Ice maker indicates drain error; water remains in reservoir or sump

Safety: Unplug the unit before working on the drain system. Water may spill; have towels ready.

• Inspect external drain: Check the drain hose from the ice maker to the household drain. Straighten kinks and clear any visible clogs.
• Clean internal drain: Remove the front panel and access the internal drain area. Clear debris, scale, or ice from the drain opening and sump.
• Test drain pump: During a drain cycle, listen for the pump. If silent, test for voltage at the pump terminals. If voltage is present but the pump does not run, replace the pump.
• Check check-valve: Some KitchenAid models use a drain check valve. Remove and clean or replace if stuck.
• Run a test cycle: After clearing and repairs, run a clean or drain cycle to verify proper water removal.
