Question: Hi, my two-year old Whirlpool Gold Dishwasher, Model Number GU2451XTSB1, works but only intermittently. The light always light up and sometimes it starts and sometimes it doesn’t. Is there a series of tests to perform in order to figure out what parts to replace?
If you remove the plate at the bottom of the dishwasher (kickplate). You should be able to find a tech sheet on the other side that will tell you how to test things.
The door latch switch is a safety switch that prevents the dishwasher fromworking if it is defective. When working properly, the switch doesn’t allow power through it when the plunger is out, and it allows power when the plunger is in. If the plunger is broken or if the internal parts are not working properly, power is stopped at the switch and it needs to be replaced.
The timer and the selector switch are other possibilities. If one of these is defective, your dishwasher won’t operate normally, and the part will need to be replaced.
Running the dishwasher regularly may help prevent any seals from drying out and sticking. This includes the motor seals.
Visually inspect the wiring to see if any looks disconnected or burned. Repair or replace as necessary.
