Ok not good news im afraid. If the washer completes the test cycle ok ie drum turns one way then the other then spins and then fills ok and drains then all this can be is a faulty control board.
Ive replaced loads of these over the years for fault like this were the test cycle works fine but normal mode doesn't. All this can be is down to the control board as by running the test cycle this proves all the componments in there work fine as that's what the test cycle does.
So to cure this the control board itself will need to be replaced and that will get it up and running again.
If you need anymore info just get back to me.
Oh dear, that doesn't sound good. How much do you think that might end up costing?
The control board itself is about £55 but if you are getting someone in to do it you can add another £50 on top of that.
