Hi Lusango I thank you for the prompt response ... if the pump perfectly throws water overflow system either since I do not lose water. I have already tested the motor apart the resistance, the pump. The solenoid valves check the flowmeter and I have reached the conclusion that it can be the control board since I tested the board only without any external connection and it does the same thing to me .. it would be the damaged micro-sensor at a glance the board does not present any short circuit since It seems strange to me that it is damaged by itself
