What it is
The Baxi 7842891 is a Wilo pump assembly supplied as a pump spares kit for Baxi gas appliances. The pump circulates primary water around the heating circuit and through the domestic hot water heat exchanger on combi models. It is fitted across a number of Baxi Assure, DUO-TEC Compact, Megaflo Compact and Platinum Compact appliances.
Signs this part needs replacing
- Grinding, whining or rumbling noise from the pump body during operation
- Boiler fires and reaches temperature but radiators stay cold, indicating poor circulation
- Boiler repeatedly overheats, cycles or locks out on a circulation-related fault
- Pump runs hot, seizes, or fails to turn when the heating demand is present
- No domestic hot water on combi models where the pump drives the secondary circuit
Before you order
- Confirm your appliance model and GC number against the fit list above
- Check the existing pump is a Wilo unit and matches the assembly being replaced
- Isolate the electrical supply and shut off the water before removing the old pump
- Check the pump head, seals and connections for condition before fitting
