Technical Insight & Common Failure Symptoms

The Printed Circuit Board is a central electronic control component within the boiler. PCB-related problems require correct diagnosis, as similar symptoms can be caused by other electrical or boiler components.

Possible symptoms that may require investigation of the PCB or associated electrical system include:

• Boiler failing to operate or respond correctly

• Intermittent boiler operation

• Boiler failing to respond to heating demand

• Unexpected shutdowns or lockouts

• Electrical or control-related faults

These symptoms do not necessarily confirm a faulty PCB, as wiring, sensors, connections or other boiler components may cause similar issues. Correct fault diagnosis should be carried out before replacement.

Safety Advice

Boiler PCBs and other electrical control components should only be diagnosed, removed or installed by a suitably qualified and competent heating engineer.

Always isolate the electrical supply before carrying out any work and follow the manufacturer's installation and servicing instructions. Where work is carried out on a gas appliance, the appropriate safety checks must be completed before the boiler is returned to service.
