If, with tension available, all displays remain off, it means that the electrical supply does not reach the
main board, or this latter is damaged.
Possible causes:
A) Over-tension and/or supply fuse failure. Open the fuse housing next to the supply plug, take out the
spare fuse and replace the damaged one.
B) Damage to the actuators board or the main board. Contact the service
To assure a long working life of the internal parts of the device, are necessary following periodic checks:
1. Clean the filters (3) regularly, particularly if the water contains a high quantity of lime-scale.
2. When switching off the doser-mixer, set always the temperature regulation knob (5) to its mid
position, to allow a minimum number of moves in the mixer valve, particularly when deliveries at the
same temperature are carried out.
3. To clean the external surface of the doser-mixer, use a soft sponge and water or a neutral detergent;
for more resistant grime, use alcohol or turpentine.
