Troubleshooting, Cont.
Problem Possible Cause Solution
Bad tasting water Increase in product TDS See “High product water TDS”
Carbon Post-Filter exhausted Replace Carbon Post-Filter cartridge
Tank and appliance contaminated Replace Pre- and Post-Filter, sanitize tank and
appliance
Tank contaminated Sanitize tank
Tank diaphragm failure Replace tank and postfilter cartridges
Carbon Post-Filter cartridge not flushed
completely
Flush one or two tanks of product water
through Post-Filter
Cloudy water Dissolved air in feed water, which is
concentrated in product water
This condition usually clears up eventually as
the condition of feed water changes. Letting
water stand will allow dissolved air to dissipate
Cloudy ice cubes Increase in product TDS See “High product water TDS”
Dissolved air in feed water, which is
concentrated in product water
Contact your local Hague dealer
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
Change ice cube mold shape, make cubes
manually if using automatic. Let water sit to
release dissolved air before freezing
RO membrane is bad Membrane fouled, hydrolyzed, ruptured, or
attacked by bacteria
Replace membrane
Pre- or Post-Filter leaks

Deformed or stretched O-Ring or housing not
tight

combination of high feed pressure and low
precharge, or defective tank
Replace tank
