To repair a Whirlpool dishwasher, first identify the actual problem. Common problems with Whirlpool dishwashers include power supply problems, faulty water inlet valves, clogged wash arm assemblies and malfunctioning drain pumps.
If a Whirlpool dishwasher does not run, first confirm that the appliance is switched on and that power cord is plugged into a functioning electrical outlet. Reset tripped circuit breakers, and replace blown fuses. If the problem persists, examine the door switch and latch assembly. Replace a defective door switch or a broken door latch. If this does not fix the problem, replace the timer and touch pad if defective.
If the dishwasher is leaking, begin by checking the water inlet valve, wash arm assemblies or door seal. A defective water inlet valve allows water to fill the dishwasher continuously. Replace the water inlet valve if it cannot be fixed. However, if the water pressure is low, replacing the valve may not solve the issue. Check whether any part of the wash arm assembly has cracked, and replace it if necessary.
If the dishwasher is making noise, start by examining the drain pump and pump impeller. Clean out a dirty drain pump and impeller, or replace it if it is faulty. If the problem continues, check whether the motor bearings are worn out, and replace them accordingly.
