Zanussi zwg1140m

[Lochgilphead]

My Zanussi washing machine ZWG1140M stops after a few minutes into the cycle. I have checked the heater, inlet solenoid and the pressure switch with a multi meter and all appear to be working. Could it therefore be the PCB?

stops and does what

light go out ?
lights flash ? if yes does it flash a sequence ?

Thanks for your reply, Dave. The machine stops, the lights go out, there is no error code. I

if all the light go out it sounds like the power supply for the electronics on the control board is faulty. Had a bosch machine doing the same thing about 3 months ago
if you turn if off at the wall does it come back on again and start where it left off. Only to fail again shortly after ?

No it doesn’t come back automatically. We can switch it to drain but that’s all. We have tried different wash cycles but it stops and blacks out between 8 and 20 minutes.
I can’t even find another PCB apart from Amazon and their price is £216. We will be better buying a new machine at that price.

Thank you for taking time to help and advise.

well its a pity as it seems the firms that used to do these sort of repairs seem to have gone

I know what is probably wrong with the board but you would have to be able to solder surface mount components

if you think you can or know someone who can let me know

Thanks, Dave. Tomorrow I am going to take out the board to see if I can see anything that is obviously at fault but for me it will be like shooting in the dark, but I’ve nothing to loose. I hate consigning this to the scrap heap because we have looked after this machine and it’s still in beautiful condition.
If you feel you can help further then I will be very grateful indeed.

i am fairly certain its the power supply chip
its a 7 leg chip soldered onto the board
there will not be any sign of failure but its very likely its gone

on top of that they are very cheap so well worth a go if you think you can do it

I’ll have a bash at it, Dave, it’s all I can do. I may get in touch with you tomorrow if thats okay.

no probs
if i am here will see your posts

I have the board off and it looks somewhat daunting! The only 7 leg chip that I can see is numbered j10 with the letters OP at the side of it. This is to the extreme left of the board away from what I assume is the mains power input. I’m not at all sure if this is the one you mentioned.

post a pic of the board

you will probably have to host it on an external site and post a public link due to space problems

normally the power chip are lnk*** or tny***

look up a pic of LNK264 on google [h=2][/h] Dave

[Lochgilphead]

There appears to be 5 of these components, small black boxes, 4 of them numbered G5lA-1 and 1 numbered HF33​​​​​​F but none with the prefix that you mentioned. If these are the power chips can I somehow test them with a multi meter?

Dave.

[electrofix]

assume you have looked on both sides of the board as seen a lot of zanussi’s where the power chip is on the other side of the board

will need to see a pic as all the pics of the board show it in a case

Dave,

I’m having the greatest difficulty uploading a photo to this site. I’ll keep trying.

Dave.
