your fuse box are designed to blow) and turn off power when any of the following dangerous situations occur:

An overloaded circuit is the primary reason for a breaker tripping and occurs when a circuit is has more connected electrical

load than it is supposed to have. When more current runs through the circuit than the circuit was intended to take, the circuit

breaker is designed to, well,"break the circuit."Circuit breakers come in different ratings that determine how much current they

will allow to flow through the...

We carry the other brands, but Hayward pumps and filters have always been our flagship line.

Reliable & durable, Hayward pumps will still likely need some type of troubleshooting at some point during your relationship.

Often what appears to be a pool pump problem is actually a filter problem or a valve problem, so the first step is to rule out any mis-aligned valves or obstructions in the filter or pipes.

Barring problems with other pool equipment, a pool pump problem will either be an electrical issue or a plumbing issue. On the electrical side, problems can occur with the electric motor, timeclock, breaker or wires. On the plumbing side, you can have problems with air leaks, water leaks or just getting the water to flow properly.

Electrical circuit breaker keep tripping. A few of my circuit breakers are turning off daily. I have to constantly flip them back to ON. What would cause this? I just moved into an older house and the breakers are old. The breakers in the electrical breaker box are NOT labelled. I am thinking there is a problem with my homes electrical wiring system. I am worried something will overheat and may cause a fire. I have been unplugging things and using less electricity to try and be safe. Is there something that I should test, check, or troubleshoot? How do I isolate which appliance or wiring issue is causing my electrical problem?

What is a circuit breaker?

A circuit breaker is a safety mechanism that cuts off electricity – or "trips" – when an electrical circuit has overloaded. It serves the same function as a fuse box.

Some student rooms have their own circuit breakers (sometimes located in the closet) that students can control. In other cases, there is a centralized circuit breaker for multiple rooms, which students cannot access.

Has my circuit breaker tripped?

If electronic devices at a particular power outlet or multiple power outlets suddenly turn off or do not receive any power, then your circuit breaker has probably tripped.

How do I reset my circuit breaker?

First check to make sure your room has a circuit breaker (it may be in your closet).
Next, turn off your light switches and unplug all devices from the affected power outlet(s). Open your circuit breaker box, and find switches that are in the middle position between "on" and "off." Move...

Let us guess.

You noticed your heat pump isn't warming your home. So you decided to check the circuit breaker and saw that the heat pump's breaker is tripped. You flipped it back on and everything was good for awhile.

But then the breaker tripped again.

What’s going on?

First, turn off the heat pump immediately and call a heating repair professional to find the problem.

The circuit breaker is doing its job by tripping and cutting the power before something worse (like an electrical fire) happens. There’s a problem that’s causing your heat pump to pull more power than it should.

Let’s look at some of the most common problems that can cause your heat pump to trip the breaker.

Dirty air filter
A dirty air filter restricts airflow in your air duct system, forcing the heat pump’s blower to work long and harder to circulate air around your home. Working this way causes the blower to trip the breaker.

Check the air filter at...

Check for discolored water or smells. A well that has rust, brown or black elements in the water requires a treatment system to correct the problem. Residential wells, depending on their location and geographical region, can be drilled into areas that contain iron, sulfur, calcium, magnesium and other naturally occurring minerals. Iron, for instance, leaves rust stains or can grow iron bacteria inside your toilet tanks, creating a soft red-brown fur. Manganese leaves black stains on clothes and forms a coating inside refrigerator water lines. Contact a water treatment specialist in your area to fix this problem. Under-counter or faucet filters are not sufficient to correct the...

It is common for a circuit to cover parts of two rooms. That way, each room has two or more breakers so any one breaker tripping doesn't leave a room powerless. This does make finding the source of breaker trips harder since you have to find all of the outlets on a circuit. It is also common for non-code modifications to be made after construction.

Depending on your video card, it is possible you added 110 watts or more of additional load to that circuit. If you were close before but under the total breaker load, the additional load might have you almost maxing out the breaker. I am not a breaker expert but I think there are two trip modes in a standard(non GFI or newer) breaker. One is a immediate trip for a hard short. A second is thermal based based on steady current draw. A 20A breaker will allow a short term over draw to allow motors and other gizmos with a high start up current to start. If you run close to the limit, it is possible a 20A might trip at 18A steady draw if the...

All HVAC problems seem to be connective. If we have air flow problem, it will affect the refrigerate cycle and Ac components.

For example, homeowners will call us and said he needs an Ac Freon. We will always ask him basic question, like. Did you change the filter? Usually, it’s not the Freon, it’s the ac filters. He doesn’t know that air flow will affect the refrigerant.
