Symptoms
Possible cause
Action to take
Low water flow
Clogged membrane
•
Descale the membrane. See « Descaling ».
The water purifier
starts working on its
own (briefly, with
closed tap)
Leakage (even very little) between
RO400C and the hoses.
•
Check all connections.
The flow of water
from the appliance
is uneven or jerky.
If the temperature is higher than
30°C, the rate of flow will increase to
much.
•
Check the water temperature, that should be
lower than 25 °C.
Absence of bubbles
in glasses with fizzy
drinks
The absence of mineral deposits on
the glasses prevents the bubbles. A
little score in the bottom of the
glass is enough to have again the
bubbles.
•
Use of pre-scored glasses
•
Use of a diamond-point pencil, code SPDCTA,
to score the glasses.
Bad drying
Rinsing with demineralized water (so
with almost complete absence of
surface-active product) produces a
less good drying result than with a
non-treated water.
•
Think about a place and a time for baskets
storage
•
The place for storage of glass baskets
should be well ventilated, so to have a good
drying for evaporation
Spots on glasses
Not correct dosing of detergents
and/or rinse aid additives.
Purified water needs less products
for the same action.
•
Manual dosing is not compatible.
•
Only a proportional dosing with products
suited for purified water is effective.
•
Tests for dosing should be carried out
whatsoever is possible with the supplier of
detergents and rinse aid additives.
If the water purifier has shut down automatically, it will have to be restarted by disconnecting and then reconnecting
the electricity.
