B4. TIME OUT RINSE:
Cause:
The set rinse time has been exceeded.
Check:
1. Checkthefreerotationoftherinsepump.Shouldtheimpellerbeblocked,rotatethe
motor shaft manually, by a screw-driver (see pict. 4).
2. Rinse pump damaged. Replace if needed.
3. Circuit board failure. Change the circuit board.
B5. BOILER OVERHEATING:
Cause:
The water temperature in the boiler exceeded 105°C.
Checks:
1. The boiler pressure switch failed. Replace if needed.
Before replacing the pressure switch, drain the boiler completely.
2. The pressure switch hose is clogged. Blow air to unclog it.
3. Check the sensor integrity. Replace if needed.
4. Check the boiler coil-switch protection
5. Circuit board failure. Change the circuit board.
E1. WATER LOAD FAILED:
Cause:
Themachinewash-tankwasnotlledinthemaximumforeseen15min.timelimit.
Checks:
1. No water supply to the machine. Open all water supply valves.
2. Check the right functioning of the solenoid valve.

the tank pressure switch.
6. Circuit board failure. Change the circuit board.
E2. TANK PROBE FAILED:
Cause:
The circuit board does not detect the wash-tank sensor.
Checks:
1. Check the electrical connection between circuit board and sensor.
2. Check if the sensor works properly.
3. Check that the sensor did not overheat.
