What it is
The Baxi 7810673 is a cartridge for a three-way valve, supplied complete with O-rings. It sits inside the diverter valve assembly on Baxi 224 and 228 Combi 2 appliances and controls the changeover between domestic hot water and central heating. The cartridge is the moving element that directs flow to the correct circuit as the valve is actuated.
Signs this part needs replacing
- Domestic hot water runs cold or fluctuates while the heating is off
- Radiators heat up when only hot water is demanded
- No hot water draw-off despite the boiler firing
- Water weeping from the valve body around the cartridge spindle
- Diverter valve sticking or failing to change position between modes
Before you order
- Confirm your appliance model against the fit list above
- Check the GC number on the appliance data badge matches your model variant
- Inspect the valve body for damage or scale before fitting a new cartridge
- Confirm the existing cartridge is the three-way valve type and not a different valve component
