What it is
The Ariston 65121083 is a wiring microswitch used on the central heating and domestic hot water circuits of Ariston Genus 30 MFFI UK boilers. It switches the low-voltage control signal that tells the boiler when heating or hot water is being called for. It is a serviceable electrical component, supplied as a single switch.
Signs this part needs replacing
- Heating or hot water fails to fire even though the programmer or thermostat is calling
- Boiler does not respond when the CH or DHW switch is operated
- Intermittent firing, with the boiler cutting in and out without a clear pattern
- No continuity across the switch when the actuator is depressed
- Burnt, pitted or discoloured contacts inside the switch body
Before you order
- Check the boiler model and serial number against the fitment list above, as serial number ranges apply
- Confirm which circuit the faulty switch serves, CH or DHW, before ordering
- Inspect the wiring and connector for damage before fitting a new switch
- Isolate the electrical supply before carrying out any work on the boiler
