Seasoning an ice maker means running the first several batches of ice and discarding them to flush out dust, plastic shavings, and any bitter-tasting chemicals left from manufacturing. This process typically takes 24 to 48 hours and is essential for both new machines and units that have been idle for a long time.
Seasoning an ice maker involves discarding the first 3 to 5 ice batches to remove residues and ensure clean, high-quality ice. This process applies to portable, built-in, and countertop models.
- What is seasoning?: Seasoning is the process of discarding the first several ice batches from a new or cleaned ice maker to flush out manufacturing residues and stale water.
- Why is seasoning necessary?: New ice makers often contain plastic dust, metal shavings, or refrigerant oil residue that can affect ice taste and clarity.
- How many batches to discard?: Most manufacturers recommend discarding 3 to 5 full ice batches, or the first 24 hours of production.
- Does seasoning apply to all ice makers?: Yes, including portable countertop units, built-in undercounter models, and ice machines in refrigerators.
Why Seasoning Matters
When an ice maker is manufactured, residual oils, plastic particles, and dust can accumulate inside the water lines, mold, and storage bin. Even if you clean the machine with a sanitizer, these particles can be trapped and later released into your ice. Seasoning ensures that the first ice produced—which may taste like plastic or chemicals—is thrown away, leaving you with pure, clear ice.
Additionally, if your ice maker has been sitting unused for more than a week, stale water can develop a musty odor. Running and discarding several batches refreshes the water system and prevents off-flavors from affecting your drinks.
Step-by-Step Seasoning Process
- Install and clean first: Follow the manufacturer’s initial cleaning instructions. For most units, this means wiping the interior with a mild detergent, rinsing, and running a vinegar or cleaning solution cycle if recommended.
- Connect water supply: Ensure the water line is properly connected and the unit is level. Turn on the water supply and check for leaks.
- Start the ice maker: Press the power button and allow the machine to begin its first cycle. The first batch may take 60 to 90 minutes depending on the model.
- Discard the first 3-5 batches: Once the bin fills, empty it completely. Do not use any of this ice for consumption. Repeat this step until the ice appears clear and has no odor.
- Wipe down after seasoning: After discarding the final batch, wipe the bin and scoop with a clean cloth to remove any remaining residue.
How Many Batches Are Enough?
Most manufacturers recommend discarding the first 3 to 5 full ice batches. For a typical countertop ice maker that produces 24 cubes per cycle, that means discarding 72 to 120 cubes. For larger built-in units, the number of cycles may be similar, but the volume of ice discarded is greater. In general, if the ice still looks cloudy or has a faint plastic smell after 3 batches, continue seasoning for 2 more batches. The ice should be crystal clear and odorless before you start using it.
Some machines have a ‘self-cleaning’ or ‘flush’ mode that automatically cycles water through the system. If yours has that, run it once before starting normal production.
What About Portable or Countertop Ice Makers?
Portable ice makers, such as those from brands like Igloo, Frigidaire, and GE, require the same seasoning process. Because these units often have smaller water reservoirs, you may need to empty the basket after every cycle. Discard the first 5 to 6 full baskets. Also, note that portable ice makers typically produce bullet-shaped or nugget ice, which can trap more residue in the mold. Seasoning is especially important for these to avoid a chemical aftertaste.
After seasoning, you can enjoy fresh ice without any off-flavors. If you notice a persistent taste after seasoning, check your water quality or consider using filtered water.
When to Re-Season Your Ice Maker
You should re-season your ice maker if it has been unused for more than two weeks, after a deep cleaning, or after moving the unit. Stagnant water can develop biofilm and odors, so running and discarding a few batches will refresh the system. Additionally, if you change your water filter or switch from hard to soft water, a quick seasoning cycle (1-2 batches) helps flush out any initial impurities.
Most manufacturers suggest a full cleaning every 6 months, followed by a seasoning cycle of 3 batches. This keeps your ice maker running efficiently and your ice tasting great.
Pro Tips
- Use filtered or distilled water for the first few batches to minimize mineral scale and improve ice clarity.
- Place a clean towel under the ice maker to catch any drips or spills during the seasoning process.
- Label the first batches of ice with a sticky note so family members don’t accidentally use them.
- If your ice maker has a ‘clean’ indicator light, wait until it turns off before starting the seasoning process.
Common Mistakes to Avoid
- Tasting the first batch of ice to check for off-flavors—always discard without tasting, as residues can be irritating.
- Using the ice for cooling beverages before seasoning is complete, which can ruin the flavor of your drinks.
- Skipping the initial cleaning step and going straight to seasoning, which leaves behind stubborn residues.
- Not discarding enough batches—if ice still smells like plastic after 3 batches, continue until odor is gone.
FAQ
Can I speed up the seasoning process?
No, the seasoning process requires each batch to fully freeze and then be discarded. Speeding it up by using warm water or interrupting cycles can leave residues behind. Allow the machine to run its normal cycles.
Do I need to season a built-in refrigerator ice maker?
Yes, all new ice makers should be seasoned. For refrigerator ice makers, discarding the first 3-5 batches (about 24 hours of production) is recommended. Check your refrigerator manual for specific guidance.
What if my ice maker still tastes like plastic after seasoning?
If the plastic taste persists, the water supply may be the issue. Try using filtered water or descale the unit with a vinegar solution. If the taste continues, contact the manufacturer, as there may be a manufacturing defect.
The Bottom Line
Seasoning your ice maker is a simple but crucial step that ensures your ice is clean, clear, and free of off-flavors. By discarding the first few batches, you remove manufacturing residues and stale water. Make this a habit after any cleaning or prolonged idle period, and your ice maker will deliver fresh-tasting ice for years to come.
