Turned off main circuit breaker for maintenance for issue not related to pool and failed to turn off pool pump. After the restoring power the pump stopped working. I tried to turn on the intermatic timer manually, but nothing happens. Could it be the timer,motor,capacitor...? Need help troubleshooting.

if your hot tub is tripping the breaker, it could be due to a worn out ground fault circuit interrupter (GFCI) breaker, which is responsible for preventing electrical surges. You can try flipping the breaker to see if it trips again. If it does, then you may need to replace the breaker.

Another possible cause of the problem could be loose electrical connections in your hot tub . This can lead to power fluctuations that cause your hot tub circuit breaker to trip. Professional electricians can inspect your hot tub and tighten any connections that are loose, which should fix the circuit breaker problem.

If your spa is not receiving power, you should check your home's circuit breaker to ensure that it's not tripped . Reset the circuit breaker if it's tripped to restore power to the spa. If the circuit breaker keeps tripping, it may be an indication of an electrical problem, and you should call a professional electrician to diagnose and fix the issue

i am going to assume its a VS pump. turn off the main breaker for 5 minutes to allow the system to reset. turn off the breaker to pump as well. after reset period, turn on main breaker first then the pump breaker.

Get a new electrician! The pool pump should be on its own isolated circuit, usually on no larger than a 30 amp GFCI protected breaker. You said it was replaced but he only treated the symptom, not the cause. This one will take on site troubleshooting to find out why your whole house is affected.

If the device that tripped is a ground fault circuit interupter (GFCI) breaker or receptacle then it is likely caused by 5mA or more of leakage current to ground within the motor. If what tripped is a circuit breaker then there are likely shorted turns within the motor. Usually either of this issues requires a new motor.

If you are not wanting to turn wrenches yourselfthen my best suggestion is to bring it to Leslies Pool Supplies and they oftencan put it right for the price of the parts while you watch (they might not have some parts in stock).

I hope this helps.

I would try a different breaker.

That circuit breaker is letting you know that you've got a problem in the electrical wiring.... What's next is to turn the power off to BOTH legs of the breaker.
Begin by physically inspecting all the connections in the timer box, and at the breaker and all the way to the pump motor. Make sure all connections are dry, and there's no water in any of the conduits...this will cause a short circuit and trip the breaker. If there's any bare power leg wires touching a grounding point , this can cause the breaker to trip. Lastly check the motor on the pump; on the motor end, there should be a cap you can remove and use a crescent wrench to make sure the motor shaft is moving freely. It could be jammed with debris....this happens around my pool often because I'm surrounded by trees with needles. If the motor cannot turn freely, this will cause the breaker to blow... I'm pretty sure that your timer isn't the issue... Please let me know what you find out.

turn all breaker off that are related to the pool equipment even the one at the main panel. if not check for power 220 v at the timer if power check the wires if not power the breaker may need to be replace

Something doesn't sound right here. You indicate 2 200Amp breakers. With a single service entering the house, this is not possible. The "sub-panel" to the pool house is more likely a 100Amp setup, yes? If not, you have a bad setup and it should be corrected. I would suspect that you are attempting to pull too much current to the pool and that is what is tripping the breaker. Also, these breakers should not be run over about 80% of their capacity for the long haul. If they are, they tend to age and get either real sensitive causing tripping when it shouldn't or you can run 500Amps through it and it won't trip.

My suggestion is to revisit the setup. If the pool house is fed from the main panel, make sure that the breaker for it is not 200Amp. Second, try disabling the pool house breaker to see if that is the source of the problem and look more closely there.

Keep us posted.
