Boilers: Boiler parts and spares Baxi spares
If you've got a faulty Baxi boiler, don't attempt to fix the problem or replace a part yourself. You'll need to contact a qualified boiler engineer to replace faulty boiler parts and get it back up and running again.
You shouldn't attempt to remove the outer casing of your boiler to take a look at what's wrong, so you won't know what the problem is, or what parts you might need - your boiler engineer will be able to tell you which spare parts your Baxi boiler requires when they come to inspect it.
It may prove difficult to order spare parts for your boiler yourself because customer spare parts outlets and online stores like Espares or Partmaster don't sell boiler spares, while several other boiler spares outlets are for trade use only. Interpart is the official Baxi spare parts stockist, supplying the industry with Baxi spares and parts. While they do not sell parts directly to members of the public, you can call their enquiry line on 0844 871 1540 if you have a Baxi parts-related question.
In most cases a boiler engineer will obtain or order the correct Baxi boiler spare or part to fix your boiler for you. Ask for a breakdown of the spare parts your engineer is ordering, and their respective costs including VAT, or ask to see the product catalogue they're ordering from to ensure you're getting a fair rate on the spare parts.
It might also help to consult your Baxi boiler manual for troubleshooting information, or to look up product specifications on the Baxi website.
