Sarah Mitchell Key Takeaways
- Replace the water filter every 6 months to ensure clean-tasting ice and proper water flow.
- Run the built-in cleaning cycle every 3-6 months to remove mineral scale and bacteria.
- Clean condenser coils every 6 months to maintain cooling efficiency and ice production speed.
- Flush the drain line annually to prevent clogs and stale-water odors.
- Discard the first batch of ice after any period of non-use or after cleaning.
The Bottom Line
Regular maintenance keeps your Jenn-Air ice maker producing clean, clear ice at full capacity. The water filter and cleaning cycle are the two most important items on the schedule.
Maintaining Your Jenn-Air Ice Maker
Whether your Jenn-Air ice maker is built into a refrigerator column or is a dedicated under-counter unit, it needs regular maintenance to produce clean, clear, fresh-tasting ice. Minerals in your water supply, bacteria from ambient air, and dust on the condenser coils all affect ice quality and production rate over time. This maintenance schedule addresses each factor and keeps your ice maker running at full capacity.
Water Filter Replacement
The water filter is the first line of defense for ice quality. It removes chlorine, sediment, and other contaminants that affect taste and clarity. Jenn-Air recommends replacing the filter every six months, and most models have a status indicator that tracks usage and alerts you when replacement is due. In areas with hard water or well water, more frequent replacement may be necessary.
Always use a Jenn-Air or Whirlpool-approved replacement filter. Third-party filters may not meet the same filtration standards and can affect water flow to the ice maker, potentially triggering the FL diagnostic code. After replacing the filter, discard the first two batches of ice — they may contain carbon fines from the new filter that are harmless but unappealing.
Running the Cleaning Cycle
Jenn-Air under-counter ice makers and many refrigerator-integrated ice makers include a built-in cleaning cycle. This cycle circulates a cleaning solution — typically a nickel-safe ice machine cleaner — through the water system, over the evaporator plate, and into the drain to dissolve mineral scale and sanitize surfaces. Run this cycle every three to six months depending on your water hardness and usage level.
To run the cleaning cycle, consult your model's owner's manual for the specific button sequence. Generally, you will add the recommended amount of ice machine cleaner to the water reservoir, initiate the cleaning mode, and let the cycle complete — which typically takes 30 to 45 minutes. After the cleaning cycle finishes, run two to three normal ice production cycles and discard the ice before using any for consumption.
Condenser Coil Cleaning
The condenser coils on your ice maker work the same way as those on a refrigerator — they release heat from the refrigeration system. Dust and grease buildup insulates the coils and reduces cooling capacity, which means slower ice production and higher energy consumption. Every six months, access the condenser area — usually behind a front grille on under-counter models or at the bottom of a refrigerator column — and clean the coils with a brush and vacuum.
Drain Line Maintenance
Under-counter Jenn-Air ice makers have a drain line that carries melt water and cleaning solution out of the unit. Over time, mineral deposits and biofilm can accumulate inside this line, causing slow drainage and unpleasant odors. Once a year, flush the drain line with a solution of warm water and a tablespoon of baking soda. If the line is severely restricted, a pipe cleaner or flexible brush can break up the buildup before flushing.
Exterior and Bin Cleaning
Clean the ice storage bin monthly with warm water and baking soda. Do not use soap or chemical cleaners inside the bin, as residue can transfer to the ice and affect taste. Wipe the exterior surfaces with a damp cloth and an appropriate cleaner for the finish — stainless steel cleaner for RISE models or a soft damp cloth for NOIR finishes. Keep the area around the ice maker free of clutter to ensure proper ventilation.
After Extended Non-Use
If your ice maker has been turned off for more than two weeks — such as during a vacation — run a cleaning cycle before resuming normal use. Discard the first three batches of ice to flush the system. Check the water filter status indicator and replace the filter if it was near end of life before the idle period. Standing water in the system during downtime can develop bacteria and off-flavors that a cleaning cycle effectively addresses.
