Troubleshooting - Whirlpool WHER25 Installation And Operation Manual

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 mem-
brane.
Cause: The prefilter is no longer reducing chlo-
rine from the water supply.
Problem: Other taste and/or odor.
Cause: Postfilter expended.
Cause: Reverse Osmosis membrane cartridge
expended.
Cause: Contamination in product water storage tank. Correction:
Cause: System contamination.
Problem: System makes product water too slowly.
Cause: Water supply to the Reverse Osmosis sys-
tem not within specifications.
Cause: Prefilter or Reverse Osmosis membrane
cartridges plugged with sediments.
Problem: System makes lower amount of product water than usual.
Cause: Storage tank air-charge less than
5-7 psi.
Problem: High total dissolved solids (TDS) in product water
Cause: Water supply to the Reverse Osmosis sys-
tem not within specifications.
Problem: Continual water flow to drain and no product water.
Cause: Missing flow control insert in red drain tube
or its corresponding port.

Troubleshooting

Correction: If the water supply contains more than 2.0 ppm of chlorine, addition-
al filtering of the water supply to the Reverse Osmosis is needed.
Correct this condition before doing maintenance on the Reverse
Osmosis system.
Correction: Replace the prefilter, postfilter and Reverse Osmosis membrane
cartridges. See Page 20.
Correction: Replace the post filter cartridge. If taste and odor persists, replace
the prefilter cartridge and Reverse Osmosis membrane cartridge.
See Page 20.
Use sanitizing procedures. Replace pre and post filter cartridge. See
page 16.
Correction: Sanitize entire system. Call 1-866-986-3223 for instructions.
Correction: Increase water pressure, precondition the water, etc., as needed to
conform before doing maintenance on the Reverse Osmosis sys-
tem.
Correction: Replace the prefilter cartridge. If rate does not increase, replace the
postfilter cartridge and Reverse Osmosis membrane cartridge. See
Page 20.
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.
Correction: Increase water pressure, precondition the water, etc., as needed to
conform before doing maintenance on the Reverse Osmosis sys-
tem.
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 prefilter, post filter and
RO membrane cartridges.
Correction: Replace flow control insert. See Page 21.
