Baxi boiler repair in London
We work on Baxi boilers, including the older and discontinued ranges many firms will not touch. We identify the model from the data badge, then read the fault against the manufacturer’s own manual.
That tells us what the fault actually is, and whether the part still exists. Sometimes the honest answer is that the appliance is not worth spending money on. We will say so.
What the Baxi manual says about these codes
A fault code narrows down where to look. It does not say which part has failed, and it does not decide whether a boiler is worth repairing.
| Model and fault | What it can mean | Manual source | Repair or replace? |
|---|---|---|---|
Baxi Bermuda BBU 15 HEE133
|
Interruption of the gas supply, failed ignition, or no flame detected. On this model a three digit code is shown split, so E133 appears as "E1" alternating with "33". |
Installation & Servicing Instructions, 2014, p. 36 [M] | Inspect first. Often the gas supply or the ignition, not the boiler. |
Baxi Bermuda BBU 15 HEE158
|
Condensate discharge system fault. | Installation & Servicing Instructions, 2014, p. 36 [M] | Assess the drain before anything else. A frozen or blocked pipe is common. |
Baxi Bermuda BBU 15 HEE125
|
Circulation fault in the primary circuit. The manual gives the trigger as the boiler exceeding the selected temperature by 25°C twice within two hours of the burner lighting. | Installation & Servicing Instructions, 2014, p. 36 [M] | Check circulation and the water in the system first. |
Baxi Bermuda BBU 15 HEE110
|
The primary water has overheated, or there is excess condensate in the sump. The manual limits the boiler to four resets in any five hour period. |
Installation & Servicing Instructions, 2014, p. 36 [M] | Assess the cause. The manual allows a reset, held for five seconds. |
No rows match that search.
Meanings come from the manufacturer manual. Repair guidance depends on inspection and on parts.
A code on its own cannot decide whether a boiler should be replaced.
