IF THE RO 400 STOPS WORKING

Trouble-shooting table

To protect both the user and the appliance itself from incorrect use, the RO 400 has built-in warning

(alarm) devices which cause it to stop working under certain conditions. The table below lists these

warnings and their probable causes. The indicator lights have three statuses:

It is time to change filters or clean the

grid.

The inlet water pressure is too low.

Warning that filter or is blocked.

Warning of blockage in grid (i.e.

intake connection filter).

Warning of leakage/condensation

inside the base under the filter

containers.

The intake water pressure is too low,

i.e. less than 22 psi (150 kPa).

Warning that filter needs replacing.

Warning of reduced water quality.

Warning that the spigot has been on

for more than 20 minutes without a

pause, and that the appliance has shut

down automatically as a result.

Warning that calibration has been

started, but not completed correctly

(probably because the spigot has been

turned off before the full 10 minutes).

Warning of error in water quality

meter.

POSSIBLE CAUSE

• There is still time left before the RO 400 stops

working. Prepare for replacement of filter

and cleaning the grid.

• Check the inlet water pressure. Increase the

pressure to 22 - 145 psi (150 - 1000 kPa).

• Check that there is nothing inside the filter

containers which could be blocking the flow.

• If necessary replace filter or .

• Check the grid. See the section "To clean the grid"

• Check that all connections are watertight.

• If there is water inside the base, wipe it dry

(tilt appliance forward if necessary).

• A booster pump to increase the pressure to the

RO 400 can solve this problem.

• Check all the factors which can affect water

pressure (water supply, plumbing, grid, extra/

special filters).

• Replace filter . See "Replacing the filters".

• If the appliance is new and has never been

calibrated: calibrate the appliance.

• Restart the water purifier (by disconnecting then

reconnecting the electricity) so that the appliance

switches to flushing mode. Repeat this procedure

two or more times.

• Turn off the spigot and leave the RO 400

undisturbed for at least 30 minutes.

• Restart the appliance by disconnecting and

then reconnecting the electricity.

After automatic flushing the RO 400 will be

ready for use again.

• Restart the appliance by disconnecting and then

reconnecting the electricity to start flushing mode.

Recalibrate the RO 400.

• Restart the appliance by disconnecting and then

reconnecting the electricity to start flushing mode.

Wait for two hours. Turn on the spigot, wait for 2

minutes.
