While some dishwasher repairs are best left to the pros, some are easy even for people with zero appliance repair experience. Here's list of some common dishwasher problems with easy DIY repairs that take less than 30 minutes to complete, with links to step-by-step instructions.

If your dishwasher is flashing an error code, you can find out what it means on our dishwasher error code page.

You can find links to all our dishwasher repair help on our DIY dishwasher repair page.

Water sprays wildly or not at all

The dishwasher lower spray arm directs water onto the dishes. The spray arm can crack along its seam, spraying water all over the tub and even through the door. Or sometimes gunk can clog the spray arm, keeping water from passing through.

Replace the spray arm with the directions in our DIY repair guide How to replace a dishwasher lower spray wash arm.

Water leaks through the door

The door seal, also called a gasket, forms a watertight barrier between the dishwasher tub and door. A worn, torn or cracked seal can let water leak through the door.

It's easy to replace the seal, and we have the instructions in our DIY repair guide How to replace a dishwasher door seal.

The door won't lock

If the dishwasher won't start, the problem could be a failed component in the door latch assembly; the dishwasher runs only if a switch in the door latch assembly senses that the dishwasher door is latched.

See our DIY repair guide How to replace a door latch assembly if you need to replace the door latch.

Cycles don't progress

The timer moves the dishwasher through the wash, drain and dry cycles. If the timer stops working, the cycles won't progress like they should.

Replacing the timer is a simple repair with the instructions in our DIY repair guide How to replace a dishwasher timer.

The door panel is dented

Dings and dents on the dishwasher's outer door panel won't affect how the dishwasher works, but they can be unsightly.

Replacing the outer door panel is an easy job. Find the instructions in our DIY repair guide How to replace a dishwasher outer door panel.
