CAUSE
- Check the efficiency of the contacts of J3 connector on the board;
- Check the state of the pressure switch verifying ohm-continuity on
J3 wiring connector, pins 2 and 4 (only with empty tank), pins 2 and
3 (only with water in the tank) and pin 2 and 1 (only with water in the
tank over half door glass level);
- Ambient with a high rate of humidity;
