Faults/Boiler

Why does my Combi boiler not work as well when I use multiple hot water taps?
A:

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. 

How do I check if my condensate pipe is blocked?
A:

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.

What is 'fan post purge'?
A:

This means that the fan continues to run after the boiler has been in operation to help cool the unit down, this is a normal function within the appliance.

How do I know which boiler is best suited for my home?
A:

There is a product selector tool available on our website which gives you a guide on what boiler would be best suit for your home. It asks for brief information on your home and then generates suggestions based on your input.

What does fault code FA flashing on a Logic Combi 35 mean?
A:

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.

What is the difference between a standard Logic and a Logic+?
A:

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. 

Which boiler is the equivalent to the one I have?
A:

There is a tool available on our website which gives you a guide on what boiler would be best suit for your home. It asks for brief information on your home and then generates suggestions based on your input.

How do I get a new installation/user manual?
A:

These are available to download in the form of a PDF file from our website free of charge. These can be found here.

My boiler display is blank, what does this mean?
A:

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.

My boiler shows 'C' and the burner light is flashing what does this mean?
A:

This means the boiler has reached the programmed temperature. If the house has not met the set temperature and the 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 services team on 01482 498660.

What is a condensing boiler?
A:

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. 

What are differences between a Combi, System and Heat boiler?
A:

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. A Combi boiler provides both heating and hot water instantly. A system boiler is designed to work with a cylinder to provide hot water as it does not have the hot water heat exchanger. It contains an expansion vessel and pump allowing the boiler to be installed in a sealed system. The Heat only boiler is the simplest type of boiler. It can be used on either an open vented system, which has a tank in the loft, or in a sealed system with the addition of an external pump and expansion vessel. Hot water is provided by using a cylinder.

What is 'Pluming'?
A:

Pluming is the effect seen from the flue on modern condensing boilers, it appears as a white "steam like" discharge from the flue. It’s a result of modern high efficiency boilers running at a cooler temperature than older, less efficient boilers did. It is safe however, there are a range of flue additions to remove the plume from the area. For further advice on this please either speak to your installer or call our Customer Services department on 01482 498660.

Why does my boiler lose pressure?
A:

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.

Where do I find my serial number?
A:

The serial number is displayed on a barcoded sticker located at the top of the boiler. Alternatively, it should be present on the Benchmark certificate completed by the installer when the boiler was fitted. If you require further assistance please contact our Customer Services department on 01482 498660.

What does pre heat mean?
A:

‘Pre-heat’ is a function that is designed to provide you with instant hot water when required. It works by infrequently heating the plate heat exchanger so that when hot water is requested it is already heated. This feature is not compulsory however, if not selected can take a few minutes before the hot water is at the appropriate temperature.

What does it mean when the '0' is displayed on the boiler screen?
A:

'0' Informs you that the boiler is in standby and not receiving a demand from either the hot water, or central heating.

What does it mean when 'D' is displayed on the boiler screen?
A:

'D' Informs you that the boilers fired up for a hot water demand.

What does it mean when the 'C' is displayed on the boiler screen?
A:

'C' means the boiler has a central heating demand.

How do I reset to remove my service message?
A:

On the older range of boilers this can be completed by holding the mode dial in the reset position for 3 seconds. For the new Logic+ and Vogue boilers this can be done by either pushing the reset button underneath the display, or going into the menu settings on the display.

Why can't I get hot water ?
A:

On a combi boiler you should check that the hot water temperature is turned up on the front, check the isolation valve underneath the boiler on the cold mains pipe is vertical/open. After this it is likely there is a problem within the appliance. On either a heat only boiler or a system boiler if the central heating work and the hot water doesn't this will be a system problem, possibly a zone valve not operating.
