if your Whirlpool Dishwasher is Not Heating Water. 

so don’t worry this is a common issue with Whirlpool Dishwasher. 

in this guide, we explain 7 common reasons for this problem with unique solutions. so let’s start now.

Whirlpool Dishwasher Not Heating Water

1. Thermostat Issue

Cause

The thermostat controls the water temperature in your Whirlpool dishwasher. If it’s faulty, it may not signal the heating element to heat the water. 

This issue could occur due to a malfunctioning thermostat or a loose wiring connection.

Solution

To fix this, the thermostat should be checked for continuity with a multimeter. If the thermostat doesn’t have continuity at any cycle, it should be replaced. 

Please ensure this diagnostic and repair process is handled by a certified professional to avoid any electrical hazards or further damage to the appliance.

2. Problem With Heating Element

Cause

The primary cause of the dishwasher not heating water could be a faulty heating element. 

If the heating element is not working properly, it prevents the appliance from reaching the necessary temperature to effectively clean your dishes. 

This can lead to unwashed or poorly cleaned dishes even after a complete wash cycle.

Solution

To resolve this issue, the heating element should be checked for any signs of damage or wear and tear. If the element is indeed faulty, it will need to be replaced. 

It’s advisable to get a professional technician to handle this task, as it requires handling electrical components which, if improperly managed, could risk personal safety or further damage to the dishwasher.

3. Electrical Issues

Cause

The cause of your Whirlpool dishwasher not heating water could be an electrical issue. The heating element requires an adequate power supply to heat up. 

If the wiring or connections to the heating element are damaged or loose, the dishwasher may not receive the power it needs to heat water.

Solution

The solution involves inspecting the wires and connections to the heating element. Unplug your dishwasher and remove the bottom panel to gain access. 

If you see any damage or loose connections, they will need to be repaired or replaced. 

It’s recommended to hire a professional technician for this process to ensure safety and proper handling.

4. Broken High Limit Thermostat

Cause

The high-limit thermostat is a safety mechanism that keeps the dishwasher from overheating. 

If your Whirlpool dishwasher is not heating water, it’s possible that the high limit thermostat is faulty or broken. 

This failure could be a result of normal wear and tear or a malfunctioning control system.

Solution

The defective high-limit thermostat must be replaced to resolve this issue. 

To replace the thermostat, disconnect the dishwasher from the power source and remove the inner door panel to access the component. 

Once the faulty part is removed, install the new high-limit thermostat and reassemble the dishwasher. Always ensure to procure a high-quality replacement part from a reliable source.

5. Malfunctioning Control Board

Cause

When your Whirlpool dishwasher is not heating water, a common cause might be a malfunctioning control board. 

This integral component regulates the heating element, ensuring that the water temperature remains optimal during the wash cycle. 

A glitch in the control board can disrupt this function, leading to the dishwasher operating with cold water.

Solution

The primary solution for a faulty control board entails professional repair or replacement. 

Although it’s advisable to seek assistance from a certified technician to prevent further damage, some homeowners with technical skills might manage to replace the control board by following the manufacturer’s instructions.

Always remember to disconnect the dishwasher from the power source before attempting any repairs.

6. Blocked Water Inlet Valve

Cause

The Blocked Water Inlet Valve is a common issue that may cause the dishwasher not to heat water. 

This concerns the valve that allows water to enter your dishwasher. 

If it’s partially blocked, it may restrict the flow of water, preventing the dishwasher from filling and heating to the desired levels.

Solution

To fix the Blocked Water Inlet Valve, one must first ensure the water supply to the dishwasher is turned off. 

Then, locate the water inlet valve (usually found behind the lower kickplate panel in either the right or left corner). 

It’s paramount to clean or replace the valve if blocked or faulty. Remember, it’s always wise to call in a professional if you’re uncomfortable performing these actions yourself.

Conclusion

To sum up, the issue of your Whirlpool dishwasher not heating water can be attributed to several factors. 

The most common culprits are a faulty heating element, a malfunctioning thermostat, or a defective high limit thermostat. 

It’s crucial to diagnose each part for any signs of failure to ensure your appliance operates optimally. 

However, dealing with electrical parts can be risky, and it’s always recommended to consult with a professional technician when in doubt. 

Remember, a well-functioning dishwasher not only ensures clean and sanitary dishes but also contributes to the overall efficiency and convenience of your kitchen.
