Bosch WF02466GB – Heating problem

Hi Folks

Orig went to this because it was restarting program but when I tested it, it was sticking on wash program while counting down and hanging at 1min then restarting.

Tested heater and all seemed fine – even checked to make sure it was heating but earth res on motor low and know this can cause probs with timing. Clearned end frame etc and all ok.

Cust phone and still playing up so asked her to do some wash tests as seemed intermitant.

30deg wash ok any higher than 40deg then sticks on wash while countin down again.

It would appear from what she says that the m/c is not getting up to temp altho the heater comes on and warms the water to about 30deg whatever the program. So looks like either heater or board might be breaking down after m/c been on for a while.

Anyone else had this problem – seems unlikely the heater breaking down in my xp so is it more likely to be board? Posibly NTC altho I would have thought this would have brought up an error code?

Any help or advise welcomed before a return visit.

Thanks

Mick
