Baxi Appliance Repair in Heatons North

What does the error E50 mean on a Baxi boiler?

Error E50 on a Baxi boiler indicates a domestic hot water temperature sensor fault. Contact a Gas Safe registered engineer to diagnose and replace the faulty sensor.

What does the error A.02.06 mean on a Baxi boiler?

Error A.02.06 on a Baxi boiler indicates low system pressure in the heating circuit. Switch off the boiler before repressurising. Use the filling loop to add water until pressure reaches between 1 and 1.5 bar, then switch the boiler back on. If you need to top up frequently, have a heating engineer check for leaks.

What does the error E.04.17 mean on a Baxi boiler?

Error E.04.17 on a Baxi boiler indicates a fault in the gas valve control circuit. 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 reset or operate the boiler until professionally inspected. Contact a Gas Safe registered engineer immediately.

What does the error E.01.04 mean on a Baxi boiler?

Error E.01.04 on a Baxi boiler indicates flame loss has been detected five or more times in 24 hours. 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 pattern of repeated flame loss requires professional diagnosis. Contact a Gas Safe registered engineer.

What does the error E317 or 162 mean on a Baxi boiler?

Error E317 or 162 on a Baxi boiler indicates the wrong power supply electrical frequency. The boiler expects 50Hz mains power. Check if there are issues with your electrical supply. Contact an electrician if mains power is unstable, or a heating engineer to inspect the boiler.

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.

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.

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.

What should I do if my Baxi boiler condensate pipe is frozen?

If your boiler shows error code E133 or E28 and has stopped working in below zero temperatures, your condensate pipe may be frozen. Locate the frozen section, thaw it with warm water using a hot water bottle, microwaveable heat pack, or watering can, then reset the boiler.

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.
