Baxi Appliance Repair in Reddish North

What does the error E110 mean on a Baxi boiler?

Error E110 on a Baxi boiler indicates overheating or safety thermostat activation. Switch off the boiler immediately and allow it to cool completely for at least 30 minutes. Once cooled, bleed radiators to release any trapped air and check system pressure. Reset the boiler and contact a Gas Safe registered engineer if the error recurs.

What does the error H.01.18 mean on a Baxi boiler?

Error H.01.18 on a Baxi boiler indicates no water circulation has been detected temporarily. The boiler should attempt to recover automatically. If the error persists, switch off the boiler, check system pressure, and bleed radiators. Contact a heating engineer if the fault continues.

What does the error H.02.07 mean on a Baxi boiler?

Error H.02.07 on a Baxi boiler indicates persistent low pressure in the heating circuit. Switch off the boiler before repressurising. Repressurise the system using the filling loop and inspect visible pipework for leaks. A heating engineer should investigate if the problem recurs.

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 E.04.08 mean on a Baxi boiler?

Error E.04.08 on a Baxi boiler indicates the maximum safe temperature value has been reached. Switch off the boiler immediately and allow it to cool completely for at least 30 minutes before attempting a reset. Check for circulation issues such as closed valves or airlocks. Contact a heating engineer if the fault recurs.

Do I need to change my radiators for a Baxi heat pump?

Most radiators in homes today are sized for 80°C boiler flow temperatures. Since heat pumps operate at lower flow temperatures of around 50 to 55°C, radiators may need to be enlarged to deliver the same heat output.

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 repressurise my Baxi boiler?

To repressurise a Baxi boiler, locate the filling loop (usually a flexible silver or chrome pipe beneath the boiler with valves at each end), open both valves slowly while watching the pressure gauge, stop when pressure reaches 1 to 1.5 bar, then close both valves securely.

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).

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.
