Troubleshooting - EcoWater ERO-375 Owner's Manual

1. AT LEAST every 6 months, replace the prefilter and postfilter cartridges or when faucet LED flashes yellow or Wi-Fi alert indicates "Replace filters".
2. Replace the RO membrane cartridge when the percent rejection of total dissolved solids (TDS) is less than shown in the specifications (see B, below)
or when faucet LED flashes red or Wi-Fi alert indicates "Replace membrane".
3. Replace the batteries once per year or when Wi-Fi alert indicates "Replace batteries".
A. Slow Making of Product Water: Replace the prefilter cartridge. If the
production rate does not improve, replace the post filter cartridge and RO
membrane cartridge.
B. High Total Dissolved Solids (TDS) in Product Water: If water quality is in
question, contact your local dealer for testing. It is important to test both
the treated and untreated water to determine system performance. If the
TDS is not within the system's performance guidelines, replace the pre-
filter, post filter and RO membrane cartridges.
PROBLEM
Chlorine taste and/or odor
in the RO product water.
Other taste and/or odor.
System makes product
water too slowly.
System makes lower
amount of product water
than usual.
High total dissolved solids
(TDS) in product water -
flashing red LED.
Water leaking from faucet
airgap hole.
Continual water flow to
drain.
Faucet LED indicator light
does not function after bat-
tery change.
Continual high water flow
to drain and no product
water.

If any of the following occur before the 6 months, replace as directed.
OTHER TROUBLESHOOTING
CAUSE
The amount of chlorine in your water sup-
ply exceeds maximum limits, and has
destroyed the RO membrane.
The prefilter is no longer removing chlorine
from the water supply.
Post filter expended.
RO membrane cartridge expended.
Contamination in product water storage.
Water supply to the RO system not within
specifications.
Prefilter or RO membrane cartridges
plugged with sediments or fouled.
Flow Control Insert plugged.
Storage tank air-charge less than 5 - 7 psi.
Water supply to the RO system not within
specifications.
RO membrane cartridge expended.
Drain side of faucet airgap (3/8" tubing)
plugged, restricted, or incorrectly connected
to drain point.
Check valve or automatic shutoff assembly
plugged, restricted or parts worn.
Battery dead.
Battery installed incorrectly.
Missing flow restrictor in red drain tube or
its corresponding port.
C. Chlorine Taste and/or Odor: Replace the prefilter, post filter and RO
membrane cartridges.
CORRECTION
If the water supply contains more than 2.0 ppm of chlorine,
additional filtering of the water supply to the RO is needed.
Correct this condition before doing maintenance on the RO
system.
Replace the prefilter, post filter and RO membrane cartridges.
Replace the post filter cartridge. If taste and odor persists,
replace the prefilter cartridge and RO membrane cartridge.
Use sanitizing procedures. Replace the post filter cartridge.
Increase water pressure, precondition the water, etc., as need-
ed to conform before doing maintenance on the RO system.
Replace the prefilter cartridge. If rate does not increase,
replace the postfilter cartridge and RO membrane cartridge.
Check and clean Flow Control Insert.
Open RO faucet and drain tank until flow slows to a drip.
Keep faucet open and check tank pressure. If low, pressurize
to 6 psi. Close faucet to refill the tank.
Increase water pressure, precondition the water, etc., as need-
ed to conform before doing maintenance on the RO system.
Replace the prefilter, postfilter and RO membrane cartridges,
flow control, and screen.
Inspect and eliminate restriction or plug. Refer to installation
instructions for proper drain connection.
Clean, repair or replace as needed.
Replace with new battery.
Install battery correctly.
Replace flow restrictor.
