    Baxi Duotec Combi 24HE Error Code E133

    Baxi Duotec Combi 24HE Error Code E133 3rd Mar 17 at 7:44 AM
    Hi,

    We moved into a new house 6 months ago and it had the above boiler. A couple of months ago we got the error code E133. We reset the boiler and it started working fine and we've not have the issue since. Until yesterday and today. Yesterday we woke up with the error message. Yesterday I reset the boiler, and it worked fine for the rest of the day. Today I woke up and the same error, I reset it and it worked fine again. I don't suppose anyone has an idea of what this might be?

    I was going to call a gas engineer out, but my worry is that they won't be able to see why the error is happening because it's all working fine when they come. Or should they be able to see what the problem is despite it working when they come? Or will this just end up being a try and see thing?

    Thank you

    Glen

    Sounds like a good plan. I called NPower, and they are being really slow about it. They needed to call someone, who then needed to call someone else. They are going to ring me back at some point today or Monday to book it in!! I'll keep you updated on what's happening! We've not had the error for the last couple of days. Might be because it's been a lot warmer!

    Ah ok. That'll be why they were so rubbish with it then. I'm based in Enfield, so will have to do a google search and see who it is. Thank you for your help on this.

    It's not the sensor lead. Changed that and same problem!

    It's not given us the error message for a while now. Never lights up first time... Closer to 3rd time it lights up with a big bang! I changed the ignition lead and there wasn't much change. Am trying to work out of there is much point getting it diagnosed until it dies again. I think i read since people are able to work out what is wrong just by listening to the light up sequence and noting where it goes wrong. That is very very impressive.

    I think you had the electrodes changed, if you have and it's coming on with a bang then you need someone to test the gas inlet pressure, the co readings and the low gas rate as the boiler will light on low rate.

    That's helpful. I did have the electrodes changed. I would have thought the engineer who changed it would have checked the gas inlet pressure. But unlikely considering he couldn't work out what was wrong with it!

    I changed both the electrode leads, and the earth cable to the ignition. I've not had the error code for about a week now. But the boiler still doesn't sound healthy. It's taking about 3 attempts to light up each time. It's also fairly noisy! It is the Gas valve that sorts out the inlet pressure?

    The inlet pressure is the gas pressure coming from the meter to the boiler. The low gas rate, what the boiler lights on is controlled by the gas vavle. Either way you need a gas safe engineer to look at this as it needs to be check with a emissions tester. It doesn't take to much to make it burner badly and give off poor readings which can lead to co issue.

    Thank you for this. I've not actually done anything to it, and the error message has disappeared for the last week or so. It's firing up on the 3rd or 4th go, so I suspect the error will come back again at some point in the future. When it does I'll get the gas valve replaced. It's weird how it works fine for large chunks, then has a week or so of causing problems!

    The gas valve may not need replacing, you may just need a decent gas safe engineer to set the gas valve up correctly. It has adjustment points on it and the manufacturers instructions will tell them the readings they need.
