What it is
The Baxi 7822511 is a PWM adapter intended for use with Wilo pumps fitted to Baxi heating appliances. It provides the pulse-width modulation control link between the boiler's control electronics and the pump, allowing pump speed to be regulated in line with demand. It is supplied as a single adapter component.
Signs this part needs replacing
- The pump runs at a fixed speed and does not modulate with demand
- Boiler displays a pump or circulation-related fault code
- Pump speed control faults appear intermittently or after the boiler warms up
- The adapter shows signs of heat damage, corrosion or a damaged connector
- Pump operation is erratic despite the pump itself testing correctly
Before you order
- Confirm your appliance model appears in the fit list above
- Check that the pump fitted to your appliance is a Wilo unit
- Verify the existing adapter part number matches 7822511
- Inspect the wiring and connectors before replacing the adapter alone
