1) What is a Worcester boiler PCB?
A PCB (Printed Circuit Board) is the boiler’s main control board. It manages key functions like ignition, fan operation, pump control, heating and hot water demand, and safety monitoring.
2) Which Worcester models do you supply PCBs for?
We stock PCBs for popular Worcester ranges including Greenstar, CDI, Ri, Si, Highflow and other compatible Worcester boilers.
3) What problems can a faulty Worcester PCB cause?
A failing PCB can lead to ignition failure, random lockouts, no heating or no hot water, fan/pump not running, temperature fluctuations, or recurring fault codes.
4) How do I know if my Worcester PCB needs replacing?
Common signs include repeated fault codes, intermittent operation, burning smell or visible damage on the board, the boiler not responding to demand, or the appliance cutting out without a clear mechanical cause. A qualified engineer should confirm the diagnosis.
5) Can replacing the PCB fix “no heating” or “no hot water” issues?
If the PCB is the root cause (not sensors, diverter valve, pump, or wiring), replacing it can restore normal operation. Proper fault-finding is important before ordering.
