ah else I forgot to say that the plug was melted could it damage something of the card?
Probably not, unless there has been a short circuit inside the machine. Check what I told you in the answer below
there is water oresion but no the current does not reach the water inlet valves I guess why not feel sorry to vibrate
If they do not vibrate, the valve may not work, or may not receive voltage. If you do not have a tester to measure the voltage you can connect a common lamp to the two wires of the valve and check if it turns on. If you turn on you must change the valve because it does not work. If you do not turn on the problem either it is in the wiring or on the board
