Ok got intermittent fault and I know these are a pig of a boiler to work on
Hot water fluctuates between hot and cold sometimes.
The boiler continually runs when calling for water but i have noticed the htw pipe gets warm but the ch pipe gets hot even when the heating is off
Checked sensor and isn’t that
And what’s the black square turn knob by the red and yellow wire on the diverter valve (not the micro switch that works ok)
Any thoughts appreciated
