What it is
The Vaillant 0020231142 is a pump motor used in a range of Vaillant gas boilers, including Home Combi, VUW, Ecofit and Ecotec models. It drives the boiler's circulating pump, which moves primary water around the heating circuit and through the domestic hot water plate heat exchanger. It is a serviceable component, so it can be renewed without replacing the complete pump assembly.
Signs this part needs replacing
- The pump runs hot, is noisy, or emits a humming or grinding sound during operation
- The boiler locks out or shows a pump-related fault code
- Poor or no circulation, with radiators heating unevenly or not at all
- The pump head does not turn when checked, or the motor fails to run when powered
- Repeated overheating or flow-related faults on the appliance
Before you order
- Confirm the appliance model and variant against the fit list above
- Check the existing pump motor part number on the component or in the manufacturer's parts list
- Verify the fault is with the motor rather than the pump head, PCB or wiring
- Isolate the appliance electrically and hydraulically before any work, and follow the manufacturer's instructions
