What Does Error CHECK-WATER-LIGHT-BLINKING Mean?

The CHECK-WATER-LIGHT-BLINKING error on your Scotsman ice maker indicates a lack of water in the reservoir or an issue with sensing water. This safety mechanism halts ice production to prevent damage. The unit will attempt to restart automatically when the water supply is restored. Ensure the water supply valve is open, check for kinks or blockages in the inlet line, and inspect any filters for clogs.

Common Symptoms:

  • Check Water light blinking red
  • No ice production while light is blinking
  • Machine halts ice making due to insufficient water detected

Possible Causes

  • Lack of water in the reservoir (insufficient water supply) (high)
  • Water supply issue due to restricted flow (e.g., clogged filter, low pressure) (medium)

How to Fix Error CHECK-WATER-LIGHT-BLINKING

DIY Fix Verify Water Supply and Restore Flow

  1. Ensure the water supply valve to the ice maker is fully open.
  2. Check that the inlet water line isn’t kinked or blocked.
  3. If a water filter is installed, inspect and replace it if clogged.
  4. Allow the machine a few minutes to fill the reservoir and see if the Check Water light stops blinking.

DIY Fix Reset the Machine After Water is Restored

  1. If the Check Water light was blinking due to lack of water, restore water supply.
  2. Turn the ice maker off, wait 10–20 seconds, then turn it back on to clear the error and allow a fresh fill cycle.
  3. Observe if ice production resumes and the light clears.

Technician Only Inspect Water Inlet Valve and Sensors

  1. Check the inlet water solenoid valve for proper operation and measure coil resistance.
  2. Examine water conductivity and level sensing components for scale build‑up and clean or replace sensors as needed.
  3. Verify water pressure at the machine meets manufacturer specifications.

Parts needed: Water inlet valve, Water level sensor, Water filter (if applicable)

🛑 When to Call a Pro:
  • If water supply is confirmed good but the Check Water light continues blinking after cleaning and resets.
  • If water sensors or inlet valve are suspected faulty or water pressure can’t be verified.
