If the latch assembly on the dishwasher door isn’t working, the door won’t latch and the dishwasher won’t run. The problem could be the latch itself, or it could be the microswitch that tells the electronic control board if the latch is closed. Fortunately, the latch assembly includes both components, so you just have to replace the latch assembly with the right dishwasher replacement part. This repair guide offers detailed instructions for accessing and replacing the door latch assembly in a dishwasher.
This repair procedure works for some Kenmore, Whirlpool, KitchenAid, Maytag, JennAir and Amana dishwashers. You also can use the same basic process to replace the door latch assembly on GE, Frigidaire, Electrolux, Samsung and LG dishwashers.
