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 spigot,
or the hose for this spigot may have
been shortened (cut) incorrectly.
The spigot is leaking, which causes the
RO 400 to respond constantly to the
loss of pressure. The adjusting screw
in the spigot may need adjustment, or
washers in the spigot may be damaged.
If the temperature is higher than
86 °F (30 °C), the flow rate will
increase to a level higher than the
spigot can handle. The adjusting
screw on the spigot 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 spigot see
"To adjust the spigot".
• Adjust the adjusting screw on the spigot see
"To adjust the spigot".
• 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 spigot
being opened).
The flow of water
from the appliance is
uneven or jerky.
Odour.
If the appliance has shut down automatically, it has 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.
