MA-EN-OSMOSIS XENA10.1-RO-0220-22-FLC-21-V01.0
ID
SYMPTOM
PROBABLE CAUSE
SOLUTION
1
Zero/low
production
No water supply.
Wait until the water supply has
been restored.
Brass ball valve at entrance
fully/partially closed.
Open the entrance valve fully.
Insufficient supply pressure.
Check mains pressure. If it is lower than
2.5 bars, then you must install a pump
and its respective switches.
Flow restrictor obstructed.
Replace flow restrictor.
Drain obstructed.
Check if the drain line is blocked. If so,
unblock it.
Excessive waste.
Check the flow in the flow restrictor,
if excessive, replace it.
Cartridges obstructed.
Replace cartridges.
Membrane saturated.
Replace membrane.
No power supply.
Check the property’s power supply or socket.
Check voltage at transformers output.
If there isn’t any, replace it.
Pump in poor condition.
Check that the pump increase pressure at the
membrane housing inlet. If it doesn’t, change it.
Antileak system activated
Check if the antileak system has activated
itself. If so, detect the leak, fix it, replace
the absorbent material and lower the arm.
2
Excessive
production
and/or
elevated TDS
The membrane hasn’t been fitted.
Fit membrane.
Damaged membrane O-rings.
Replace the O-rings on the membrane.
Damaged membrane housing.
Replace the membrane housing.
Membrane damaged.
Replace the membrane.
Badly connected tubes.
Wire the connection between the wastage
and the permeate properly.
Damaged shut off valve.
Replace shut off valve.
3
Bitter or
acidic taste
Water with very low salinity level.
Fit a mineralizing postfilter.
7.- FAULTS, PROBABLE CAUSES AND POSSIBLE SOLUTIONS
ID
SYMPTOM
PROBABLE CAUSE
SOLUTION
4
Plastic or
synthetic taste
Worn postfilter.
Replace postfilter.
5
Unpleasant
taste and smell
Contamination.
Change the filters, membrane, postfilter
and sanitise.
6
White particles
in the water
Air in the system.
Wait for the air to pass as there’s no urgent
problem.
Excessive inlet
pressure.
Check the mains water pressure, if it is greater
than 4 bars it will be necessary to fit a pressure
regulator at the inlet to the osmosis system.
7
The osmosis
system doesn’t
stop throwing
water away
Shut off valve
deteriorated.
Replace shut off valve.
Non-return
valve deteriorated.
Replace non-return valve.
Excessive inlet
pressure.
Check the mains water pressure, if it is greater
than 4 bars it will be necessary to fit a pressure
regulator at the inlet to the osmosis system.
8
The osmosis
system starts up
sporadically
without water
consumption
Non-return
valve deteriorated.
Replace the non-return valve.
Excessive
inlet pressure.
Check the mains water pressure, if it is greater
than 4 bars it will be necessary to fit a pressure
regulator at the inlet to the osmosis system.
Leak in some point
of the system
and/or faucet.
Repair the leak and/or replace faucet.
9
The osmosis
system stops and
starts.
Very little inlet pressure,
less than 1 bar.
Bypass the minimum pressure switch (Danger
that the pump could work without water and break.
Minimum pressure
switch in bad condition.
Replace the minimum pressure switch.
Deteriorated non-return
valve.
Replace the non-return valve.
