Hello, do not be tired, master, I encountered this problem, I increased the resistance of the thermistor, the problem of Ec was solved, now it gives error e7, what is the solution?
E7 comes in 2 cases 1. water level sensor problem when it provides abnormal frequency (at low level the signal must 30KHz and at full water level it must 15KHz) if the signal is stable for more than 5 seconds, then 2. it is pressure switch error (When the error occurs, water drain pump will operate for 3 min. and then turn off the water drain pump. Then the display shows ‘E7’ indicating a pressure s/w error indicator
