Troubleshooting Reverse Osmosis Pumped Display Codes

Below are the Codes you might see displayed on your pumped reverse osmosis system.

For product codes RO-DEN-PMP |RO-PMP | RO-HP-PMP

CODE DISPLAYED: F / Flush

1. The power indicator light comes on when the machine is turned on, and it
flushes automatically for 30 seconds.

2. After 4 hours of cumulative water production, if there is no flushing in
the middle, it will automatically flush for 18 seconds.

3. After exiting from the water shortage program, it will automatically flush
for 5 seconds.

4. The lower two digits of the small digital tube display the remaining
backwash time, and the clock symbol flashes once a second.

5. Press the strong flush button to force flush for 30 seconds;
(The pump starts up, the water inlet valve opens, and the
flushing valve opens).


CODE DISPLAYED: 8 / Work

1. When the high-pressure switch detects that the water pressure in the tank is lower than the set value, the pure water machine enters the water production process.

2. The lower two digits of the small digital tube display the current TDS value.
The upper limit of TDS is 100PPM. If it exceeds 100PPM, the symbols "100" and "OVR" will flash alternately.

3. The probes and computer board have already been paired correctly so do
not change their postion.

4. TDS measurement can be susceptible to interference, so please
install the probe into the pipeline for measurement, otherwise the accuracy can be
affected. 

5. Any air bubbles in the pipeline will affect the TDS read's accuracy.


CODE DISPLAYED: 8 / Full

1. When the high-pressure switch detects that the water pressure in the tank reaches the set value, the pure water machine enters the "water full" process.

(The pump stops, the water inlet valve closes, and the flushing valve closes)

2. The display shows the last measured TDS value at the time of water production or
flushing.

CODE DISPLAYED: 8 / Lack

1. When the low-pressure switch detects that the incoming "raw water" pressure is lower than the set value, the pure water machine enters the "water shortage" program and the buzzer / alarm / beep sounds.

(The pump stops, the water inlet valve closes, and the flushing valve closes)

2. The TDS value is not measured or displayed during this time.

CODE DISPLAYED: 6 / Check

1. If there is no water in the tank (shake it to check) after 12 consecutive hours of water production, it means the RO is malfunctioning and has entered the maintenance procedure. 

The buzzer / alarm / beeps sounds rapidly.

(The pump stops, the water inlet valve closes, and the flushing valve closes)

2. The TDS value is not measured or displayed during this time.
