Hayward EcoStar VSP continually tripping circuit breaker

I have a Hayward EcoStar variable speed pump, model SP3400VSP, it is 5 years old, continually shutting off, usually tripping the circuit breaker, but not always. After resetting the circuit breakers, it will restart, but the time before shutting off again has gotten shorter and shorter, 3 day, 2 days, 1 day, and now it's almost immediate. Sometimes the screen on the pump's user interface says, "Drive Error! Power Interrupted", which the manual says "the line power supply was disconnected and reconnected too quickly and that the input current limiter is resetting itself". Several other error codes with "Drive Error" (not displaying) indicate "the drive may need to be replaced", but that's not what this one says so I hesitate to have it replaced (as 1 repair person has recommended) if it's some other electrical problem, especially since the motor drive is $1,100.00 plus installation. I have read several comments about this same problem that said it's the circuit breaker that needs to be replaced and more than one person even recommending Siemens circuit breakers to not have this problem with this pump, (but it's worked for years with the breaker I have now). What direction do you think I should go?

Winston,

I agree with Dave.. but faced with the choice of a new drive or a new circuit breaker, the breaker wins every time... Even if I thought it was the drive, I would try a new breaker first.

I assume that the pump's breaker is a GFCI breaker... As a test (only) you could install a cheap standard 20 amp breaker and run it for a few days and see if it trips, or if the pump shuts off. If so, you will know for a fact the pump is faulty..

Thanks,

Jim R.

I would swap the breaker as advised above and see if it holds. Before I spent 1100 on a drive I would order a tristar vsp for less than that and swap it yourself the plumbing lines right up and they have simple pump unions very easy to screw off. I have an ecostar too its 2 years old and I had a tripped breaker 2 weeks ago for no reason. When mine goes I will ne swapping the whole pump even though the drive costs me about 500ish. I have the newer style ecostar that supposedly has its issues fixed but not holding my breath. It is a great pump tho and I really like it overall

Yes, it just seems to make sense. I'm going to try a new circuit breaker first. If I didn't, I would always be wondering if it would have fixed the problem.

Thank you. I'm going to try replacing the circuit breaker first. If that doesn't fix the problem, I probably will replace the entire pump.
