What does the error E15 mean on a Baxi boiler?

Error E15 on a Baxi boiler indicates a gas valve command fault where the valve is not responding correctly. 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. Do not attempt to operate the boiler. Contact a Gas Safe registered engineer to diagnose whether the valve, wiring, or control board is faulty.

What does the error E384 or 164 mean on a Baxi boiler?

Error E384 or 164 on a Baxi boiler indicates false flame detection when there should be no flame. 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 safety concern requiring professional inspection. Do not attempt to operate the boiler. Contact a Gas Safe registered engineer to check the ionisation electrode.

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.01.08 mean on a Baxi boiler?

Error H.01.08 on a Baxi boiler indicates the flow temperature is increasing too quickly in heating mode, causing a temporary stoppage of 10 minutes. This suggests a circulation problem. Check for closed valves or airlocks. The boiler should reset automatically. Contact a heating engineer if it recurs frequently.

What does the error E10 mean on a Baxi boiler?

Error E10 on a Baxi boiler indicates an external probe fault, typically the outdoor temperature sensor. Contact a heating engineer to check and replace the sensor if faulty.

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).

How does a Baxi air source heat pump work?

A Baxi air source heat pump takes heat from the outside air and boosts it to a higher temperature using a compressor, then transfers the heat to your home's heating system. It works like a refrigerator in reverse, with a fan drawing ambient air into the evaporator where refrigerant absorbs the heat.

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.

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 the difference between a vented and unvented cylinder?

A vented cylinder draws cold water from a storage tank in the loft and relies on gravity to feed water into the cylinder. An unvented cylinder connects directly to the mains water supply, eliminating the need for a loft tank and delivering hot water at mains pressure.
