Amana Washer DRN Error Code — What It Means
The DRN code on an Amana washer means the machine has detected that it is not draining properly. Amana states this can sometimes be an installation problem rather than a failed part. The washer has sensed water is still present after the drain cycle, triggering the fault to protect the machine and your laundry.
Common Causes
- Kinked or clogged drain hose A twist, pinch, or blockage in the drain hose prevents water from leaving the tub.
- Incorrect drain hose installation The hose may be inserted too far into the standpipe or routed below the proper height, causing siphoning or air-lock.
- Standpipe height or sealing issue If the drain hose end is below 36 inches from the floor or the standpipe opening is sealed airtight, drainage fails or siphons.
- Drain pump restriction or failure Debris in the pump path or a worn pump impeller stops the machine from pumping water out.
- Wiring harness or control fault Damaged wires or a control board issue can prevent the pump from receiving power, even when the drain path is clear.
Step-by-Step Fix
- Unplug the washer and pull it away from the wall so you can access the rear drain hose and connections safely.
- Inspect the drain hose for kinks, sharp bends, or clogs by disconnecting it from the standpipe and checking both ends.
- Verify installation geometry by confirming the drain hose end sits higher than 36 inches from the floor and does not extend more than 4.5 inches into the standpipe.
- Confirm the standpipe is not sealed airtight around the drain hose, use the hose form to secure the hose loosely and allow air to enter the pipe.
- Run a Drain/Spin cycle after correcting any hose or setup issues and listen for the drain pump to hum or run.
- Check the drain pump for blockage by accessing the pump filter or coin trap (if your model has one) and removing any debris or foreign objects.
- Inspect the pump assembly, wiring harness, and control if the drain path is clear but the pump does not hum or run, testing for power to the pump and continuity in the harness.
Parts Often Needed
| Part | Notes |
|---|---|
| Drain pump assembly | Amazon | Required if the pump hums but does not move water or if the impeller is damaged. |
| Drain hose | Amazon | Replace if kinked permanently or split along its length. |
| Wiring harness | Amazon | Needed if wires to the pump are damaged, corroded, or shorted. |
When to Call a Pro
If you have corrected the drain hose installation and cleared any visible blockages but the washer still displays DRN and does not drain, call a technician. Diagnosing pump electrical issues or control board faults requires a multimeter and knowledge of the washer’s wiring schematic. A professional can safely test pump voltage, check harness continuity, and determine whether the control needs replacement.
