What is the purpose of the check valve WD1X5488? Does it affect the cleaning process? Thank you
Answer Hello Brian. The check valve is used to prevent water from flowing back into a location where is should be drained from. If it is bad, it can allow dirty water into the machine.
Does the check valve assembly include the rubber check washer, which is the part that I need? Thanks for your help.
Answer Hello Henry! No, a washer does not come included with the check valve part number WD1X5488. This is the dishwasher check valve flap used on the lower spray arm support. Thanks!
