Whirlpool ADP4501 Cant get a diagnostics

[garryhucker]

Hi everyone, new here and looking for some advice on this problem I have with this dishwasher.
I’ll note a few things first.
1. The machine “Pulses” everytime I run a cycle, wether it finishes a cycle or not.
2. No errors codes show on any cycle.

OK so, I goto start the machine, select the cycle and the drain pump starts pulsating, everyone 1 or 2 seconds, in sequence with the start light lighting up with every pulse, however it does eventually drain after about 5-10 mins, then the fill process begins, again its pulses while filling in sequence with the start light lighting up.

Now, once its filled it will start the next cycle, wash, rinse whatever, however sometimes it will continue to fill and eventually overfill and flood the kitchen, or sometimes it will work as normal and finish its full cycle. GREAT
But, sometimes when it does finish the cycle there is a lot of water left at the bottom (level above the filters).

I not sure wether the issues are related, several parts have been replaced, the Drain pump, and Inlet valve are two of them, and ive also removed the water indicator (the black grid) and cleaned out and tested its continuity when the button is pressed and depressed, the numbers on the multimeter change so Im guessing that’s fine (or can they still be faulty even when testing seems ok?)

I think it has something to do the the pulsing (only on drain and fill does it do this)

Sometime its will do a full cycle as normal (no leaks and all water drained at the end) but these cycles take twice as long as they should.

Im starting to think its the PCB module

Any advice is greatly appreciated as im at my whits end, and these so called appliance technitions on just answer just want your money for mis diagnosing you which happened to me twice when I changed the drain pump and inlet valve.
