Make sure that the soap dispenser on your Maytag dishwasher is clean and dry before you add any powdered detergent. If you pour dry soap into a wet or greasy dispenser, the soap can become wet and clump together. This will prevent it from being rinsed out of the dispenser during the wash cycle. You can thwart this by wiping the soap dispenser clean with a damp cloth after each use and then drying it with a soft, clean cloth.
Only use automatic dishwasher detergent in your Maytag dishwasher to avoid undissolved soap or over sudsing. While the type of detergent you use is important, the age of it is also a factor. Stale or old dishwasher detergent might not dissolve properly, according to the Maytag company. You should store detergent in a cool, dry place and keep the container closed when you are not using it. This will keep the detergent fresh and help eliminate soap clumps in the dispenser.
When you fill the dishwasher, make sure that none of the dishes block the soap dispenser. These dispensers usually have a door that will open during the wash cycle to release the soap and clean your dishes. If a plate, cookie sheet or a pan presses against this door, it will not open and the soap will remain in the dispenser.
The hot water entering your dishwasher must be at least 120 F to dissolve the soap and remove all of the food from your dishes. You can test the temperature of the incoming water at your kitchen sink. Fill a glass with hot water from your tap and test it with a thermometer. This temperature is the same as the water entering your dishwasher. If the temperature is too cool, adjust it at your hot water heater.
