What does E125 mean on a Baxi boiler?
Baxi brand boilers are common in many commercial and residential buildings throughout the UK. As such, both gas safe engineers and homeowners should be aware of the error codes that can appear on these boilers along with the causes. Below we break down exactly what the E125 message on a Baxi boiler means.
How to spot an error code on a Baxi boiler
Most Baxi boilers have a digital screen that will display information about the unit. This will include readings such as water temperature to taps and radiators, boiler pressure, and boiler error codes. Depending on the model of boiler, an error or fault code may be accompanied by a flashing-coloured light.
What the 125-error code means on a Baxi boiler and how to fix it
An E125 fault code on a Baxi boiler appears due to an issue with the circulation resulting from low pressure within the system. It’s possible for this problem to be solved by topping up the pressure of the boiler. However, if there’s a more serious issue causing the boiler to lose pressure continuously, it may be necessary to seek out parts and spares or a Baxi boiler repair service.
An E125 code can have a number of different causes and as addressing the cause of the error often leads to the resolution of the problem, understanding these potential causes can be essential in fixing the boiler. Low Baxi boiler pressure is most commonly caused by:
- Leaks due to damage to the unit or internal components.
- Air releasing from the radiators during bleeding.
- Faulty pump.
- Pipe blockage due to limescale, debris, or freezing.
In the case of a leak or a faulty component, baxi boiler replacement parts may be needed to guarantee that pressure can be restored to the boiler and by extension, circulation can also be restored. This is because corrosion and wear can occur over time, regardless of how well maintained the boiler is.
You can use the display to check that the necessary pressure level has been restored. Once this is confirmed, you may have to reset the boiler for the E125 error code to disappear and the boiler to return to its regular functionality. This is simply because most error codes are triggered as a safety mechanism to prevent potential damage to the unit or the individual.
