Product Information

Low boiler pressure is a common problem with all boilers and Potterton boilers are as susceptible to this as any others.

I have the above controller. It cannot have the heating and water set to come on at different times so I want to change it out.

These include E131, E133, E151, E152, E160 and E161. How to Fix it: An issue with the central heating pump – the pump is struggling to push water around the system. This could be caused by a problem with the settings or even a blown seal.

This is another job for a qualified engineer as it involves testing components underneath your boiler’s casing. This is a problem that you will need an engineer to help you fix. If the problem is being caused by limescale, the engineer will be able to clean things up using specialist chemicals. He will probably do this by carrying out a hot flush. It is usually recommended to fix an issue with low pressure in a boiler by topping up the system pressure. This is quite simple to do using the internal filling loop. But if the problem is being caused by a leak, it is only a matter of time before it reoccurs. But if the water in the return pipe continues to be cold, this suggests that there is a problem with the water circulating in your system.

If your boiler is fairly old, our of warranty, and has a fault with a major component such as the PCB, it is usually wiser to replace the whole boiler rather than fix one component and then wait for the next one to fail.

On your Potterton boiler, this is most likely to be indicated by error code E125 or E193 showing up on your display.My goods were not delivered the day confirmed and only delivered the next day after chasing.The staff at My Tub were very polite and curtious. Both of these problems usually come down to an issue with the diverter valve. The diverter valve is the component in your combi boiler which directs hot water to either the taps and showers or towards your radiators. If the NTC thermistor itself is damaged, the engineer should be able to replace it. This component is not terribly expensive. If you have an older boiler, you might, therefore, want to consider replacing the whole boiler with an energy-efficient new boiler that could end up saving you money in the long run. # 3 – Cold Return Pipe One issue which is a bit more unique to Potterton boilers is the boiler beginning to heat up the radiators but then cutting off before they have got up to full temperature.
