Baxi Appliance Repair in Southgate

What does the error E385 or 165 mean on a Baxi boiler?

Error E385 or 165 on a Baxi boiler indicates the electrical supply voltage is too low. Check if other electrical appliances work correctly. If mains power appears normal, contact a heating engineer to inspect the boiler's electrical components.

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 E135 mean on a Baxi boiler?

Error E135 on a Baxi boiler indicates an internal error with the control system. Try resetting the boiler. If the error persists, contact a Gas Safe registered engineer as the PCB or other internal components may need inspection.

What does the error H.01.05 mean on a Baxi boiler?

Error H.01.05 on a Baxi boiler indicates the maximum temperature difference between flow and return has been reached. This suggests a circulation problem. Switch off the boiler. Check for closed valves, airlocks, or blocked radiators. Contact a heating engineer if the fault persists.

What does the error E09 mean on a Baxi boiler?

Error E09 on a Baxi boiler indicates a gas valve connection fault. 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 inspect the connections and gas valve.

How does a Baxi combi boiler work?

A Baxi combi boiler combines heating and hot water delivery in one compact unit. When the room temperature drops below the thermostat setting, the boiler heats the central heating system. When a hot water tap is turned on, a valve inside the boiler diverts heat to the domestic hot water supply until the tap is turned off.

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.

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.

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.

When should I replace my Baxi boiler?

A Baxi boiler typically has an average lifespan of around 10 to 15 years, depending on how well it is maintained. Regular servicing helps the boiler reach the higher end of its lifespan.
