Keston Appliance Repair in Newnham

What does error F2 mean on a Keston S30 boiler?

Error F2 on a Keston S30 boiler indicates flame loss during operation. If you smell gas, do not operate any switches or appliances, ventilate the area if safe to do so, evacuate the property, and call the gas emergency services from outside. Otherwise, check if the condensate pipe is frozen and thaw if necessary. Try resetting the boiler. If the fault recurs, contact a Gas Safe registered engineer.

What does error E02 mean on a Keston Qudos boiler?

Error E02 on a Keston Qudos boiler indicates ignition failure after five attempts. If you smell gas, do not operate any switches or appliances, ventilate the area if safe to do so, evacuate the property, and call the gas emergency services from outside. Otherwise, check that gas supply is on, the flue terminal is clear, and the condensate pipe is not blocked. Try resetting the boiler. If the fault persists, contact a Gas Safe registered engineer.

What does error E01 mean on a Keston C36 boiler?

Error E01 on a Keston C36 boiler indicates ignition failure - the boiler has attempted to ignite five times without success. If you smell gas, do not operate any switches or appliances, ventilate the area if safe to do so, evacuate the property, and call the gas emergency services from outside. Otherwise, check that your gas supply is on and try resetting the boiler. If the error persists, contact a Gas Safe registered engineer.

What does error E37 mean on a Keston C36 boiler?

Error E37 on a Keston C36 boiler indicates low water pressure. Use the filling loop to repressurise the system to approximately 1.2 bar. If pressure drops repeatedly, check for leaks and contact an engineer.

What does error E67 mean on a Keston Qudos boiler?

Error E67 on a Keston Qudos boiler indicates low water pressure below 0.4 bar. Use the filling loop to repressurise the system to approximately 1.2 bar. If pressure drops repeatedly, check for leaks and contact an engineer.

Why are my radiators cold when my Keston boiler is running?

The most common causes are low boiler pressure, trapped air in the radiators, stuck thermostatic radiator valves, a faulty circulation pump, or sludge buildup. Check the pressure gauge first and repressurise if below 1.0 bar. Then try bleeding the radiators to release trapped air.

What is checked during a Keston boiler service?

A Gas Safe engineer will inspect for corrosion and leaks, check the flame burns blue, examine flue terminals and seals, test gas pressure and flow settings, check the expansion vessel pressure, clean the burners, and inspect all key components for wear. The boiler is also tested operationally.

What is a Keston magnetic system filter and do I need one?

A Keston magnetic system filter protects your boiler by capturing sludge, debris, and magnetic contaminants from the heating system. Installing a Keston 22mm System Filter with a Combi or System boiler extends the warranty from 5 to 7 years. The filter should be cleaned during annual servicing. It is fitted on the return pipe close to the boiler.

Why does my Keston combi boiler preheat periodically?

Keston combi boilers have a preheat function that fires the boiler briefly, approximately every 90 minutes, to keep water in the hot water calorifier warm. This reduces waiting time for hot water at the tap. If the boiler is installed in a bedroom or noise-sensitive area, the preheat function can be switched off using the preheat switch on the boiler.

How often should my Keston boiler be serviced?

Keston boilers should be serviced annually by a Gas Safe registered engineer. This annual service maintains operational efficiency and safety. The best time to arrange a service is during summer when engineers are less busy.
