When to replace boiler parts
Because the boiler heats and holds your water, and its heating elements, probes and seals are critical to stable temperature, these are parts owners replace regularly. We stock heating elements, gaskets and seals, level probes, safety valves and thermostats for this model. Typical signs it's time to order include a machine that won't heat, boiler leaks, tripping thermostats, or inconsistent temperature - all fixable at home with the right spare.

Fitment matters - parts are grouped by model to help you order the correct spare, but if you're unsure, contact our team with your machine details before you buy and we'll confirm the fit.
