insecticides, solvents or aggressive detergents: these can damage the unit’s painted and plastic parts.
IF THE WATER COMES OUT COLD
Models with the interface shown in Fig. 8a/b
Disconnect the appliance from the power supply and have the following checked:
- the presence of voltage on the power terminal block (Fig. 7, Rif. M);
- the circuit board;
- the heating elements;
- inspect the bypass pipe (Fig. 5, Rif. X);
- the sensor holder rods (Fig. 7, Rif. K)
Models with the interface shown in Fig. 8c
- Check that the appliance is connected to the power supply and that the external bipolar switch is ON;
- Check that the temperature adjustment knob is not set to the minimum;
- Check the heating elements;
- Inspect the bypass pipe (Fig. 5a, Ref. X);
IF THE WATER COMES OUT BOILING HOT (STEAM IN THE TAPS)
Models with the interface shown in Fig. 8a/b
Disconnect the appliance from the electricity supply and have the following checked:
- the circuit board
- the amount of scale on the boiler and components;
- the sensor holder rods (Fig. 7, Rif. K)
Models with the interface shown in Fig. 8c
Disconnect the appliance from the power supply and contact the Technical Assistance Service.
THE HOT WATER DELIVERY IS INSUFFICIENT
Disconnect the appliance from the electricity supply and have the following checked:
- the pressure of the water mains;
- the condition of the deflector on the cold water intake pipe;
- the condition of the hot water pipe;
- the electrical components
WATER TRICKLING FROM THE PRESSURE SAFETY DEVICE
During the healing phase, some water may trickle from the tap. This is normal. To prevent the water trickling, a
suitable expansion vessel must be installed on the flow system. If the trickling continues even after the healing
phase, have the following checked:
- device calibration;
- the pressure of the water mains.
Caution: Never obstruct the appliance outletl
IF THE PROBLEM PERSISTS, NEVER ATTEMPT TO REPAIR THE APPLIANCE YOURSELF, BUT ALWAYS
