Bosch WAQ243 stops when attempting full spin after brush replacement

The problem

After the carbon brushes were replaced on a Bosch WAQ243, the machine spun correctly for the first couple of uses but then began trying to enter full spin and stopping repeatedly, similar to an out-of-balance condition, even when empty.

Likely cause

Most strongly supported diagnosis is a motor brush issue after fitting: the brushes may be charred, sticking, or not making good contact with the commutator. A poor motor plug connection was also suggested. Exact cause was not confirmed.

What fixed it

Recommended action was to remove the brushes fully and check that they are not charred or sticking and that they are making good contact with a shiny commutator. The motor plug should also be checked. It was also suggested to try a normal laundry load in case the machine behaves differently than when empty. No confirmed repair result was posted.

Checks to try

• Removed and rechecked the brushes
• Check whether the brushes are charred or sticking
• Check that the brushes are making good contact with the commutator
• Check the motor plug
• Try the machine with a normal load of laundry
