Potterton E133 and water from flue

[sospan]

I was in the loft and noticed that the flue to my Potterton HE24 had come apart at a 90 degree joint. I pressed the plastic pipe back together (this has happened once before). AS I did this I heard a trickle of water flowing backwards towards the boiler.

The boiler started to flash E133. I noticed that the inside of the boiler was awash with water (condensate?). I know E133 is a gas flow problem, but any idea on what actually may be broken?

This is a condensing boiler, so the condensate/water will run back into the boiler, it may have been the heavy rainfall or a blocked condensate pipe that has caused the boiler to fill with water. Hopefully the E133 fault is just because the ignition and lead is lying in the water if allowed to dry out then it should work. Otherwise - it could be that water has also entered the gas valve, which will need replacing.

Thanks. It dried out after a few days (we went on holiday the next day)
