•Sensor unplugged from board
•Sensor cable damaged
•Sensor not functioning
•Sensor unplugged from board
•Sensor cable damaged
•Voltage too high on electrical network
•Damage during transportation
•No water in the tank
•Water is too hot (>75°C)
•Water sensor removed from tank
•Defective water sensor
•No water fl ow
•Circulator pump blocked
functioning
•Circulator not properly purged
•Defective water sensor
•Water sensor removed from tank
•No water circulating (fi lter clogged,
underfl oor circulting valve is closed)
•Incorrect connection to the underfl oor
heating return fl ow inlet (inlet/outlet
reversed)
•Circuit not properly purged
•Circulator pump not functioning
•Sub-draft too high
•Set temperature too high
•Failure of the resistance
•Electrical back-up not allowed
• The air and defrosting sensors are
inverted on the electronics board
•The defrosting and water sensors
are inverted on the electronics
from the board
•The defrosting sensor is
connected to the air input, the
air sensor is connected to the
water input, the water sensor is
connected to the defrosting input
• The defrosting sensor is not
properly connected and she is measuring
air
• There is a leak in the refrigerant
circuit
• The expansion valve bulbs damaged or
broken due to work being carried out on
the appliance, or it being in contact
with a part that vibrates
• Defect in compressor
• The defrosting and water sensors
are inverted on the electronics
board
