hi all can anyone help me with a service wm its 12 months old and the isn’t anything working not even the power light.

I’ve changed the board for a new one checked the looms on/off switch solenoids supressor and motor even the pump i cant find a thing wrong with it.

im told that its a neutral fed machine???? what does that mean?

the insulation on the machine was

any clues people i would appreciate it guys

Re: service

I feel a bit silly suggesting this but you didn’t say, so what about wall socket, plug, mains cable and interlock?

Re: service

as has been said model no ,also do you have supply on the machine side of the suppressor ?.
If so maybe door lock but from memory the lights should still come on

Re: Servis

was there any damage visible on original pcb?also the small top pcbs can fail on these giving this fault as well.

Re: Servis

i had this if the machine is dead no power.
i spoke to an engineer who did contract work for servis.He told me to repair R1 or R2 on the control panel.It worked for me

Re: Servis

oh yeah i checked the plug it wasn’t molded.
i had 230 from the suppressor and i put a new door lock on first thing.
i had 240 to the board and from the board i didnt check the display board as i didnt
think that would effect the machine being completely dead.
i think it was a servis m 6614 i was assisting on it.

You didn’t answer robinsonrobo’s question though. 😕 : –

Any visible damage on the power board you changed would almost certainly cause damage to the programme board as well. Especially so if there’s damaged tracks associated to the motor. 😉

R1 and R2 are the main resistors on that board and if either was faulty on the old board they surely can be OK on the new one you fitted so I wouldn’t concern yourself over that issue. Clearly not the fault in this case I shouldn’t think?

Neutral fed machine means that it’s components are fed directly back to neutral and therefore only switched on the live side. (IIRC?)

HTH?:D

[craigmossom]

aahhhh i see!!!
no not a thing visable on the old board no tracks or burns on the board i checked for lose wires on all the looms too and connection blocks.
i did an insulation test e-l e-n and got 350M ohm

Can’t say I’ve heard the expression but I have heard of machines “switched in neutral” meaning the opposite of having all the switches on the live side, which I think is the usual way of doing things; although these days who knows?

Re: Servis

Be sure to check all the usual places,what i mean is, i went to a dishwasher ( aeg ) last week, customer said it hasnt worked since 2003 when they moved in, although she told me the last tenant assured her it was working .

First thing i checked was the fuse spare associated with it, there was no fuse in, put in a fuse machine worked fine.
“dam” she said “i been washing up for the last six year for the sake of a fuse”.

[craigmossom]

haha that s priceless i did check all the obvious stuff just couldn’t see what it was.

it was probably staring me in the face all the time though cheers for all your help people
