IF THE WATER PURIFIER 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. Alternatively there may be a
leak at the connection of hose to tap, or
the hose for this tap may have been short-
ened (cut) incorrectly.
The tap is leaking, which causes the water
purifier 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.
When the purifier is not in use (with the
electricity disconnected) and there is bio-
logical growth in the water, or unpleasant
odour can occur.
• 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.
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 reconnect-
ing the electricity.
If a problem persists even after you have tried to trace it and correct it using the trouble-shooting table, con-
tact your dealer.
