Thanks again for the help [USER=”4209″]electrofix[/USER]

I managed to get it into Diagnostic Mode by some combination of turning the dial and holding Start/Pause and the button above it. It showed an error code E57, which as you very correctly suggested is a motor fault. I ran through some of the Diagnostic checks and as I’d tentatively concluded from trying to run the normal wash-cycles, it would appear to fill and drain with no issues but anything to do with the motor is a total no-go, so all makes sense.

A quick Google suggests that the E57 fault is down to high current on the Inverter PCB and could be down to the motor or the inverter board itself. I’ll whip them both out this evening to have a proper inspection and to take note of the exact model numbers etc, I was just wondering if you had any tips for helping to diagnose which one might be at fault?

Some Googling suggests measuring the resistance of the various pins on the motor (connecting to the motor windings?) and values should be between 3-6 Ohms, does this sound at all sensible?!

Many thanks again for all of your help, Adam

Many thanks for the quick reply… I did manage to remove and inspect the inverter board as you suggested… quite recognisable by the huge 400V capacitors! There wasn’t anything obviously amiss with this, although didn’t want to test with a multimeter after your warning.

If this isn’t the issue, would the next step to be to drop the motor out and see what’s going on there?

Also, are you aware of how you might put this particular model into diagnostic mode to see if I can retrieve an error code? I’ve tried all the recommended methods of holding Start/Pause + other buttons whilst turning the dial to the first position, but no luck. Just wondering if there’s a different method for these newer models. It has a fascia as per the one in the video linked below (not my video but same model!) and I’ve included the part numbers of the electrical boards below

That’s great, thanks for the reply. I pulled the PCB this evening to take a look for blown capacitors etc and couldn’t see anything untoward… looked a lot simpler than previous appliances I’d pulled apart actually.

How would I go about diagnosing if it is indeed the motor?

​​Many thanks, Adam
