How do I fix an E10 error on my boiler?

Question

The display on my boiler shows E10 and it won’t fire up. What do I do?

Muhyideen · Accepted Answer

If it is an Alpha boiler, it will most likely be low pressure. If the pressure keeps dropping when heating is on then the boiler will require a diagnostics to be carried out by a gas safe engineer.

Soleman · Answer

When the water pressure is low in heating it shows this code increase the water pressure up to 1..5 max,

Rafiz · Answer

You need an engineer to diagnose the underlying fault on your boiler. This code usually means the boiler is over heating. Let me know if you would like me to attend.

Chris · Answer

E10 error generally means low water pressure in your boiler 
It could be something as easy as refilling the system to between 1 and 2 bar
Or if the problem persists you may need a engineer to resolve

Nirvair · Answer

An E10 error on a boiler indicates low system water pressure. To fix this, you need to repressurize the system by using the filling loop to add water, aiming for a pressure between (1) and (1.5) bar. If the problem persists after repressurizing, there may be a leak or a fault with the pump, and you should contact a qualified engineer

Tyrone · Answer

You need to top up the pressure of the boiler via the filling loop.

Ivo · Answer

Probably is low pressure in the system. You need to find where is your feeling lump and top up the water level up to 1.2 bar

water pressure or circulation problem 
1. Check your boiler pressure
	•	Look at the pressure gauge on the front of your boiler.
	•	It should normally read between 1.0 and 1.5 bar when the system is cold.
	•	If it’s below 1 bar, your boiler has low pressure, which often triggers the E10 error.

2. Repressurize the system
	•	Find the filling loop (a small silver braided hose under the boiler, with one or two black or blue handles).
	•	Turn the handles slowly to let water into the system until the pressure gauge reaches 1.2–1.5 bar.
	•	Then close both valves tightly.
	•	Reset the boiler (press the reset button or power it off/on).

Hi, if it’s an alpha boiler it needs the pressure topping up to between 1-1.5bar
