Baxi Appliance Repair in Exwick

What does the error E109 mean on a Baxi boiler?

Error E109 on a Baxi boiler indicates a pre-circulation alarm during the phase before ignition. Switch off the boiler and check system pressure. Repressurise if needed using the filling loop. Switch the boiler back on and ensure the pump is operating. Contact a heating engineer if the fault persists.

What does the error E125 mean on a Baxi boiler?

Error E125 on a Baxi boiler indicates a water circulation problem in the primary heating circuit. Switch off the boiler before bleeding radiators. Bleed your radiators to release trapped air and check system pressure afterwards. Switch the boiler back on and ensure the heating pump is running. If the fault persists, contact a heating engineer.

What does the error E134 mean on a Baxi boiler?

Error E134 on a Baxi boiler indicates the gas valve has been open too long without gas flowing. 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. If there is no gas smell, check your gas supply is on and that other gas appliances work. Contact a Gas Safe registered engineer immediately.

What does the error E118 mean on a Baxi boiler?

Error E118 on a Baxi boiler indicates low water pressure below 0.5 bar. Switch off the boiler before repressurising. Use the filling loop to repressurise the system to between 1 and 2 bar, then switch the boiler back on. If the boiler loses pressure repeatedly, contact a heating engineer to check for leaks.

What does the error E28 mean on a Baxi boiler?

Error E28 on a Baxi boiler indicates a flue temperature sensor fault, blocked flue, or frozen condensate pipe. In cold weather, check and thaw the condensate pipe first. If the error persists, contact a Gas Safe registered engineer.

What is the ideal pressure for a Baxi boiler?

The ideal pressure for a Baxi boiler is between 1 and 2 bar when the system is cold. A pressure reading in this range ensures the boiler operates efficiently and safely.

What is the difference between a direct and indirect cylinder?

An indirect cylinder gets heat from an external source such as a boiler, with heated water circulating through a coil inside the cylinder. A direct cylinder has its own built-in immersion heater and heats water directly using electricity.

What are the different types of Baxi boilers?

Baxi offers three main types of boilers: combi boilers (which provide heating and hot water on demand without requiring a cylinder or tanks), system boilers (which include the expansion vessel and pump but require a hot water cylinder), and heat-only boilers (which require both a cylinder and cold water tanks in the loft).

Can a Baxi heat pump work alongside a boiler?

Yes, a Baxi air source heat pump can work alongside a boiler in what is called a hybrid system. The boiler provides supplementary heating during extreme cold weather, temperature delays, legionella cycles, or if there are any issues with the heat pump.

Are Baxi heat pumps noisy?

Baxi heat pumps typically reach 60 to 65 decibels at maximum operation, which is comparable to people conversing in a room. Maximum noise occurs only during extreme cold weather; units run quieter under normal conditions.
