Dishwasher Versus Generator

We've found that our dishwasher is apparently incompatible with the sine wave of the Onan generator causing the dishwasher to continuously click when the generator runs and won't turn off. The dishwasher is fine on shore power. Onan blames the dishwasher and FisherPaykel blames the generator. We'd never use the dishwasher if we were where we'd need to run the generator anyway so we're just adding a switch to toggle the power to the dishwasher when the generator is running. I just wondered if others have run into this and what their solution was.

Can you just turn the dishwasher's breaker off at your converter?

I could, but I wonder if turning the breaker off and on with some frequency might cause it to fail earlier. And because the breakers are near the floor I'd have to get down on hands and knees to get to it. I don't do hands and knees well any more.

Thanks,

Breakers can be switched on and off many times without failing. Do what works best for you and don't worry about shortening the life of the breaker. Besides, they are cheap and easy to replace.

Of course, a switch is a more convenient solution.

Thanks, I'll keep that in mind. I did get the switch installed and I'm pretty happy to be able to turn it on and off without getting on the floor.

I think I would be checking the neutral and ground from the generator to the transfer switching, also check the grounding and neutral from the dishwasher to the power distribution panel.

The service dealer checked it all out and determined it to be a problem with the sine wave coming off the generator which Onan and FischerPaykel seem to acknowledge but offer no solution as they blame each other for the incompatibility.

Thanks,

The only surge protector used when the service dealer diagnosed it was the included SurgeGuard 41260 transfer switch/surge protector.
