I have a Whirlpool ADG 957 (service number 854295715410)

Customer Question

I have a Whirlpool ADG 957 (service number 854295715410) which is beeping and the start light flashing.

When I run the test cycle it stops with the 1st and 2nd lights alternating flashing, and the 3rd light on (not flashing).

Anyone know what this test result means?

If you have lights 1 and 2 flashing then this is a filling issue F7 error code. It picks up water is entering but not full enough or fast enough.

This is can be down to a blocked pressure sensor or the flow meter on the side of the dishwasher.

Remove the bottom basket and the filters and then look inside the sump and on the right hand side you will see a black round grid. Pore boiling water into the sump and with an old tooth brush give the grid a scrub. As this can block up so as the water fills it doesnt activate the pressure sensor and then the control board error codes out and it stops.

Once the grid is cleaned set it going on a hot wash and see how it goes from there.

But if its still the same then remove the left hand side panel and there you will see the plastic filling tank.
In there you will see the flow meter. It will have a small wiring block going to it. Remove this and refit it a few times as this can clean the contacts up and make a better connection. So then retry it and see how it goes.

But if again its still not right then remove the outer door panel and access the wiring harness in the door and open the plastic cover and give each wire a tug and see if theres a broken wire there.

If all thats fine then its either a faulty flow meter or pressure sensor. We used to replace both parts for this fault if this was the case and that cured the fault.

But try the above first and see what you find. But the error code you have is F7 which is a filling issue.

If you need anymore info just get back to me.
