Hi,
Any help much appreciated. Moved into house with vokera syntesi 29e. Ok for couple of months then water from hot taps started to be lukewarm then no heat at all. At same time rads upstairs getting very hot. Booked a local plumber who changed the plate (?) heat exchanger, I think that's what he said. Seemed fine for last few weeks but now similar problems except boiler now shuts down with code 07 and then reverts to 02. Temp on display jumps very quickly from 30s to 90s in few seconds before boiler shuts down. Any ideas - can't get hold of original plumber so just want a heads up before calling someone else.
Thanks!
