Hi folks
Went to this yesterday – This is a compact m/c with an EWM1000 module and configuration – fault is tempremental and gets to a state of not starting.
Tested on spin – stated up ok – canceled off prog
Tested on rinse – stated up ok – canceled off prog
Tested on wash – wouldnt start
Retest on spin – wouldnt start
Hear click and door interlock disengages and door can be opened. m/c still wont start or door lock up.Tried to access diagnostics – wont let me access
End of prog light flashes 11 times – nothing else
Cant make head or tail of Distripart manual to what 11 flashes mean apart from its the first part of the falut code and that it might mean “B”
Customer states on the rare occassions they can get it working it will complete program and continue to do so unless they move program dial to through Zero to another program program.
Questions – to me this looks like a module fault but could be a prosible door interlock braking down. But if it was the door interlock i was under the impression that you should still be able to access diagnostics? And on the rare occasions it works and complets the program wouldn’t it have broken down then?
This m/c is on a barge and a load of units have to be dismantled to access properly, even the door interlock! (why do customers never give thought to m/c access these days? :rolls: ) but before I order a non returnable module just wondered if there were any more thoughts out there – especially the 11 flashes
If it was ther door interlock wouldnt it be 4 flashes (door not closed indication).
Any comments/ suggestions appreciated – Thanks
Mick
Re: Zanussi ZWC1300W – module or door interlock?
Most likely fault from what you describe & taking into consideration the location is a power supply problem. These are very sensitive to voltage or frequency fluctuations.
Re: Zanussi ZWC1300W – module or door interlock?
Thanks for the reply Seamy
Wonder if you could just explain this a bit further for me – because what I think you are saying is a low voltage could be the cause. This might be possible because chatting to cust there are 2 power supplies – one land line and the other direct from the boat.
But i think this is happening on either but will just conferm with cust.
Thanks

Been back intouch with cust – uses on mains voltage but he is going to check the voltage and get back to me
Thanks

This sounds like a neutral problem that I had with a Zanussi model recently… Have you done a resistance test on the supply wires to the module?

Thanks for reply Allsorts
No diddn’t do a resistance test on wires – looks like it might be 20min job to dismantle units and get m/c out :rolls: so must admit i didnt want to do that only to do repair.
Can you explain further what the problem was – presuming you are saying there was an earth fault on the neutral – caused by what? – and why would it start to work and then stop ?
Thanks
Mick

So the ‘Start/Pause’ LED is not flashing at all then?

One of the wires (Neutral) had a break (intermitant connection) inside the insulation…
We only found the problem by doing a resistance check on the wires leading to the PCBGeorge
Re: Zanussi ZWC1300W – module or door interlock?
Thanks for the replies folks.
Sounds a posibility then Allsorts – thanks – but wouldnt it loose the supply to the lights but there again if there was a small voltage getting across it might be enough to light them?
It is only the end of prog light that is flashing Martin – But I cant get it to go into a diagnostic mode to get the other to flash – This is the one that flashes at the customer when there is a fault and the first digit of the fault code – you have to get into diagnositic to bring up the second digit dont you? – I’m not even sure it means anything – I’m just putting it on the post incase it does. It says something in the diagnostics about 11 flashes means “B” (i think – not sure) but without the other digit I cant make head nor tail 😕
Have told the customer I need better access to the m/c to diagnose further and are waiting for them to get back to me atm. (Built in under the corner of two work units and the door only opens about 60deg to get washing in – have to crouch down under work surface to access controls :rolls: )
Thanks

Out of interest Mick,
Did you resolve this problem or not?
Cheers

Hi Poppins
No never solved problem – customer went and bought new m/c :(.

Hi Mick,
Oh that’s annoying and bad luck for you! It would have been nice to have got to the bottom of it. Thanks for the update anyway. I was curious as I have had a similar thing happen to me in that the Zanussi machine was giving strange symptoms which pointed to either the motor or the PCB. Customer decided that they didn’t want to spend money on getting it resolved which was understandable.
At least they went for an ISE instead! 8)
