SOLUTION
Wait until the water supply has
been restored.
Open the entrance valve fully.
Check mains pressure. If it is lower than
2.5 bars, then you must install a pump
and its respective switches.
Replace flow restrictor.
Check if the drain line is blocked. If so,
unblock it.
Check the flow in the flow restrictor,
if excessive, replace it.
Replace cartridges.
Replace membrane.
Check the property's power supply or socket.
Check voltage at transformers output.
If there isn't any, replace it.
Check that the pump increase pressure at the
membrane housing inlet. If it doesn't, change it.
Check if the antileak system has activated
itself. If so, detect the leak, fix it, replace
the absorbent material and lower the arm.
Replace the O-rings on the membrane.
Replace the membrane housing.
Replace the membrane.
Wire the connection between the wastage
and the permeate properly.
Replace shut off valve.
Fit a mineralizing postfilter.

SOLUTION
Replace postfilter.
Change the filters, membrane, postfilter
and sanitise.
Wait for the air to pass as there's no urgent
problem.
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.
Replace shut off valve.
Replace non-return valve.
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.
Replace the non-return valve.
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.
Repair the leak and/or replace faucet.
Bypass the minimum pressure switch (Danger
that the pump could work without water and break.
Replace the minimum pressure switch.
Replace the non-return valve.
