Baxi Appliance Repair in Davenport & Cale Green

What does the error E430 or 166 mean on a Baxi boiler?

Error E430 or 166 on a Baxi boiler indicates a water pressure temporary fault or that the water pressure test has failed. Switch off the boiler and check system pressure using the pressure gauge. Repressurise if below 1 bar using the filling loop. Contact a heating engineer if the fault persists.

What does the error E.04.12 mean on a Baxi boiler?

Error E.04.12 on a Baxi boiler indicates a flame monitoring failure where the expected flame was not detected. If you smell gas, do not operate any electrical switches, ventilate the area if safe to do so, leave the property, and call the gas emergency line from outside. Contact a Gas Safe registered engineer to inspect the ionisation electrode and ignition system.

What does the error E130 mean on a Baxi boiler?

Error E130 on a Baxi boiler indicates the flue thermostat has tripped due to high flue gas temperatures. Switch off the boiler immediately. If you smell gas, do not operate any electrical switches, ventilate the area if safe to do so, leave the property, and call the gas emergency line from outside. This is a serious safety issue. Do not attempt to reset or operate the boiler. Contact a Gas Safe registered engineer to inspect the flue, combustion, and heat exchanger.

What does the error H.03.05 mean on a Baxi boiler?

Error H.03.05 on a Baxi boiler indicates the power supply voltage is too low. Check if other electrical appliances are working correctly. If the mains power appears unstable, contact an electrician. If power is normal, contact a heating engineer to inspect the boiler.

What does the error E.04.01 mean on a Baxi boiler?

Error E.04.01 on a Baxi boiler indicates the flow temperature sensor is short circuited. Contact a Gas Safe registered engineer to test and replace the sensor if faulty.

Why does my Baxi boiler keep losing pressure?

Common causes of pressure loss include small water leaks in the heating system, bleeding radiators (which releases water), or recent maintenance work. Some pressure loss over time is normal, but if you need to repressurise frequently, contact a Gas Safe registered engineer to investigate.

What is a condensing boiler?

A condensing boiler is a high-efficiency boiler that captures and reuses heat from the flue gases that would otherwise be lost. All modern Baxi boilers are condensing boilers. The technology uses larger heat exchangers to recover almost all the heat, reducing fuel consumption and emissions.

How do I reset my Baxi boiler?

The reset method depends on your boiler model. For boilers with a dedicated reset button, press and hold until the red lockout light goes out. For boilers with a thermostat control knob, turn it fully anticlockwise and hold until the light goes out. For boilers with a selector switch, turn to the R (Reset) position and hold for at least 5 seconds.

How efficient are Baxi air source heat pumps?

Baxi air source heat pumps are generally 300 to 400% efficient. This is measured as Coefficient of Performance (COP), meaning the heat pump can create three to four units of energy for every one unit of electricity it uses.

Do I need a cylinder with a Baxi heat pump?

Yes, Baxi air source heat pumps require a hot water cylinder as they do not provide instant hot water like a combi boiler. The Baxi ASHP cylinders are designed specifically for use with heat pumps and feature larger coils for better heat transfer at lower flow temperatures.
