Hi,
I have just replaced the heat exchanger in a Vaillant VCW GB 242 E. It is from the old plastic unit to a smaller metal one with new pipes.
I have not powered it back up yet as the instructions recommend changing a part in the diverter valve and cutting a wire on the PCB.
Can anyone let me know if this is really necessary?
Thanks in anticipation
Adrian
