Dishwasher Repair: How to Diagnose and Fix It



Doing the dishes isn’t exactly America’s favorite pastime, but a hard-working dishwasher makes the task much more tolerable—and quicker—so we can get back to things we actually enjoy (like anything but the dishes).

One of the most common problems is that your dishwasher won’t turn on. When that happens, here’s what you need to do.

Step 1: First, make sure that you haven’t accidentally locked the control panel. Some machines have a “lock” button that prevents the machine from starting and it can get pressed by mistake.
Step 2: Check the door latch to see if it is allowing the door to close properly. Most dishwashers will not start until they are fully closed, and if the latch is defective it could prevent the machine from starting.
Step 3: Check the door switch to make sure it’s working properly. Use a multimeter to test the switch for continuity. If it has no continuity, you’ll need to replace it.
Step 4: Check the thermal fuse to see if it’s burned out. Use a multimeter to test the fuse for continuity. If it has no continuity, you’ll need to replace it.
