Question about LG Heating & Cooling
It appears to be an error 22. According to the LG bible, it means an overcurrent protection has activated. In most cases, unplug the machine or switch off from power supply for at least 15 minutes, it should reset the main control board. If this doesn't work , it may have damaged the board. Alternatively, if your machine is on 3 phase, check that all fuses / circuit breakers in your meter box are OK and switched on. You may have a weak or disconnected power supply.
