    British Gas RD532 no power to fan. This is a Greenstar Worcester Bosch product.

    Hi, all lights showing things good. Water pressure good. Pump running continuously on switch on. Fan not rotating but if I spin it by hand it seems free. Sometimes the code C1 comes up which is fan, but on checking there is no power from the circuit board to the fan connection. Any ideas please?
