Trouble Shooting

If the following problems occur, please check as follows:

Problem

Solution

No operation of the
pump   to   generate
purified water

Check if the water supply pressure is high enough to work. The RO con-
troller box does not start the pump under low pressure.

Check if either high pressure switch or flush valve works.

Check if the fuse on transformer is burned; if so, then check if post in-line
carbon filter (T33) or PP cartridges is blocked, it may cause the pump to be
overloaded.

No operation at all

Check if power supply is normal.

Check if the water supply ball valve has been turned on (check if water
pressure is normal).

Check if the water storage tank is full of water.

No automatic opera-
tion

Check if there is any wrong operation.

Check if the high and low pressure valve is normal.

Pump head leakage

Check if post in-line carbon filter (T33) or PP cartridges are blocked, which
may cause the leaking. Sometimes the leakage may be caused by the in-
creased water pressure inside the pump head that cannot be released. If
so, replace all the carbon cartridges and send the pump for repair.

Either a weakened membrane or the blocked scale could cause the leak-
ing as well.

The water cannot flow out due to the blocked RO membrane, which is
caused by a blocked flow restrictor. This causes the pump head to be filled
with high pressure water that can cause a leak. Improve the relevant com-
ponents.

No   water   purifying
with   pump   normally
working

Maybe the RO membrane is blocked or the pump is out of pressure. If the
RO membrane is blocked, replace it. If the pump has no pressure, check if
it is due to either the pump having operated for too long or the filtering ma -
terials   being   blocked   and   the   adequate   maintenance   not   having   been
done, which may cause the pump structure to weaken. Send in the pump
for repairing.

Lack of purified wa-
ter   outlet   with   filled
tank

The cause may be a lack of air inside the tank. Please recharge the air
(7 psi) and check if tank has air leakage. If it does, please replace the tank.

If the post in-line carbon filter is blocked, replace the filter.

Continued dirt water
discharging with the
tap closed

Check if flush valve is operating normally; otherwise, replace it.

The input water valve was damaged.

No complete stop or
restart   of   RO   sys-
tem with filled tank

High-pressure switch is out of work. Please repair or replace it. 

Check if valve is releasing pressure and is not stuck. Please replace it.

Too   little   purified
water volume

Check if the filters are dirty or have served for too long. If the RO mem-
brane is dirty or has not regularly been flushed, replace it.

Check if the water is too cold.

Water   supply   pres-
sure quality beneath
that of the new sys-
tem

Please replace the pump.
