It would seem after not using my heating over the summer that my baxi duo tec boiler is showing the error code e133 , I've tried everything that I can think of but the ignition flame light just isn't coming on, I've just put £35 on the gas meter so between the gas meter and the ignition flame coming on there is a fault.. suggestions anyone?

We had this problem. Running the hot water tap whilst pressing the reset button the boiler ignited and has remained working.

Had the same code on baxi duo tec .Spark electrode gap had closed up causing a "weak" spark.Early signs causing the burner to fire up with a "pop".Opened the gap up with pliers to get heating back on .Now running fine

Btw!... keep going with hot water from the kettle.
It's just takin' me a good 2 hours plus & about 15-20 kettle's full & a hot water bottle wrapped around the plastic pipe & now the Burner Light is back on.
Boiler on & working...back in business.
Ah!... the heat, joy.

whilst cold weather can effect external condensate pipes, the original electodes distort with the heat and cause the same E133 fault, there is now a modified set of ignition electrodes which have been developed to conteract this problem. Baxi will change them free if the boiler is still under warrenty. This can be a common fault on all Baxi Potterton Band A combi boilers

I have exactly the same fault. I have just telephoned British Gas who my contract is with and they said I would need to wait four days for a priority repair..

One kettle full of boiling water later and the boiler has fired up and the house is toasty warm. Thank you very very much all for fixing my boiler

I had an E133 error on my Baxi today. It turned out that the condensate pipe had frozen in the cold weather. I poured a kettle full of boiling water over the external horizontal pipe and after a minute or so a load of water came out of the pipe. After resetting the boiler everything was ok.

i take it it's a promax combi? if so your condensate pipe is most likely frozen, the white one coming out of the bottom left of the boiler, this causes ignition lockout. best to get it seen to quickly as they are known for flooding the gas valve and also damaging the fan, very pricey. if it's been happening since before the cold weather then the combustion ratio's probaly need adjusted, again a job for an engineer.

could be your condensate drain pipe going outside is frozen.Try boling water on it.It fixed mine
