Safety first: Unplug the unit before working on the pump or hoses.

Step 1 – Verify pump mode: Ensure the pump function is enabled (if your Danby model has a pump button) and that the discharge hose is connected to the pump outlet, not the gravity drain.
Step 2 – Check hose routing: Confirm the hose runs upward only within the maximum lift height specified and then slopes down. Remove any kinks or clogs.
Step 3 – Clean pump intake: Access the internal pump reservoir and clear any slime or debris from the intake screen.
Step 4 – Test pump operation: With the unit reassembled, fill the bucket area and enable pump mode. Listen for the pump motor. If silent, the pump or its wiring may be faulty.
Step 5 – Replace pump assembly: Remove and replace the internal pump with a Danby-compatible assembly, ensuring all seals and clamps are secure.

When to call a technician: Pump replacement involves water and electrical components; professional service is recommended if you are unsure.
