I have a inground pool and pentair 2HP pump. It was running fine for 5 hours and stopped working on it's on. I am switching the power on but there is no response. Is it a pump problem or some electricity issues. Thanks in advance for your help. Take care, Monika

Thank you for posting your question here on Fixya.com.

It does not hum or buzz or anything? If not I'd start with looking for a tripped circuit breaker. If there is nothing tripped then the motor has either tripped is thermal overload and it needed to cool off or it is dead and needs to be repaired or replaced. If it is the overload it will start working again within an hour, maybe two. That is a sign of an internal problem that needs to be corrected soon or the motor will fail permanently.

If the breaker tripped it too is a sign there is a more severe problem that needs to be addressed before the motor fails beyond repair.
