Boiler Faults: FAQs for Installers

Combi boilers are designed to offer a rise in temperature depending on the flow rate passing through the boiler. As more hot water outlets are used, both the flow and temperature will be shared between the channels. 

In Winter, your condensate pipe may freeze and become blocked. This can easily be fixed by using a hot water bottle, or pouring warm water over the pipe itself. For more information on this check out our ‘How to’ video on YouTube. If the weather is milder it may be worth checking where the condense pipe terminates for blockages such as leaves. Usually, a gurgling noise can be heard from the boiler during attempted ignition when the condensate is blocked.

A fan post purge occurs when the fan continues to run after the boiler has been in operation. This is done to help cool the unit down and it is a normal function within the appliance.

This means there is an issue with the flow and return pipes are reversed. Although this is usually not the case on a combi boiler, If this occurs please check all isolation valves underneath the boiler are in the open position, all radiator valves are turned on full and the bypass is free flowing to see if this rectifies the issue, If it does it may be worth calling the installer of the boiler to take a look.

Our Logic and Logic+ boilers are very similar in appearance; the major components are the same but the software and displays on the boilers are different. Our Logic boilers currently have a 2-year warranty whereas Logic+ boilers currently have 7 years. 

A blank display is an indication that there is no power to the boiler. Alternatively a component within the boiler may have failed and a callout is required, please contact our Customer Service department on 01482 498660.

When your boiler displays a ‘C’ on the boiler screen and the burner light is also flashing, this means your boiler has reached the programmed temperature.

If your house has not met the set temperature and your boiler is showing this it could be caused by a circulation problem in the system. For more information regarding this you can contact our Customer Service team on 01482 498660.

A condensing boiler is a high efficiency boiler which runs at a lower temperature than older, traditional style boilers. It recovers energy through, what is termed, 'Latent Heat'. When the burned fuel products cool they turn in to a liquid and create condensation. 

Often, with a newly filled system, there can be air in the water used. Over time this is released into the system causing a pressure drop. Another cause of pressure loss could be not having enough expansion in the system.  There could also be a slight leak within the system which may not be noticeable without detailed checking.  Finally, it could be due to a component failure within the boiler. If the system requires topping up frequently it needs to be checked by a professional to find the source of the pressure loss.

When ‘0’ is displayed on the boiler screen it means the boiler is on standby. This means the boiler is not receiving a demand from either the hot water or central heating. Still need further guidance with your Ideal boiler? Why
