My Bosch washing machine WFOP2467GB will not spin at the end of the cycle. It fills on all cycles and drains when set to Drain. When set to Spin the pump runs to drain the machine but the drum does not turn. During the wash cycle the drum does not turn. The belt on the drum is serviceable / okay and is fitted correctly. The pump drain chamber is free from blockages. Any ideas please?
