Tips for maintaining your appliances

Dishwashers

A dishwasher has many parts that can become blocked, jammed or clogged.

Very hot water -- 140°F to 160°F -- is basic to good service from a dishwasher.


Some dishwashers are equipped with an air gap to prevent waste water from backing up into the washer. Because it collects bits of waste, the air gap must be cleaned regularly (remove the cap and cover and use a wire).


A dishwasher without an air gap has a high loop in the drain hose. Make sure that it's not kinked, and clear any obstructions from it with a length of wire when necessary.

Safety Tip:   Before making repairs, pull the plug from the receptacle. Turn off the hot water valve under the sink before working on the water inlet valve or disconnecting the hot water hose.

You can't get the dishwasher to run.
