Self Help

Dishwashers may occasionally exhibit problems that are unrelated to a malfunction of the dishwasher itself. The following information may help you with a dishwasher problem without your having to call a repair person.

Dishes do not dry

The rinse agent dispenser may be empty. Check the rinse agent dispenser and refill it if necessary. Dishware drying can be accelerated and enhanced by opening the dishwasher door slightly and propping it open with the top rack.

Indicator light(s) do not come on

Check the fuse or circuit breaker at your fuse box/breaker box and replace the fuse or reset the breaker if necessary.

Dishwasher does not start

Make certain the dishwasher door is shut and latched.

Suds in dishwasher

You may have used the wrong type of dishwasher detergent. Use only automatic dishwasher detergents.

White spots or streaks left on dishes and glassware

Go to the Rinse Agent Adjustment section of this manual for instructions on increasing the amount of rinse agent.

Water not pumped from dishwasher

Make certain the drain hose isn’t kinked, clogged, or improperly installed. Make certain a portion of the drain hose is at least 20 inches above the dishwasher’s enclosure floor (see the Installation Manual). Filters may be clogged. Make certain the filter system isn’t clogged (see the Care and Maintenance section of this manual). The kitchen sink drain may be clogged; you may need a plumber rather than a serviceman for the dishwasher. If an air gap is installed at sink, it may be clogged.

Dishwasher runs a long time

May be due to cold incoming water. Before starting the dishwasher, open the hot water faucet at the sink nearest the dishwasher. Run the water until it runs hot, then turn off the water and start the dishwasher.

Rattling noises

Utensils may not be properly arranged.

Machine cycle does not advance to rinse NOTE: The Installation instructions that came with your dishwasher will help you with the following instructions.

The water supply line may be shut off. Check the water supply valve and open it if it’s shut.

Detergent dispenser cover will not shut

You may not be correctly shutting the detergent dispenser cover, or a cycle was not finished and should be canceled. Go to the Adding Detergent and Rinse Agent section of this manual for instructions on shutting the detergent dispenser cover. Go to the Operating the Dishwasher section of this manual for instructions on canceling a cycle.
