We have already had the problem of the plastic bits flying off and ending up in the motor housing, but we checked again and this is not the same problem. We took apart the base of the washer and cleaned and examined all the pump parts, but can't see any reason for the noise (except the black gasket which appears to have been all stretched out and loose). It's especially bad right after starting- before filling starts. But is noisy during later stages as well. Now what? Thanks so much for your help!

HI, Most likely a defective pump.
The function of the pump is to pressurize the spray arms and to drain the water.
The pump typically consists of two separate compartments one for wash and the other for draining.
The wash part of the pump consists of the wash impeller and the filter components.
The drain portion consists of a drain impeller and a chopper blade.
The impellers are driven by an electric motor that is attached to the bottom or side of the pump.
