Hello
Boiler F30e Themaclassic, boiler is not diverting all hot water into hot water pipe, rather its partly going into primary flow pipe, also when c/heating is on hot water is partly coming down hot water pipe
Please note the following points:
boiler makes crackling sound when central heating is switched on, sound is coming from Domestic Heat exhanger
Boiler & C/heating system had sludge in there.
The following has already been done;
changed diverter valve on pump side and valve side (which was knackered)
changed three way valve head motor -(which was knackered with water)
cleaned out sludge from system by flushing continuously at drain offs, and cleaned c/heating filter, strainer and Domestic Heat Exchanger (DHE) , DHE was cleaned with a soak in spirit of salts (32% hydrochloric acid) overnight
tested three way valve head to see if voltage from PCB is providing voltage to motor, it is at 17 V / 234V alternating as you switch on heating / hot water
Any advice really appreciated.
