KDTE104ESS104 Kitchenaid dishwasher not cleaning

Recommended Posts

jkmhb

As title says.

What I've observed:

- Dishwasher fills and drains OK.

- Dishes don't clean, soap does not dissolve.

- Most of the time sprayer does not spray. It does spray once in a while, more often on Proscrub setting, almost never on Normal setting.

- The filter is clean.

- No error codes on normal service. I have not yet run diagnostic.

- Run time seems very long. Even though it does not clean dishes.

- I'm almost certain it is not ever heating the water.

I suspect the turbidity sensor. Am I on the right track?

Thanks!

Do you hear water being circulated during wash cycle?

If water is being circulated I would disassemble and clean spray arms and sump area.

Spray arms are clear.

Most of the time water does not circulate, but some times it does. It more often circulates when on Proscrub. Almost never circulates when on normal.

If motor is getting power, most likely there are food particles stuck in the screen down in the sump. This will diminish the "cleaning power" of your dishwasher.

Pop off the cover with a star bit and remove gray cover, clean the screen wicked well. Have seen problems where it affects the pump, easy to pop in a new sump on this model.

Thanks to all for your help. Last night I went through diagnostics and then I was going to do the voltage test.

During diagnostics, it gave a 5-1 error (door error, because I don't think I closed the door quickly enough after I started the test).

Then when it was done I ran a test cycle.

Then I ran some dished through.

Darn thing is working OK now. How is this even possible?

If it fails again I will do more testing.

I have the circulate pumps be flakey and not work intermittently. If it is running then run it till it stops again then do voltage test.
