if the hole is obstructed, clean it and, if necessary, install
upriver the safety valve a proper softener to reduce water hardness or a filter to avoid
dirt and dust coming from the network;
- damaged drainage pipe if the pipe is broken, replace it;
- high water network pressure if the water network pressure is high, install a
pressure reducer up river the safety valve or a tailored expansion vessel between the
safety valve and the appliance inlet pipe;
- high water temperature set-point if the hot water temperature set-point is high,
reduce it up to end user comfort is anyway satisfying or install a tailored expansion
vessel between the safety valve and the appliance inlet pipe.
From the by-pass pipe between the two tanks due to:
- wrong pipe tightening if the pipe is bad connected and water comes out from it,
restore the connection;
- faulty component if the by-pass pipe is damaged, replace it.
From the heating element fastons due to:
- corrosion if the heating element is damaged and water can enter, replace it.
From the tank due to:
- corrosion if the tank is damaged and water spills out, replace the product.
Insufficient

Power missing to the appliance due to:
- no power from mains (could be check by the end user, too) if the home power
network is not well-working, contact the power mains technical service;
- power missing to the PCB (could be check by the end user, too) if the appliance is
switched off, switch on it pressing the ON/OFF button;
- bad placed or damaged wirings if the power cable is disconnected/damaged,
connect/replace it.
Incorrect appliance working mode settings:
- low water temperature set-point (could be check by the end user, too) if the set-
point is not able to satisfy the end user comfort request, adjust the set-point;
- occasional huge hot water amount (could be check by the end user, too) if the end
user tapping profile is not predictable, deactivate the ECO function;
- incorrect time band in PREMIUM versions (could be check by the end user, too) if
the programming mode is set and the time band is not in compliance with the end
user comfort request, adjust the time band.
Incorrect thermostatic mixing valve setting (if present) due to:
- low water temperature set-point if the thermostatic mixing valve set-point is not in
compliance with the end user comfort request, adjust the set-point;
- faulty component if the thermostatic mixing valve is damaged or out of tune,
replace it.
Inlet plastic pipe broken due to:
- faulty component if the component is damaged, replace it.
Insufficient
water flow
could be check by the end user, too
network pressure is less than 2 bar, check if the home mains tap is fully open, if any
leakage is present upriver the water heater or contact the network technical service.
Inlet plastic pipe malfunctioning due to:
- component break if the component is damaged, replace it;
Pipes (inlet pipe or outlet pipe or by-pass between the two tanks) or safety valve
clogged due to:
- limestone if limestone is present, clean it and, if necessary, install a proper
softener upriver the safety valve to reduce water hardness;
- dirt and dust if dirt or dust is present, clean it and, if necessary, install a filter
upriver the safety valve.
Filter obstructed (if present, anywhere in the circuit) due to:
- limestone if limestone is present, clean the filter and, if necessary, install a proper
