6.4 - Troubleshooting
• The heat pump is not working
Check that:
• The desired water temperature is higher than the temperature
of the water in the tank.
• The appliance is connected to a power supply.
• The green light is on.
• The appliance is not in holiday mode (symbol
).
• The air intake or ambient temperature is under -7°C or over
+35°C (ELEC MODE displayed).
• The timer has not been programmed to stop the appliance
operating ( «economy» light will be on).
•The appliance is not in load shedding mode.
• An error message is displayed on the screen (see § Error
message codes).
Do not adjust settings

• Condensates are not draining
(water present under the appliance)
Check that:
• The drainage system is not blocked:
- Remove the cover (see § «External control» procedure).
- Check the opening.
• The tubes do not have bends or ‘‘U’’ shapes that could collect
water.
• The end of the tube gives out onto open air.
•The tank is properly positioned (vertical position and no
tilting).
• Electrical back-up is not working
Check that:
• Your electricity provider or your timer is not preventing the
appliance from functioning ( «Economy» light on).
• A heat-limiting safety thermostat for electrical back-up has
not been activated after over-heating (>85°C). If this is the
case, reset it.
Before resetting, check:
- That the heating element does not have limescale.
- Clean or replace if necessary.

• No hot water
Check that:
• The volume of water consumed is not higher than the volume
in the tank.
