TROUBLESHOOTING
The machine does not switch on
No power supply.
Check the electrical circuit.
The machine does not warm up
The thermostats have intervened The power supply does not reach the boiler.
Replace the thermostats (if of the One shot type) If they are manual, reset them If they are automatic, they are reset automatically Check the electrical connections.

Flow meter

1) upper body
2) flow meter
3) magnet
4) O-ring seal
5) lower body
A) Board
The water enters, hits against the blades of the flow meter, causing it to turn. The magnet passes beneath the board and transmits the number of revs to it, which in turn transmits it to the main board.
Anti-scale filter


Function:
# Reduced limescale deposits that take longer to form.
# Improved water quality.
# Better taste due to ideal water hardness
Descaling duration / efficiency:
# - 10 Degree dH
# 60 litres
# 2 months
To obtain a linear characteristic of its effectiveness, throughout the duration of the descaling process, the water is split according to the degree of hardness in a three-phase by-pass (A, B and C).
