Hi all

As title boiler displaying error code 133. As per service manual checked for voltage on PCB X2 connector across pins 2 and 5 and no power. Changed PCB to no effect, same error and still no power at X2 across 2 and 5. Have checked Ignition electrode and is at manual stated gap tolerance. No problems with gas supply. Any ideas I can check while I wait til monday for another engineer??

Thanks in advance.

You have already exceeded what you should have been doing as non gas registered. Probably spent more than a fixed price repair too.

You need a competent boiler engineer.

Did you have your multimeter set for DC volts and connected it as per instructions in Baxi manual?

I'm a computer engineer Tony so I know my way round a multimeter and PCB. As for the rest I haven't touched the gas or plumbing and if you don't try you don't learn. For better or worse I'm not one of those people who takes well to being told I can't do something.

I have no problem with you doing any electronic or water tests or work.

But you have removed the ignition electrodes and that is classed as work on the gas/safety aspects of the boiler.

"Gas Work" is defined as any work which is related to gas or combustion or safety devices. It includes removing the combustion chamber cover and touching the ignition electrodes, gas valve, fan etc.

It can also include changing a PCB when there are gas settings on the PCB. Its very common to have ignition settings on the PCB and some have min and max gas presures as well as gas type in some cases.
