Anyway, the DW fills up partially then stops. The float barely gets wet and the DW does not stop filling because the float switch is activated. Then it sits for a few minutes and then drains. Then it fills up again partially and stops and that’s it. No wash, no nothing. I haven’t actually waited to see if it would drain again after about 3 hours at the end of the cycle.

The DW seems to cycle through. The Inlet is clean and relay is good. The Float moves freely and the switch is also good. The drain cycle works fine, but I couldn’t get the proper reading on the solenoid for the drain pump (but I think it’s fine since I can just force it to drain). I tried metering the wash motor and I was getting 1250 ohms at first which is no good, but then there was a spot where I got 15 ohms twice but it was really hard to get that reading… so I have no idea if the motor is good or not. And I tricked the door latch and same issue.

From what I have read in one of the posts, it is likely the Wash pump that needs replacing, but the partial filling of the tub is suspicious.

Any help would be great,

Thank you in advance for your time

Hi!

I am reaching out for some guidance on my Whirlpool dishwasher, model WDT750SAHV, which has been showing some inconsistent behavior lately. I have observed a few issues and conducted some preliminary diagnostics:

• Initially, I noticed that the detergent tablets were not dissolving completely, and there was some residual moisture inside. Currently, only the 1hr wash cycle seems to function properly.
• With standard programs (e.g., Normal), I hear the drain engage, water enter, and then a long period of silence. It seems like the dishwasher thinks it's washing because I eventually hear the soap dispenser open. However, there are extended periods of silence, intermittent sounds of water, and at the end, some dishes are still slightly wet.
• I managed to run the diagnostic mode, which returned error 4-3. While I couldn't find the tech sheet for my specific model, a similar model's tech sheet (WDT790SAYM) suggests this might indicate an issue with the wash motor (not running). This is puzzling because the 1hr wash program appears to operate normally.
• During diagnostics, I hear a sound that seems to indicate the motor is trying to start but might be obstructed.
• I have cleaned the turbidity sensor, filters, and checked for any obstructions.
• The heating element seems to function as it gets very hot during drying (sometimes).
• I plan to repair it myself and have considered ordering the "Pump and Motor Assembly W11087376" but the part is quite expensive, and I want to exhaust all other possibilities first.
• There was an incident of water leaking from the door during a cycle, which I promptly stopped. I'm concerned about whether this could have affected the electrical components, although issues with the dishwasher existed before this incident.

Given these observations, I would greatly appreciate any advice or suggestions on further troubleshooting steps before proceeding with purchasing new parts. Could there be an underlying issue I might be overlooking?

Thank you for your time and assistance!
