I have a GE Profile Performance Dishwasher.
The drain loop goes up to the outlet by the sink faucet and then
connects to the disposal, which I think is proper.
The water fill cycle starts, then a few seconds later, it starts
draining. If I watch under the dishwasher, I can see a spring loaded
plastic piece move when the pumping starts and then return to its
starting position after the water is pumped out.
The spray cycle then starts, but of course there is very little water
left in the tub to be sprayed.
If I add a half bucket of water into the tub and start it up again,
the water is again pumped out of the tub.
I have tried cleaning out the drain line at the sink. I have also
removed the two covers inside the dishwasher, 1) a long one at the
back and 2) an oval one on the right middle part of the dishwasher.
These areas were primarily clean, but I removed any residue that was
in there and replaced the covers.
I have also removed the cover from the flood switch in the front left
of the machine and cleaned all of the residue out of it. If I push on
the switch I can hear it click.
Any ideas as to what I can try next???
