Hi! I too have a LG Therma V from 2016. It has been plagued all it's life with CH 14 error. During the warranty period the control panel was replaced and things lasted couple of years. Then the error got back each year after summer. Pressure drop I was told, so I fitted a self regulating valve to top the pressure in the circuit. Early this year the DHW stopped working, gives me the CH 14 but the UFH keeps going (set point at 30ºC) so I switched off DHW (using my tank internal heater) Until this weekend where the CH 14 became omnipresent. Even if I reset (power-off-power-on) the error is tripped in less then 30seconds... I've run out of clues on whats going on, the circuit is fully pressurised at 2.5bar.
