What it is
The Baxi 231711BAX is a printed circuit board kit intended for Baxi Solo PF 2, Solo 2 and Solo 3 appliances. The board is the control centre of the appliance: it sequences ignition, runs the fan and pump, regulates temperature and enforces the safety interlocks that shut the appliance down when a fault is detected. It is supplied as a kit rather than a bare board, so the replacement covers the control assembly as specified by the manufacturer for these Solo variants.
Signs this part needs replacing
- The appliance fails to fire, or locks out without a clear fault indication
- No heating or hot water even though the programmer or thermostat is calling
- The fan, pump or other controlled component does not run when demanded
- Intermittent running, unexplained shutdowns or repeated lockouts
- Visible scorching, burn marks, corrosion or bulging capacitors on the board
Before you order
- Check the GC number and serial plate on the appliance to confirm the exact Solo variant.
- Match the part number 231711BAX against the number printed on the board being replaced.
- PCB kits can need appliance-specific settings or parameter checks after fitting; follow the manufacturer's instructions for the model.
- Confirm whether a gasket or seal is required for the board cover on your appliance before starting the job.
