Why is my boiler showing E119?
In most cases, a E119 fault on a Baxi Potterton boiler indicates that there is water leaking somewhere in the system, and this is a job usually best handled by the professionals; leaks can be tricky to track down, and may require specific specialist knowledge to repair and rectify.
How do I release pressure from my boiler?
How to reduce your boiler pressure
- Switch off your boiler and wait for the heating system to cool.
- Identify and check the boiler pressure gauge.
- If it’s above 2 bars, you’ll need to reduce the pressure.
- Ensure the filling loop or relief valve is tightly closed.
Why does my boiler keep losing pressure?
The most common reasons for a boiler to lose pressure are: Releasing air or water from a radiator when bleeding it. A leak from the appliance or on the system most commonly from radiator valves or system components.
What does E19 mean on a boiler?
Fault codes requiring an engineer or installer visit
| Code | Possible fault | User action |
|---|---|---|
| E19 | Auto refill on too long | Installer to check system for water leaks |
| E20 | Heating flow sensor fault | Engineer visit required |
| E28 | Flue sensor fault | Engineer visit required |
| E40 | Heating return sensor fault | Engineer visit required |
What will happen if my boiler pressure is too high?
If the boiler pressure is too high, there’s an increased chance of leaks developing in the system. But if boiler pressure is too low, the system won’t work as well. So keeping the correct boiler pressure is important to make sure that your system heats your home efficiently.
Can a boiler explode?
A boiler explosion is a catastrophic failure of a boiler. There are two types of boiler explosions. One type is a failure of the pressure parts of the steam and water sides. There can be many different causes, such as failure of the safety valve, corrosion of critical parts of the boiler, or low water level.
Will bleeding radiators help boiler pressure?
Yes. During the process of bleeding radiators, air is released from within them, which in turn reduces the pressure in your boiler system.
Why does my Baxi boiler keep losing pressure?
There could be debris inside the pressure relief valve. This is the safety valve that usually discharges water if the pressure in the system gets too high. If it is dripping with water and the pressure gauge is too low, your Gas Safe registered engineer will need to clean out or replace the safety valve.
