I have a 11 year old Fisher and Paykel DD603 dishwasher. The other day I looked in the drawer and it had a few inches of water in it. I assumed it was not draining. Cleaned the filter, the drawer basin, and snaked the drain hose. I ran a an empty load and it worked and drained as it should. A few hours later I looked and the drawer had a few inches of water in it again. From that I am assuming that it is draining fine but is filling from the water supply line. Is there an intake valve that is malfunctioning allowing supply water to enter the basin? Any ideas of what to look for and replace? Thanks...
