IF THE RO 400 STOPS WORKING
SYMPTOMS POSSIBLE CAUSE ACTION TO TAKE
The membrane may be clogged
The hose for purified water is not
pressed all the way home at the
connection on the appliance. Or there
may be a leak at the connection of hose
to tap, or the hose for this tap may
have been shortened (cut) incorrectly.
The tap is leaking, which causes the
RO 400 to respond constantly to the
loss of pressure. The adjusting screw
in the tap may need adjustment, or
washers in the tap may be damaged.
If the temperature is higher than
30 °C, the flow rate will increase to a
level higher than the tap can handle.
The adjusting screw on the tap needs
adjusting.
Odour problems in the water from
the appliance may be caused by the
water purifier being left without
being used and with the electricity
disconnected, and on account of
microbial flora in the water.
• Descale the appliance. See "
Descaling".
• Check all connections.
• Check that both ends of the hose for purified
water are cut straight and clean, and not
deformed. Should be round, not oval in shape.
• Adjust the adjusting screw on the tap see "To
adjust the tap".
• Adjust the adjusting screw on the tap see "To
adjust the tap".
• Work through all the steps of the full "Flushing
procedure".
• Follow the "Disinfection" procedure.
Low water flow
The appliance starts
working on its own
(briefly, without tap
being turned on).
The flow of water
from the appliance is
uneven or jerky.
Odour
If the appliance has shut down automatically, it will have to be restarted by disconnecting then
reconnecting the electricity.
If a problem persists even after you have tried to trace it and correct it using the trouble-shooting table,
contact your dealer.
