Hiya,

Sorry for the delay in getting to your question.

 

If you still need help with this, can you advise, does it do this in the wash cycle and the spin only cycle?

 

Thanks

Hi it happans in every mod as soon as you start m/c when it should be in slow mod

Expert:  Techdesk replied 4 years ago.

Hiya,

There are a few causes of this problem.

 

It's a fault on the tachometer circuit of the motor.

The problem can be the motor, control board, the wires to the tachometer or the connection at the control board.

 

Unplug the appliance.

Take the rear panel off and gain access to the motor and motor wiring.

(You'll need torx drivers or bits for the screws).

Check the thin wires at the far end of the motor (not the belt end) and see if they have broken or if the tachometer magnet has come out.

Check the wires at the motor plug corresponding to the thin ones.

Check the same at the control board (you'll need the top off to check the facia board).

 

If all appears ok, you have a fault with the motor and/or control board.

 

Obviously, if you cannot do the work yourself, you'll need to get someone else to do it for you.

 

Hope this helps

Thanks

Thanks is the control board the large curcit printed board on top of the m/c with all the wires coming from it

Hiya,

Yes, but do check for another board at the bottom.

Some machines have 2, most only have the 1.

 

Thanks
