Possible Cause
Increase in product TDS
Carbon Post-Filter exhausted
Tank and appliance contaminated
Tank contaminated
Tank diaphragm failure
Carbon Post-Filter cartridge not flushed
completely
Dissolved air in feed water, which is
concentrated in product water
Increase in product TDS
Dissolved air in feed water, which is
concentrated in product water
Certain ice cube shapes trap more dissolved
air than others. The larger, more squared off
cubes are the clearest. Smaller, rounded
surface ice cubes are cloudier
Membrane fouled, hydrolyzed, ruptured, or
attacked by bacteria
Deformed or stretched O-Ring or housing not
tight
Dirt or debris plugging flow restrictor tube
Valve seat is defective
Debris is lodged in 3/8-inch tube from air gap
to drain
Fatigue or misuse
Fatigue or misuse
Fatigue
Fatigue
Tank may lose air over a period of time
Pressure exceeds diaphragm strength due to
combination of high feed pressure and low
precharge, or defective tank
Solution
See "High product water TDS"
Replace Carbon Post-Filter cartridge
Replace Pre- and Post-Filter, sanitize tank and
appliance
Sanitize tank
Replace tank and postfilter cartridges
Flush one or two tanks of product water
through Post-Filter
This condition usually clears up eventually as
the condition of feed water changes. Letting
water stand will allow dissolved air to dissipate

Change ice cube mold shape, make cubes
manually if using automatic. Let water sit to
release dissolved air before freezing
Replace membrane
Replace O-Ring and clean seating surface or
tighten housing
