How to Deal with Common Automatic Dishwasher Problems

The advent of the automatic dishwasher did away with the family dilemma of who was going to wash and who was going to dry. Not only does this appliance make family life easier, but also when things go wrong, most are easy to repair. Here are some fairly common problems:

Nothing happens – Is there electrical power to the unit? Also, there is a switch in the dishwasher door. If this is not engaged, the unit will not start. The timer may also be suspect. Try this: turn the timer dial just a hair, and if nothing happens, the timer is the problem; or just find out more from Pittsburgh Appliance Repair about dishwashers and their common problems. You could even call them for help if you are unable to make sense of whatever is happening.

Doesn’t fill – There are two controls for water. The first is a float switch that rises up as water comes in and, when it rises to the proper water level, it shuts off. It is inside the dishwasher, and most resemble a plastic cup turned upside down. Lift up on the cup and you should hear a click, which usually means the switch is OK.

The other is a solenoid valve that is in the water supply line. It is easy to spot because it has a pair of wires running to it. Shut off the hot water under the sink. Place a shallow pan under the switch, disconnect the wires, and remove the switch. Test it for continuity. There is often a screen that should catch mineral deposits. If clogged, soak it in vinegar and poke out the debris with a needle, you should also check this Helpful Tips to Avoid Clogged Drains in the future.

Over fills – The float valve isn’t working. Test your washers for continuity and look for any obstruction.

Dishes don’t get clean-The most common cause is water that is not hot enough. See if the water heater setting is too low. Often the distance between the water heater and the dishwasher is far enough that you don’t get hot water until the dishwasher is well into the wash cycle. Before starting the dishwasher, run water at the sink until hot. The heating element may not be doing its thing. Check it for continuity and replace it if faulty. Another possible cause is that the spray arm(s) are clogged. A pipe cleaner will take care of that. You can also contact a professional to check it for you (visit website for more details).

Won’t drain – A clogged drain is one of the most common issues you’ll encounter when using a dishwasher. Check the drain hose to see if it has become kinked. Lift up the screen in the bottom of the unit under the bottom spray arm. There may be food scraps or broken glass. If you’re really adventurous, remove the top of the pump and take the impellers out to look for clogs or broken fins. As soon as you find out what’s causing the problem, search “Appliance Repair Near Me” to get it repaired ASAP.

Only partially drains and has food particles in remaining water-Drain hose going into disposer has low spot and when the pump stops, gravity lets water drain back into dishwasher. Loop hose up so it’s higher than the inlet to the disposer. If need be, use a cup-hook and twist-tie to hold it in place.

Leaks around door-The door latch may be bent. Or, the door gasket may need to be replaced. Check this website for gaskets online

Leaks underneath – You’ll have to look underneath to see whether there is a hose leak or a loose connection that needs tightening.

Detergent dispenser doesn’t dispense-Often the use of detergent powder will end up caking and prevent the detergent dispenser from working. With the door open, flood the dispenser with vinegar. If the dispenser needs to be replaced, the door liner must be removed.
