If an engineer is needed, or you’re in any doubt whatsoever always consult one. You can get free boiler repair quotes using Boiler Guide.
|Top 5 Potterton Boiler Problems||Potterton Error / Fault Code|

|Frozen condensate pipe||E133|
|Boiler keeps turning off||–|
When the radiators around your home aren’t heating up or are only partially heating up then it’s an indication that there’s too much air in the heating system, preventing the hot water from ciculating properly. To get your radiators heating up again, they need bleeding.
How to fix the radiators
By bleeding the radiators that aren’t heating up, you’re allowing the air to escape so that the hot water can circulate. Follow our guide to bleeding a radiator for step-by-step instructions on how to get your radiators working again.
A sudden drop in boiler pressure is a strong indication that there’s a leak somewhere in the system. If this is the case, you should turn off the water supply and contact a Gas Safe registered engineer right away. Having said this, boilers can gradually lose pressure over time and increasing it is something you can do yourself.
How to increase boiler pressure
As well as the E119 error code, you can see if your Potterton boiler has low pressure by looking at the pressure gauge – if you see the needle pointing to anything lower than 1 bar, the system is low on pressure. Ideally, it should be around the 1.5 mark. Increasing boiler pressure is something you can do yourself, we have a guide to increasing boiler pressure that will take you through the process a step at a time.
If there’s no hot water coming from your taps, then there could be many potential causes but it’s commonly a fault with the diverter valve. The diverter valve is responsible for directing hot water to either the radiators or taps and showers, depending which you want at the time. If it gets stuck then only one of these will be getting the hot water.
How to get the hot water flowing again
You’ll need to hire a Gas Safe registered engineer to to either repair the diverter valve or replace it, depending on its condition.
Condensate pipes are responsible for transporting acidic water, produced by waste gas, away from the boiler and outside down a drain. Due to being outside, it faces the risk of freezing in the colder months. This will cause a blockage that prevents the water from leaving the boiler, as a result your Potterton boiler will lockout.
How to thaw a frozen condensate pipe
Thawing a frozen condensate pipe can be done yourself without the need for a heating engineer, you can find a guide to thawing out the condensate pipe on Boiler Guide (including a video) but if you feel the slightest bit unsafe get in touch with a Gas Safe registered engineer.
If your boiler is experiencing low water pressure, thermostat issues, a lack of water flow due to a closed valve, then your boiler may keep switching off. If you can’t put your finger on the issue, it’s a good idea to call out a Gas Safe registered engineer.
Need a boiler repair?
To help you identify the potential causes of some common boiler problems, we’ve put together the table below so you’ll know if you’ll need an engineer.
|Problem||Possible Cause||Do you need an engineer?|
|No heat or hot water||Broken diaphragms and airlocks, failure of motorised valves, issues with the thermostat or low water levels||Yes|
|Leaking and dripping||Most common cause is a broken internal component but it will depend where the water is leaking from||Yes|
|Banging, whistling or gurgling noises||A common cause is air in the system, alternatively it could be that the water pressure is too low or it’s kettling||Yes|
|Pilot light goes out||Could be a broken thermocouple which is stopping the gas supply||Yes|
|Losing Pressure||Could be a water leak in the system, the pressure relief valve needs replacing or due to recently bleeding radiators||No, unless there’s a leak|
|Frozen condensate pipe||Your boiler should display a fault code or warning notification (consult your boiler manual)||Yes|
|Thermostat issues||Thermostat may be turned off or not set to the correct settings (time etc.)||Consider replacing the thermostat|
|Kettling||Limescale or sludge building up on your boiler’s heat exchanger||Yes|
|Radiators not getting hot||Sludge or air may have built up in the system or there’s an unequal distribution of heat||You will need to bleed the radiators which doesn’t require an engineer unless you don’t feel like carrying out the task yourself.|
|Boiler keeps switching itself off||Could be low water pressure, a problem with the thermostat or a lack of water flow due to a closed valve, air or the pump not circulating the water in the system properly||Yes|
If your Potterton boiler is displaying an E followed by a series of numbers then it’s letting you know that there’s a fault. If you’re seeing an error code then you need to know what it means so take a look through our list of Potterton error codes to find out.
