Fill the rinse aid dispenser so it is full if your dishes are not drying properly. Add more rinse aid if your dishes have white spots, or take some away if you are left with streaks.
Replace a fuse or reset the circuit breaker if the indicator lights on the dishwasher do not work.
Turn on the hot water faucet that is nearest the dishwasher and let the water run until it is hot if your dishwasher completes a cycle but takes an extra long time to do it. Your water supply may not be hot enough.
Switch to an automatic dish-washing detergent if you have suds inside the dishwasher when a cycle finishes.
Ensure that the dishwasher door is closed and latched properly if the dishwasher won't start.
