Why haven’t my dishes dried when the dishwasher finishes?
If you have issues with your dishes being wet when at the completion of the dry cycle, look to see if the rinse aid dispenser needs to be filled, also check to see if the dishes are loaded properly, and make sure a bigger item isn’t blocking smaller items.
Did you use the right amount of detergent? Too much or too little detergent can have a negative affect on how well dishes dry. Make sure you have selected the heated drying option? A rinse aid can help your dishes to dry better too. Check to see if the rinse aid dispenser is empty?
The next couple of things to check are the filters, drying fan, drain valve, heating element, and the thermostat. Every now and then a clogged filter will stop all the water from being able to leave the dishwasher. Clean or replace clogged filters. A broken drain valve that leaves too much water in the cabinet can be the problem. Is there a lot standing water left in the unit after the dry cycle finishes? Search for blockages at this valve.
Some dishwashers have a fan that moves around the cabinet air to assist in drying the dishes. If the fan is not working right, you may need to replace it. On the floor of the dishwasher is a heating element that heats the air in the dishwasher. The increased temp. increases the evaporation process and decreases the drying time. Take a look at the element and look for any broken or burned areas on it, and if it’s burned out it will need to be replaced.
There is also a thermostat that determines the water temp. and drying temperature. If the thermostat is broken, the cycles may not finish right. If it’s broken, you need to replace it. You may want to take out the dishes in the bottom rack initially so that any water left pooled on dishes in the top rack won’t fall onto the bottom rack’s dishes.
