Hi,
The HW Demand / Burner On lights do not illuminate on the Worcester Bosch 28CDi and it does not "fire up" when there is demand for DHW. With the hot tap fully open there is not even a drop of water from the tap. The heating is working fine however?
I would be grateful if someone could suggest how I could troubleshoot this problem. Is it likely to be the Flow Switch or Diverter Valve ( )
