Baxi 800, 600, and Duo-tec: Common Parts We Stock
For the more current Baxi 800, 600, and Duo-tec combi ranges, common failure components are usually readily available. These include parts addressing frequent issues like E119 low pressure (often a pressure relief valve or expansion vessel issue) or E133 ignition failure. We routinely carry Baxi fans, NTC sensors, PRVs (pressure relief valves), and expansion vessels on the van. This allows for efficient diagnosis and often, a first-visit repair.
- Fans, NTC sensors: common wear items
- PRVs, expansion vessels: address pressure issues
- Kept in stock for newer Baxi ranges
