What it is
The Potterton 910026 is a water pressure switch kit used on Potterton gas boilers. It monitors water pressure within the appliance and signals the control system when pressure is present, allowing the boiler to run. This kit replaces earlier code 642235.
Signs this part needs replacing
- Boiler fails to fire on a hot water or heating demand despite the pump running
- Repeated low pressure faults or lockouts on the boiler display
- Intermittent ignition that clears when pressure is disturbed
- No burner operation when water pressure at the appliance is otherwise correct
- Fault traced to the pressure switch during diagnosis
Before you order
- Confirm your appliance model against the fit list above
- Check the control type where your model is listed with SIT or Honeywell controls
- Compare the existing switch and any code stamped on it with 910026 or 642235
- Isolate the electrical supply and water before fitting
