E17 error; unit fails to drain meltwater or cleaning solution, water remains in the sump.

Safety first: Unplug the ice maker and place a shallow pan or towels under the drain area.

• Step 1 – Inspect external drain: Ensure the external drain hose is not kinked, elevated too high, or blocked at the outlet.
• Step 2 – Clean internal drain: Access the internal drain port and hose. Flush with warm water to remove scale and debris.
• Step 3 – Check drain pump (if equipped): For Teendow models with a pump, remove the pump cover and inspect the impeller for obstructions. Clean thoroughly.
• Step 4 – Test pump: With power briefly restored, listen for pump operation during a drain cycle. If silent and wiring is intact, the pump motor is likely failed.
• Step 5 – Replace pump or hose: Install a Teendow-compatible drain pump or replace the drain hose if damaged.
