What Replace Filter light means

On KitchenAid undercounter freestanding ice makers with a water filter, such as the KUIX535HPS, KUIX335HPS or KUID308HPS, the "Replace Filter" light comes on only after nine months or 2,000 gallons of water use. Replace the filter every nine months, or when the ice rate drops. With very hard water, plan to do it sooner. The light is a reminder, not a breakdown.

Common causes of Replace Filter light

  • Nine months or 2,000 gallons of water have passed
  • A clogged filter is slowing water flow and ice production
  • Very hard water is exhausting the filter early
✓ One safe check you can try

1. Buy the correct replacement filter for your model. 2. Turn off the water supply to the ice maker if your filter requires it. 3. Swap the filter as the instructions for your model show. 4. Reset the filter light as directed. 5. Discard the first ice. 6. If the light stays on or ice output stays low, call us.

! Why to stop there
  • Changing a filter is a simple owner task
  • We step in only if the light stays on or water flow is still weak
  • Written price first and a 30-day workmanship warranty on repairs
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Replace Filter lightReplace Filter light questions
How often should I change the filter?

Every nine months, or when the ice rate drops. With very hard water, replace it sooner.

The light is on but I just changed the filter. Why?

The counter probably was not reset. Follow the reset step for your model.

Will an old filter hurt ice production?

Yes. A clogged filter reduces water flow and can slow ice making noticeably.
