How to replace a dishwasher diverter motor

How to replace a dishwasher diverter motor

This DIY repair guide gives step-by-step instructions for replacing the dishwasher diverter motor. The diverter motor moves the diverter disc into position so the disc can direct water through the upper spray arms. If the diverter motor fails, the dishwasher stops and signals an error code. Replace the diverter motor with a manufacturer-approvedreplacement part if the error code indicates that the diverter motor failed. To prevent damage to a newly installed dishwasher diverter motor, also replace the grommet seal (part WPW10195677) if water leaks through the seal. The grommet seal is the gasket around the diverter motor shaft where it meets the bottom of the sump. A leak can damage the diverter motor, as well as counters and flooring near the dishwasher. This procedure is for Kenmore, Whirlpool, KitchenAid, Amana, JennAir and Maytag dishwashers.
