I fitted a new pump yesterday. Two wash cycles and one dry then completed without issues.
I noticed the new pump felt a bit stiffer when rotating the rotor. Hopefully that will be it fixed.

Thanks for all the responses/comments received.

[ploane]

Thanks both for additional replies.

All points noted with thanks.
It is looking more like the pcb than the pump, as the wash cycle pump out completes without issues. The pump out after rinsing is failing. Once manually pumped, the cycle completes. Bit annoying as the machine is otherwise in good condition. Have the electronics improved over time or would a different brand be advisable?.

Thanks again, “flick round in quarter turns” would describe what I have observed I think. Will recheck. There is no lateral movement of the end of the impeller. By manually draining when it “froze” I was able to get the number 5 wash cycle to complete to the end. This following a first cycle which completed without any issues.
Is an intermittent pump failure more likely than a control board failure given the symptoms reported in your experience?

Thanks. Regards

Your earlier question “Does it have the pump filter on the front, either way does the pump impeller feel a bit loose with side to side movement?”
When you asked if the impeller felt loose side to side, did you mean in a circular motion?

I can turn the impeller with my fingers, but it is not a smooth turn, there is a point in the turn where there is a bit of resistence, which feels “rubbery” rather than hard or grating (if that makes any sense)

Thanks.
Machine has just stopped for third time at the same stage described in previous posts .
I manually drained it a little, as I still have outlet hose into sink, and the cycle has continued on.

Would this suggest an intermittent pump failure? And how would I confirm.

[ploane]

Behavior of previous post repeated. Restarted again by turning On/Off.
Additional water being added at each restart.

A second wash cycle started ok, then quickly seemed to freeze at start of cycle (Vertical LEDs 1 (bottom) and 6 (top) illuminated)

Pressing Start/Pause button did not achieve anything
Pressed On/Off and cycle resumed and is progressing as expected.

Any suggestions appreciated.

Wash cycle completed no issues. Started a second one, with outlet pipe into sink.
The only difference I can determine with regard to outlet pipe is that when run into sink it is higher relative to machine than when run into standpipe.
Having said that, machine has been working run into standpipe for 8-10 years

Where is the worm pump you mentioned?

Running a cycle now with pipe over sink
Checked the standpipe is clear, by running a hosepipe to it, no sign of blockage
Pump filter at front, pump impeller does not feel loose, no side to side movement at all
Pump emptying smoothly into sink

Waste pipe goes into a standpipe, not connected to under sink plumbing
I will see if I can run reach it to side of sink and run a cycle and see what happens

You suspect a blockage then ?
How might a blockage explain water accumulating in the drum while drying?

Thanks again.

Hi
I have checked the pump, outlet hose, and ECO ball fitting and found no blockage
I removed and cleaned each to confirm and found only very limited sludge in the pipes.

I took a look at the circuit board and could see some light black dusting on some components
All capacitors looked fine (no blackening or bulging)
Black dusting observed on yellow components (?) and white box components (relays?) on the board
Board itself had no signs of damage

Any comments appreciated as to what if anything this might suggest

Regards

Peter

Thanks for replies iadom and electrofix

[ploane]

Hi Dave
Thanks for the response.
I will take a another look at the drain hose, and pump.

What is the purpose of the plastic ball you mention ?
How would I determine it is causing a problem ?

As you indicate blockage as the problem are there any other locations to investigate ?

Thanks. Appreciated

Re: Whirlpool ADG 7440 continuous warning light flash rinse

Thanks for the reply
I actually did not change the water indicator, as the problem disappeared after letting the machine sit unused for about 3 months.

I spoke to a local Whirlpool repair guy who suggested it may have gotten stuck mid cyle and leaving it sit let it “relax” out. Sounded a bit off but machine did start working fine again for about a month. Now I have this new problem…

Should I now change both ?
Am slow to work on it as it is built in tight into kitchen unit.
