I have a Whirlpool QuietPartner II Imperial Series Model DUL200PKB1 that will not drain.
Inside the dishwasher I took the bottom apart and cleaned everything, sucking out the drain as well.
I also removed the hose from the disposal and sucked that out as well with a wet/dry vac to ensure there were no blockages.
After reinstalling everything, the dishwasher would still not drain. I then hit the Cancel/Drain button and it drained!
After that I ran a rinse only cycle and it drained completely. I ran the Normal wash again and it did not drain. I ran the heavy wash cycle and it drained as well...
Why would the normal cycle not drain but all others do?
Thanks for your time and help.
Model Number: DUL200PKB1
