Dishwasher Heating Element Won’t Turn Off (Fixed!)

Dishwasher Heating Element Won't Turn Off

Basically, your dishwasher heating element won’t turn off due to a vast number of reasons.

…On a normal basis, it is expected that the heating element of your dishwasher gets turned off immediately after a cycle is completed.

There was a time when I finished running a cycle on my dishwasher and suddenly the heating element failed to shut off at the right time when it’s supposed to.

Sometimes, the dishwasher might have completed a wash cycle, but in return the heating element stays on whenever the door is closed. 

Prior to this experience, I would be highlighting a step-by-step guide focused on the reasons why this might be happening and the ways to fix this issue.

Why Your Dishwasher Heating Element Won’t Turn Off?

Realistically, there are a few causes or reasons why your heating element always turns on or fails to shut off after a cycle.

This exact problem is typically a general phenomenon which usually occurs to most dishwasher users. 

This happens when the heating element is completely damaged, if the timer is blocked or a faulty control board.

Below are the reasons why the heating element of the dishwasher isn’t working as expected.

  1. The control panel is faulty.
  2. The heating element is damaged.
  3. The thermostat isn’t working perfectly.
  4. The dishwasher spray arm is obstructed or blocked.
  5. The dishwasher timer is faulty.

The Control Panel Is Faulty Or Damaged

You need to realize that the control board or panel is practically responsible for shutting the heating element on or off amidst other actions.

If a slight error or damage occurs to this component, it might be unable to pass instructions to the heating element. 

Therefore, leading to the inability of the dishwasher heating element to shut off after work.

You need to pay more attention to the control panel, it just might be a possible cause of the issue with your appliance.

The Heating Element Is Damaged

It is safe to deduce that problems with the heating element are directly related to not being able to shut off at a particular point.

When the heating element is damaged, the temperature required to warm water up to a particular degree won’t increase or get dishes sanitized.

A faulty heating element is also another reason why the heating element is not heating sufficiently or failing to turn off.

The Thermostat Is Faculty Or Not Working Perfectly 

A thermostat is another vital component of a dishwasher which is also involved in the adequate functioning of the heating element.

The thermostat is responsible for regulating the water temperature and enables the dishwasher to heat up to a certain temperature level.

However, a defective thermostat won’t be able to reach this specific temperature as it also won’t have access to turn the heating element on and off.

The Dishwasher Spray Arm Is Obstructed Or Blocked

If there is an object obstructing the rotation of the spray arm, it might indirectly be keeping the heating element switched on. 

This is another reasonable cause of the problem which most dishwasher users don’t pay much attention to.

Appliances are made to be smart and be able to detect unusual situations in its surroundings.

Therefore, the dishwasher might assume that a wash cycle is currently ongoing if the spray arm is blocked or not able to spin properly.

Definitely another reason why the heating element might be triggered by the dishwasher to stay on…

The Dishwasher Timer Is Faulty

When you are not told to do something, you definitely won’t follow any instructions whatsoever.

Situations like this are similar to how a dishwasher timer works. If the timer is damaged or probably worn out, it won’t be able to control the timing of the heating element.

This could result in continuous or indefinite indication of the heating element as it fails to shut off after a wash cycle.

To check for any blockages, start by detaching the bottom of the rack for inspection. 

If you find any blockages, ensure that you get it removed in no time. These are some of the easiest fixes you can try.
