Baxi 600 Boiler PCB Fault Repaired in Yardley Wood, Birmingham
Boiler repair experts in Birmingham
We were recently called out to a boiler repair in Yardley Wood, Birmingham, where a homeowner had completely lost heating and hot water. The boiler in question was a Baxi 600, and the symptoms pointed very clearly towards an electrical fault rather than a gas or pressure issue.
This job was carried out just off Yardley Wood Road, close to the well-known Billesley Common, a popular local landmark in the area.
Boiler Symptoms: Blank Screen but Fan Running
When we arrived, the homeowner explained that the boiler had stopped working suddenly. On inspection, we found:
- Boiler display completely blank
- Fan running constantly
- No ignition or heat demand response
- Correct mains power present at the boiler
These symptoms are classic signs of a PCB (printed circuit board) fault. The boiler had power going into it, but the control board was failing to initialise the system properly.
Diagnosing the PCB Fault
After confirming:
- Incoming voltage was correct
- Fuse and external controls were working
- No fault codes could be displayed due to the blank screen
We isolated the issue to the main circuit board. This is a known failure point on many modern boilers, including the Baxi 600, especially if the boiler hasn’t been serviced regularly.
Temporary Repair: Warming the PCB
To get the customer safely back up and running while we sourced the correct replacement part, we carried out a temporary repair.
By carefully warming the PCB using a hairdryer, the board briefly came back to life:
- The display returned
- The boiler fired correctly
- Heating and hot water were restored
This confirmed 100 percent that the PCB was failing internally. While this method is not a permanent fix, it’s a useful diagnostic and short-term solution to keep customers warm in an emergency.

Once the fault was confirmed, we ordered a new genuine replacement PCB for the Baxi 600. On the return visit, the circuit board was replaced, tested, and commissioned correctly, restoring full and reliable boiler operation.
Why It’s So Important to Get an Annual Boiler Service
This fault could potentially have been picked up earlier with a Boiler Service Birmingham. During an annual service, we:
- Check electrical components and connections
- Inspect the PCB for early signs of failure
- Test boiler operation under load
