Baxi Duo-tec HE boiler fault. E133

[RMS]

Hi all,

My boiler is showing this fault.

I have measured voltage across terminals 2 and 5 on the PCB - X2 connector and am getting around 180V DC for about 2-3 seconds when the igniter clicks then the boiler fails to ignite and the voltage is removed.

A friend who is a plumber checked the gas to the boiler which was present but he does not repair boilers .

My gas meter has been making a whining noise recently. I wondered if the meter is at fault or the regulator. The boiler is the only gas appliance.

The reason I ask this is because I am considering getting British Gas out with a one off charge or just a local heating engineer. If its something small then I would rather get a local heating engineer.

What do you guys think?

Probably just needs a good and proper service.

I've had many of these fault with this and a service has fixed it.

As the likely cause is a part that is sealed to the combustion chamber you need an RGI.

Any more info and I risk getting slated by the CC police on here

Electrode gap to small.

 

[Baxmax]

Or to wide......................

 

[gasright]

Or missing.......……

 

[newbuildinstaller]

im sure e133 can be a blocked flue, or blocked condensate pipe or bad gas supply

 

[powell30]

Trust us......90+% electrode issue.......RGI required

 

[gas4you]

Or as I was implying, just covered in crap build up

I'm having the same problem yet the boiler is firing? Running for a minute or 2 then cutting out. That could be the electrode could it?
