What it is
The Ariston 998583 is a fixing spring for the overheat thermostat used on Ariston gas boilers. It retains and seats the overheat thermostat against the heat exchanger surface so the thermostat can sense temperature correctly and trip when conditions demand. It is listed under thermostats within Ariston gas boiler spares.
Signs this part needs replacing
- The spring is corroded, distorted or has lost tension
- The overheat thermostat is loose or not seated squarely against its mounting face
- Repeated overheat lockouts after the thermostat has been checked
- The spring is missing or was not refitted during earlier service work
Before you order
- Confirm your boiler model and edition against the fit list above
- Check the overheat thermostat itself is serviceable before replacing the spring alone
- Inspect the mounting point for corrosion or damage that would prevent the spring seating correctly
