How it works

When the door closes it presses against the gasket, which flexes and seals the gap. The gasket is usually pressed into a channel or held by clips.

Signs it is failing

A tired gasket can trip leak or base-pan codes once enough water gets under the machine. Check it whenever you see water at the front.

Can you replace it yourself?

Wipe the gasket clean and look for cracks, flat spots or gaps at the corners. Most gaskets pull out of their channel and the new one presses in by hand. Use the wrong detergent or too much of it and suds can push past even a good gasket.

Always unplug the dishwasher or switch off its breaker before opening any panel, and turn off water or gas where relevant.

Buying the right part

Buy the gasket for your exact model; length and profile vary between models, and some machines also use separate corner baffles at the bottom of the door.
