The Homecure team use a variety of techniques and tools when conducting a Worcester Bosch repair. For example, if your Worcester Greenstar 30CDi Combi is experiencing intermittent water, we check the heat exchanger while running the hot tap, which will help us assess if the exchanger needs replacing. Or, for faulty fans on a Worcester 532i, the voltage power between the brown and purple wires is checked. The Homecure team always choose the safest and most cost-effective option so you get the best results.
