The machine is empty now and has been powered off but still it will not run, any ideas on how to resolve it, is it a switch or something??

bit confused, when you turn it on does it fill with water does it wash and when on spin mode does the drum go round if it dont go round then i would look at the brushes on the motor .

chris25 · Posted: Tue Nov 03, 2009 9:17 pm Post Subject:

on a wash cycle The machine begins to fill with water carries out a few revolutions of the drum then stops with lamps lit.

on a spin the machine drains then rotates the drum for a couple of revolutions then faults,

i have checked the brushes and they are o.k, the motor is only 9 months old!!

Hi
I've changed the board on my WMA 37 this afternoon, found the cable s between the motor and the board have worn away against the concrete block. The machine now does 4 spins then it goes straight to End Light comes on. On every program The diagnosis code is

A B C D
on on off off

Start butt pressed with door open.......off..........on............off........off
or O/C interlock.

What does this mean other than more expense?

the cables have shorted together can you rejoin them .choc block will be good from halfords. they are 4 white ones you need to match the right ones up not to difficult.

chris25 · Posted: Sat Nov 07, 2009 4:25 pm Post Subject:

yeah i done that repaired the cables and changed to the new board,but board people mention change the interlock??? Would this be the door interlock?

Tried the machine and instead of two revolutions now does 4??? then end light comes on.

Fault code A B C D as last post.
