How do I replace an Upper Rack Height Adjuster in a Dishwasher?

During the drying cycle, the vent opening at the bottom of the dishwasher door allows the fan to get hot, moist air out of the dishwasher. If the vent doesn't open or the fan doesn't run, the dishes won't dry. The dishwasher stops in the middle of the cycle if the fan fails and the control panel goes blank. If the fan or vent fails, replace it with a new one.

If the detergent dispensers are cracked or leaking, replace them. If the detergent dispensers don't open properly during the dishwasher cycle, you may need a replacement. The entire dispenser assembly should be replaced if the latch is broken.

The dishwasher door hinges are attached to the spring. The door can be opened and closed in a controlled manner with the pivot on a pin. The door won't open and close properly if the door hinge is damaged. The door hinge should be replaced in that situation.

The dishwasher drain pump should be replaced if it's cracked or damaged. Make sure the drain path is not blocked before you replace it. The drain pump will fail if the drain path is clear. If the drain pump won't run, it's time to replace it.
