What it is
The Baxi 5118390 is a wiring harness (catalogue type: wiring) for Baxi gas boilers. It groups the electrical connections for the 3-way valve, pump and gas valve into a single assembly, supplying power and control signals between the boiler's PCB and these components.
Before you order
- Check the boiler model and, for Combi A and Platinum-range models, the serial number, as fitment varies before and after the stated serial numbers.
- Confirm the boiler is listed above before ordering.
- Isolate the boiler from the electrical supply before any work on the wiring.
