......Or freeze the pipe. And i wouldn't change existing stopcock, i would just cut a new one in above it if you have room....or unscrew the shaft of existing one and replace with a new one.
Not to freeze you will need static water and a good freezing kit!
The boiler is unrepairable......end of. The 'tank' was never available as a spare as the 'tank' is the boiler!
The seal you refer to is a combustion seal not a water seal.
Finally, as has been said this is not a boiler to mess with. Just replace it......you won't regret it.
If all heat lights are lit on dhw and you still get little hot water then your plate h/x is scaled/blocked or your diverter valve has gone. I bet the later as it doesn't kettle when all lights are lit
No the gauge reads pressure not water volume. So '0' means no pressure not system empty.
These units are sensitive to pressure and do drop out earlier on the gauge than some boilers so to get to zero must mean a leak. And a pretty quick one too
Yes!
Might be electrodes/door seals or pcb or something else depending on what 'lockout' code it is but heateam carry em all on the van......and the repair is guaranteed
E133 without frozen condense pipe indicates a gas related fault.....it will not be the fan.
The solution is almost certainly simple and the part/s won't be expensive but unfortunately involves gas related work.
Get someone in who knows what they are doing! or get a fixed price repair off...
The spark earths before passing through the ignition electrode and jumping across to the earthed electrode......hence multiple ignition attempts and some times explosive ignition due to gas build up.
Replace em or better yet change the door which include the new style electrodes designed to...
