What it is
The Ariston 65116908-03 is a 5-metre head circulating pump with PWM speed control, manufactured by Ariston. It moves primary water around the heating circuit in condensing boilers and system appliances. It is used across the Alteas ONE, Cares ONE, CLAS ONE, Genus ONE and E-System ONE ranges.
Signs this part needs replacing
- The boiler runs but the heating circuit stays cold or heats unevenly
- Pump runs noisily, with grinding, humming or rattling from the pump body
- The appliance locks out or reports a pump-related fault code
- Radiators take far longer than normal to reach temperature
- The pump body is wet, weeping or shows signs of scale and debris build-up
Before you order
- Confirm the appliance model and GC number against the fit list above
- Check the fault code or diagnostic reading points to the pump rather than the PCB or sensor
- Verify the pump head and control type match the unit being replaced
- Isolate the appliance and drain down before removal
