Four months ago the dishwasher was not heating the water properly... ultimately replacing the heating element did the trick. The dishwasher ran great without issue for four months and now, the past few days the dishwasher has been showing similar issues with not heating the water properly.

I would not think the element would go out so quick following replacement...weirder things can happen I guess. Dishwasher goes through complete cycle without stopping/issues/errors however the dishwasher is not warming up like it should to more thoroughly clean dished and dry them.

Hi,

Here's your service manual: https://drive.google.com/file/d/15CmFe-hcufL5XUJPsqlEN3AzwDZ6z0M-/view?usp=sharing

Page 73 starts the section on the heating element, then on page 74 do the flow chart steps to determine the cause of your heating element problem. You will need a multimeter to do that flowchart with.

Let us know what you find.

--->The TCO is located on the right side of the tub, approximately 16 inches from the front of the tub. On your model its underneath the pump, so you will likely need to pull the dishwasher out to get access to it. Make sure you disconnect power to your dishwasher FIRST!

The TCO is in a series circuit with the heating element, if that TCO is bad(open) it will never heat.

TCO=Thermal Cut Off

Here's the TCO for your model:

Its the SILVER METAL part integrated into that wire harness. See the black button on the back of it? That's the RESET BUTTON, PRESS IT and see if that solves the NO HEAT problem.

Here's the photo of it:
