How did I guess t'was a Valliant.
Both those fault codes relate to the electronic circuitry. I can only give advice as you have to be a registered engineer for this one.
Let me get my facts straight the guy came to fix the loo cistern and managed to get water through the ceiling into the boiler cupboard, there after the boiler failed.
If that's correct like someone has already said get his insurance details for it is certainly his fault...........Water has entered the boiler and short circuited something. Most likely the NTC thermistor which sits high up in the boiler.
This particular fault caused by water ingress is a bu77er to diagnose properly, it could just be the sensor but the wiring and circuit board could also be affected. First thing I would do before starting any electrical checks would be to get my ladies hair dryer from the van and make sure everything was dry, it takes a good few minutes but is worth the effort and might even cure the problem if nothing has burnt out.
Then its a case of checking the resistance of the thermistor and working your way from there.
This could get expensive so get the first blokes details pronto.
Before anyone asks NTC is short for Negative Temperature Coefficient Thermistor.
