Motto trips breaker - Hayward Pool & Spa

get in an electrician to check the equipment and the circuits

Does the circuit breaker trip before squeezing the switch? Check the power cord - there's a short

Does the chain move freely before squeezing the switch? If not, and the circuit breaker trips while squeezing the switch, your chain is too tight.

Bottom line - tell us when the breaker trips and what you were doing when it tripped.

Yes they get weak over time.
The main will trip when it senses heat.
Use hand to feel if main breaker is getting hot.

A tripping circuit breaker is an indication of an overload. You say there is no load on the breaker - how are you making this determination? Are you using an amprobe or some other meter?

A circuit breaker with NO load shouldn't ever trip. Likewise a circuit breaker carrying up to 80% of of the current it is rated for shouldn't trip either. Circuit breakers that carry more than 80% of their load will trip - if the load remains connected long enough. This is called "duty factor" or "service factor" The greater the load is in excess of 80%, the less time that the breaker will carry it before tripping.

An example of a 100 amp breaker with different loads on it (this 100 amp value was chosen for ease of doing the math):

80 amps - never trips
85 amps - trips after 48 hours
90 amps - trips after 16 hours
95 amps - trips after 8 hours
100 amps - trips after 4 hours
105 amps - trips after a few minutes
120 amps - trips after a few seconds
150 amps - trips instantly

This is only an example to show how a certain circuit breaker might trip under a load less than the rating stamped on the body or handle.

A circuit breaker that trips with no load or a load equal to or less than 80% of its rating is most likely defective. You need an amprobe or ammeter for amp readings. If the load is found to be 80% or less, there may be an issue of harmonics that is causing the tripping. You'll need to have special equipment and qualified persons to check harmonic problems. Most harmonic problems occur when the loads are not linear device (transformers). Examples of non-linear devices are "switching" (or solid state) power supplies like those in computers.

I hope this helps and good luck. Please rate my reply. Thank you.

A shunt trip breaker operation.

It works just like a normal circuit breaker with one additional function. A shunt-trip breaker also has a built-in magnetic coil that can be energized externally to trip the breaker.

So what is wired to the shunt that is not letting the breaker reset?

leave off the oven and a/c breakers and plug dryer and reset the breaker. if not tripping occurs then one at a time trip back the oven first. if no trip then trip off again and trip the a/c. if no trip then trip the oven back. if trip you may have a wire problem. if dryer trip any way then possibly you have a short in dryer. check the heating element wires,power cord at the dryer side(terminal block).

The circuit breaker may be tripping because of a fault with the dryer or it may be a fault with the circuit breaker being weak.

From the description you give the circuit breakers trip frequently.

I'd suggest you first try selecting the no heat air fluff cycle and run it to see if the breaker trips. If the circuit breaker doesn't trip in air fluff then there is likely a short in the heating element.

With a clamp-on amp meter you can read the amp draw of the dryer when it is heating. With the motor and element both working you would see approximately 25-26 amperes being drawn. The breaker is rated at 30 amps. If the breaker trips and only 26 amps are being drawn then the breaker is the problem.

Try the air fluff cycle first and see if the breaker will trip. Then with additional details I may be able to help you further.

My motto with all electrical systems is: If all else fails reboot. Find the breaker that controls the dishwasher and switch it off for a couple of minutes. this will clear out the electronic buffer. and reset the systems. make sure that the door is not closed, reset the breaker and try to restart your dishwasher.

It's possible that the first breaker that you said does not trip - it could be that breaker is failing to trip on a bad circuit. That is, it could be you have a bad circuit but that first breaker is not detecting it and pretends everything is OK. If your new breaker trips on the first breaker's circuit, the curcuit it probably bad and the breaker in not working properly. The most common problem for failed circuits is a stray ground wire in a box somewhere in the curcuit resting against a hot or neutral wire. You'll have to take apart every connection on that curcuit to find it. Not fun.

When this breaker tripped, it did not go fully to off. Push the breaker all the way off and then all the way to on. It should be fine. If not manually push it to full off once again and then back on. If both attempts fail the breaker will have to be replaced. good luck.
