Check that you supply hot water to the whirlpool dishwasher not drying dishes. Compared to the cold water, the hot water evaporates quickly. The Whirlpool dishwasher needs hot water to dry the dishes.
Coldwater does not evaporate quickly. Hot water evaporates quickly. Whirlpool dishwasher washes dishes using hot water.
The minimum temperature of water supplied to your dishwasher should be 120 ℉.
Reasons For Whirlpool Dishwasher Not Drying Dishes
Is your whirlpool gold series dishwasher not drying dishes even after receiving hot water? A part malfunction can account for a whirlpool dishwasher not drying dishes.
You need professional repair in case of a part malfunction. The following parts ensure that your whirlpool dishwasher keeps the dishes dry:
- Vent Fan
- Heating Element
If any of the above parts malfunctions, then your whirlpool dishwasher will not work properly. You should look for the following:
- Broken vent
- Failed vent fan
- Defective heating element
Steam accumulates in a whirlpool dishwasher due to a broken vent. It is the job of a vent in a whirlpool dishwasher to let the steam escape.
In some cases, the vent in the whirlpool dishwasher does not open properly. As a result, steamy air accumulates in your whirlpool dishwasher.
You need to replace the broken vent in your whirlpool dishwasher.
Failed Vent Fan
Some dishwashers use a vent fan. A vent fan blows steamy air out of the dishwasher. A vent fan may stop working properly.
You should check whether the blades of the vent fan are moving freely or not. Vent fan blades spin due to their motor. If the motor of the vent fan malfunctions, then the vent fan blades may stop moving.
As a result, steamy air accumulates in your whirlpool dishwasher vent. Dishes remain wet due to the failed vent fan.
To drive the steamy air out of your whirlpool dishwasher vent, you must replace the failed vent fan.
Defective Heating Element
Some whirlpool dishwashers contain a heating element. The purpose of a heating element is to drive hot air into the dishwasher after every washing cycle.
Dishes remain wet due to the malfunctioning heating element. You should check through multimeter testing whether the heating element is showing continuity or not.
You must replace the malfunctioning heating element.
How To Diagnose A Faulty Heating Element?
Please follow the following steps:
- Disconnect the power to your dishwasher.
- Disconnect the drain plug.
- Disconnect the water hose pipe.
- Disassemble the dishwater.
- Check all the wires connected to the heating element.
- Check all the components connected to the heating element.
- Remove the heating element.
- Check the heating element with a multimeter.
Defective Heating Element Assembly
A malfunctioning heating element assembly can leave the dishes wet at the end of the drying cycle. You should check the heating element assembly through multimeter testing for continuity.
If your heating element assembly has no continuity, you must replace it.
High Limit Thermostat
The high limit thermostat controls the voltage passed to the heating element during the wash cycle. A malfunctioning high-limit thermostat can stop the voltage of the heating element.
As a result, the high limit thermostat shuts down the heating element at the wrong moment. It is unlikely that your high limit thermostat can malfunction.
Check all the other parts before you try to replace the high limit thermostat.
A thermostat keeps in check the internal temperature of your whirlpool dishwasher. Like a high-limit thermostat, a thermostat controls the voltage flown to the heating element.
A malfunctioning thermostat can shut down the heating element at any moment. A thermostat cannot malfunction easily.
You should check all the other components before deciding to replace the thermostat.
The heating element has a circuit known as the heating element circuit. The control board controls the flow of electricity to this heating element circuit.
A malfunctioning control board can render several components useless. As the control board shuts down the flow of electricity to a component, the component will not work.
A malfunctioning control board can render the heating element useless.
A good diagnosis is critical at this stage because a good diagnosis can save you a lot of money, time, and effort.
Many technicians misdiagnose that the control board is defective without checking other parts properly.
Ensure that you have checked other parts properly before concluding that your control board is defective.
Like the control board, most of the technicians misdiagnose the control module. The control module controls the flow of electricity to the heating element.
A malfunctioning control module can shut down the heating element at any moment. A heating element can become useless due to a malfunctioning control module.
Control modules rarely malfunction. Before concluding that your dishwasher has a defective control module, you should check all the other components.
Main Control Board
The main control board is the master of your machine. It controls the flow of electricity to all the other components of your machine.
A malfunctioning main control board can turn off any critical component and turn on the other vital components at the wrong time.
A malfunctioning main control board can shut down the heating element. Your whirlpool dishwasher cannot dry dishes properly without a well-functioning heating element.
Companies maintain strict quality control for the main control board. The main control boards do not malfunction easily.
Technicians can easily misdiagnose that the main control board is defective. It is essential that you check all the other components before deciding that your main control board is defective.
The timer affects the flow of electricity to the heating element circuit. A malfunctioning timer can shut down the heating element circuit.
Your whirlpool dishwasher will not be able to dry the dishes without a functioning heating element circuit.
A novice technician can easily misdiagnose the timer in your whirlpool dishwasher.
Ensure that you have checked all the other parts before deciding that you have a defective timer in your whirlpool dishwasher.
You must replace the defective timer.
Dishes Not Loaded Properly
Your whirlpool dishwasher may not dry dishes due to overloading or improper loading of dishes. Overloading the whirlpool dishwasher stops the flow of hot air.
A rack-by-rack loading technique dries dishes faster.
Unloading In The Wrong Order
It would be best if you always unloaded the bottom rack first. If you are unloading the top rack first, then there are fair chances that the trapped water in the top rack will make dishes in the bottom rack wet.
Drying Plastic Items
Plastic items do not hold heat. Whirlpool dishwashers cannot dry plastic items.
Heated Dry Not Selected
Select the heated dry function before you start the washing cycle. This makes the heating element ready to be used for the drying stage at the end of the wash cycle.
New Whirlpool Dishwasher Not Drying Dishes
It is unlikely that your new whirlpool dishwasher is not drying dishes due to a part malfunction. Companies conduct quality control tests to ensure that new whirlpool dishwashers wash and dry dishes properly.
It is improbable that the following parts will malfunction in your new whirlpool dishwasher:
- High limit thermostat
- Control board
- Control module
- Main control board
You should check the following:
- Check that your whirlpool gold series dishwasher not drying dishes is labeled as “Quality Control (QC) Passed.”
- Check if you are supplying hot water to your new whirlpool dishwasher.
- Check that the minimum temperature of hot water supplied to your dishwasher is 120 ℉.
- Check whether your new whirlpool dishwasher works with a vent, a vent fan, or a heating element to dry the dishes.
- Make sure that your new whirlpool dishwasher is installed correctly.
- Check if the hot water is leaking and not being supplied to the new whirlpool dishwasher.
- Make sure that you are properly loading dishes into your new whirlpool dishwasher.
- Make sure that you are unloading the dishes correctly in your new whirlpool dishwasher.
