I seem to have a complex issue. I read through a bunch of threads here and cant seem to get everything working properly.
I have the WDT720PADM2 Whirlpool dishwasher. I got it in 2016.
I replaced the circulation pump about a year ago, and since then my dishes have not been drying. I replaced the heat element, but it turns out the old one was fine. I read here (today), that I should have run a diagnostic cycle to reset everything. After doing this, the heat element turns on and gets hot but the dishes do not dry. I checked all of my resistances and everything is fine.
I get error codes F7E1, F3E3, and FE.

Please let me know what else I can try...

Ok, I'm posting what it says for F3E3 below. Make sure the drain hose has a high loop in it, because you had to probably remove it when you replaced the circulation pump last year. Also it says to remove the OWI sensor and clean the lens on it.

Here's the OWI sensor for your model:

Hi Jake - I have this same model with error code F7E1 error code. I saw on an older thread where (I think) you gave some guidance with this code but a different model.

Symptoms: dishwasher doesn’t seem to be cleaning dishes well, sometimes dishes seem to have not gotten water on them at all and other times they are soaking wet. I believe the first step is to test the continuity of the heating element and perhaps also the water inlet valve. I can borrow a multimeter from my neighbor, but what setting should it be set to, where exactly do I put the probes, and what measurement should I see?

Thank you I’m advance!

Hi,

Lets first run the SERVICE DIAGNOSTICS CYCLE, and let it run all the way through to reset it back to default.

Entry sequence: Press any 3 keys in the sequence 1-2-3, 1-2-3, 1-2-3 with no more than 1 second between key presses. NOTE: Some models have replaced the “Clean” LED with “Completed.”
The Service Diagnostics Cycle will start when the door is closed.

--->Invoking Service Diagnostics clears all status and last run information from memory and restores defaults. It also forces the next cycle to be a sensor calibration cycle.

LET IT RUN ALL THE WAY THROUGH: Service diagnostic cycle will take about 23 minutes.

Do that now, and report back.:)

If that doesn't fix it READ BELOW:

sometimes dishes seem to have not gotten water on them at all
It's usually the wash motor, this has become a common problem as of late, many members here have reported the same. In fact I had 2 in Sept. 2018 in Parker, Arizona that did the exact same thing, and the new wash motor fixed them both.:)

That will also cause the error code 7-1.

Look at post #7 here:

I'd first check to see if your getting 120 volts to the wash motor when it should be in the wash cycle. His Kenmore 665 is made by Whirlpool, and uses the exact same wash motor yours does.

Take the wire connector off the wash motor and use your multimeter to see if yours is getting 120 volts when it should be washing, if so and it's not running order the wash motor below.

Here is the wash motor assembly you can order:
W11032770 Motor-Pump


Here's the video to replace it:

Its actually less expensive to get the complete sump/wash motor assembly, and the diverter comes with it too:
