FAQs & Help

Please contact the installer

• The boiler has been reset too many times in 15 minutes.

• Turn the power to the boiler on and off again to reset

• Reset the boiler

• If this does not fix the problem, please contact us quoting error code L4 as this will require a visit from an engineer.

• Rotate all knobs fully clockwise

• Turn the boiler off

• Turn the boiler back on and then press restart

• Turn your thermostat to its maximum position and check if a C appears on the boiler display. If the boiler fires and the radiators come on, this means the room thermostat wasn't set higher than the room temperature.

• If the boiler still doesn't fire, please contact us as this will require a visit from an engineer

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.

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.

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. 

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.

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.

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. 

If your home has a heat only or system boiler, it’s important to know they cannot tell the difference between a demand for heating hot water and a demand for central heating like a combi boiler can. 

If you do have this problem with a system or heat only model you need to contact a plumber, not your boiler manufacturer. This is because a system or heat boiler only works off one demand and that is to heat up water — it’s the controls that do the rest.

On the PRT3, the reset button is located on the transceiver unit at the front of the boiler and on the programmable room thermostat. These should be held in for 5 seconds with the unit left next to the boiler for 15 minutes to pair. On the Touch programmer, this should happen automatically but can also take up to 15 minutes. If you require further assistance please contact our Customer Service department on 01482 498660.
