Questions & Answers

For Whirlpool Dishwasher Rinse Aid Dispenser Wax Motor (Part Number: OEM18040821)

1 Answer

Hello David! Is the machine draining properly? Check the drain hose for a clog or a kink. If it is not, you may need an impeller kit 12001489. Is the machine draining and then filling overnight? If so, you will need to replace the inlet valve WP99001359. With water being in the tub and the unit adding more water to it when filling this will cause too much water within the dishwasher and cause it to leak even with new gaskets. Hope this helps!
