Booster Pump Starting and Stopping Frequently Reminder
The front panel screen shows code E04, buzzer sounds 5 times.
There is an internal pressure imbalance. Disconnect the power. Turn on or turn off RO faucet
completely, remove all tubing crimps. Make sure the faucet is not blocked and power on
the system again.

Loud Sound of RO System
The sound will not exceed 65 DB, which makes no difference to everyday lives (65 DB is
tested under standard laboratory conditions, feed water pressure is between 14.5 PSI and 87
PSI). Loud sound may be caused by following reasons:
a. The system is not positioned in a flat area. Make sure the system is placed smoothly
without shaking.
b. The system is placed against the cabinet. Do not place the system against the cabinet.
The system may vibrate when it works.
c. The water pressure is instable. Check and confirm the water pressure is between 14.5 PSI
and 87 PSI. The sound will decrease when water pressure becomes stable.
•
Water Shortage Reminder
The front panel screen shows code E01, buzzer sounds 3 times.
a. Check if it is out of water, turn on feed water adapter or water supply valve.
b. The inlet water tubing is crimped. Check and remove crimps.
•
Booster Pump Overworked Reminder.
The front panel screen shows code E03, buzzer keeps beeping for 3 minutes.
a. Continuously dispensing water for more than 30 minutes. Power on the system again to
recover.
b. There is a leak at the tubing connection between the system and RO faucet. Turn off
the power. Check the tubing connection, make sure tubing is inserted into the quick-
connect fitting properly and firmly, and power on the system again.
•
TDS Reading Fluctuates When Dispensing Water
a. The TDS reading displayed is the TDS of flowing filtered water. Therefore, the content of
dissolved solids may vary slightly as water flows, causing the fluctuation of TDS reading.
b. The built-in TDS sensor has deviation, causing the fluctuation of TDS reading.
•
The Difference between the TDS Reading Tested by TDS Meter and the
Displayed Reading
a. The reading tested by TDS Meter is the TDS of static water in the container while the TDS
reading displayed by the system is the TDS of flowing water. As a result, the TDS readings
are different.
b. There are errors in TDS Meter tests.
•
Filtered Water from RO Faucet Tastes Like Tap Water
a. Incorrect tubing installation. Make sure the waste water tubing is not connected with RO
faucet.
b. The filters are not well installed. Check and make sure the filters are placed in properly.
c. Filter expires. Check the filter life indicators to confirm which filter needs to be replaced
and replace immediately.
