Baxi strip-down service

Baxi boilers have a fan and burner assembly mounted on the heat exchanger, a condensate trap below, and an ignition and detection electrode. This is what our Gas Safe engineers do on a Baxi strip-down service. It covers Baxi 400, 600 and 800 combis, Duo-tec and Platinum boilers.

Step by step

1. Isolate and open up. Turn off the gas, power and water, remove the case and read any stored error codes.
2. Remove fan and burner. Disconnect the gas supply and electrics and remove the fan and burner assembly.
3. Inspect burner and seals. Check the burner, the burner seal and the heat exchanger door seal. Damaged seals are renewed.
4. Clean the heat exchanger. Clean the combustion side of the heat exchanger to remove deposits.
5. Clean the condensate trap. Remove, clean and refill the trap. Blocked traps are a common cause of Baxi lockouts.
6. Check the electrode. Inspect the ignition and detection electrode, check the gap and renew it if worn.
7. Rebuild and test. Reassemble, gas tightness test, and flue gas analysis to Baxi’s limits.
8. Final checks. Check the expansion vessel, system pressure, diverter valve operation and controls.

Price

A Baxi strip-down service is £175, or £260 with a landlord gas safety certificate on the same visit. If a seal, gasket or electrode needs renewing, we tell you the price before fitting it.
