THE DISHWASHER ONLY DRAINS SOMETIMES.NO CLOGS ,IMPELLER SPINS FREELY,DO YOU THINK THE DRAIN PUMP WORKS INTERMITTINGLY OR SHOULD I BE LOOKING MAYBE ELECTRICAL. I DONT WANT TO START BUYING PARTS I DONT NEED.MACHINE IS 7 YRS OLD.
ANSWER Chuck, you're on the right track. It is more likely to have an intermittent or failed drain pump WD26X10039 than a defective control board WD21X10241 or wiring at this stage. You do want to make sure the filter screens and sump chamber are clear of any sediment, chemical build up or debris. You also may want to disconnect the drain hose from the plumbing, and drain the dishwasher into a bucket, a few times, this would clear any debris from the drain hose.
