Alpha InTec 34C E37 Error

[Thorn2211]

Evening,

Looking for a bit of advice.

I have an Alpha InTec 34C boiler installed.

Since putting the heating back on the boiler is throwing up an e37 error, this seems to be happening when the heating is on and then a tap is turned on for hot water. When the tap is turned off the error disappears most of the time.

However a couple of times the error has stayed on and I have had to turn off/on the boiler to reset.

E37 is a electricity supply low voltage.

Thought i would ask before calling anyone.

Could be a loose connection somewhere. Is your home powered in the normal way? Nothing ran off solar panels?

very well known fault it is the PCB transformer has been overheating, do you have a slight colour staining on a part of the front of the facia, slightly yellowish, good chance your boiler will still be under the Manufacturers warranty

Thankyou for the replies,

I can't see any obvious discolouring. Not under warranty so sounds like I will have to get an engineer to have a look. Sounds expensive.

Ianmcd is perfectly correct. Thankyou.
His post was spot on.
The PCB transformer (which is actually on the PCB) was faulty.
Yellowing to front also present.
Replaced PCB which included transformer. Cost of PCB £200 plus vat.
Now works perfectly although I would never buy an Alpha again.

@ianmcd is very good at advice and boiler faults

I'd rather have a boiler that doesn't need such comprehensive after sales service personally

Sorry please delete this post

I have a Alpha entec 28x with an E37 fault code, but is intermittent, would this mean that it could be something other than a transformer PCB replacement ? Also can an electrician or other competent person replace this ? Or would it need a gas safe person ?

thanks

You'd be better off starting your own thread rather than hijacking someone else's, which is against site rules. You'd need a Gas Safe Registered engineer to diagnose and replace
