Kenmore REVERSE OSMOSIS 625.38556 - Manual (Page 24)

Troubleshooting
Problem: Chlorine taste and/or odor in the RO product water.
Cause: The level of chlorine in your water
supply exceeds maximum limits, and
has destroyed the Reverse Osmosis
membrane.
Correction: If the water supply contains more than 2.0 ppm of chlorine,
additional filtering of the water supply to the Reverse Osmosis is
needed. Correct this condition before doing maintenance on the
Reverse Osmosis system.
Cause: The prefilter is no longer reducing
chlorine from the water supply.
Correction: Replace the prefilter, postfilter and Reverse Osmosis membrane
cartridges. See page 20.
Problem: Other taste and/or odor.
Cause: Postfilter expended.
Reverse Osmosis membrane cartridge
expended.
Correction: Replace the post filter cartridge. If taste and odor persists,
replace the prefilter cartridge and Reverse Osmosis membrane
cartridge. See page 20.
Cause: Contamination in product water
storage tank.
Correction: Use sanitizing procedures. Replace pre and post filter cartridge.
See pages 16 & 20.
Cause: System contamination. Correction: Sanitize entire system. Call 1-800-426-9345 for instructions.
Problem: System makes product water too slowly.
Cause: Water supply to the Reverse Osmosis
system not within specifications.
Correction: Increase water pressure, precondition the water, etc., as needed
to conform before doing maintenance on the Reverse Osmosis
system.
Cause: Prefilter or Reverse Osmosis membrane
cartridges plugged with sediments.
Correction: Replace the prefilter cartridge. If rate does not increase, replace
the postfilter cartridge and Reverse Osmosis membrane cartridge.
See page 20.
Problem: System makes lower amount of product water than usual.
Cause: Storage tank air-charge less than
5-7 psi.
Correction: Open Reverse Osmosis 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.
Problem: High total dissolved solids (TDS) in product water.
Cause: Water supply to the Reverse Osmosis
system not within specifications.
Correction: Increase water pressure, precondition the water, etc., as needed
to conform before doing maintenance on the Reverse Osmosis
system.
Correction: Send treated and untreated water samples to a water analysis
lab 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: Continual water flow to drain and no product water.
Cause: Missing flow control insert in red drain
tube or its corresponding port.
Correction: Replace flow control insert. See page 21.
