Whirlpool Washer drn Error Code — What It Means
The drn code (sometimes displayed with F9 E1 on top-load models) indicates your Whirlpool washer has detected a long drain condition. The control board is seeing that the water level inside the tub is not dropping fast enough during the drain portion of the cycle, so it flags a drain-system fault rather than allowing the cycle to continue. This is a drain pump system problem, not a spin issue.
The machine is telling you that water is taking too long to leave the tub. The drain window has a time limit, and when that limit is exceeded the washer stops and throws the drn code to protect the motor and prevent flooding.
Common Causes
- Kinked or clogged drain hose The drain hose is pinched, twisted, or has an internal blockage that restricts water flow out of the washer.
- Drain hose installed incorrectly The hose is inserted too far into the standpipe (more than 4.5 inches), positioned too low (below 36 inches from the floor), or the end is taped over.
- Foreign object jamming the drain pump impeller Coins, socks, nails, or other debris have lodged in the pump housing or impeller, preventing it from spinning freely and moving water.
- Restriction in the tub-to-pump hose path Debris or a blockage has built up in the internal hose between the tub and the pump, slowing water flow.
- Failed or weak drain pump motor The pump motor is electrically open, seized, or running weakly and cannot generate enough pressure to move water out in the allowed time.
Step-by-Step Fix
- Power down the washer by unplugging it or turning off the circuit breaker for at least two minutes to clear the fault code and reset the control board.
- Check the external drain hose installation by inspecting the hose from the back of the washer to the standpipe or laundry sink for kinks, pinches, and blockages, and verify the hose end is higher than 36 inches from the floor and inserted no more than 4.5 inches into the standpipe.
- Run a drain test by restoring power, selecting a drain or spin cycle, and watching to see if water evacuates quickly or if the drn code returns.
- Access the drain pump by removing the rear service panel or lower front access (depending on your model) and inspecting the hose connection from the tub to the pump and from the pump to the drain outlet for obstructions.
- Inspect the pump impeller by disconnecting the hoses, removing any clamps, and checking inside the pump housing for coins, fabric, or other debris that could jam the impeller or prevent it from turning.
- Clear any obstruction you find in the hoses or pump housing, reassemble the connections with new clamps if needed, and run another drain test to confirm water evacuates normally.
- Replace the drain pump assembly if the motor hums but does not spin the impeller, if it is electrically open when tested with a multimeter, or if the housing is cracked or leaking.
Parts Often Needed
| Part | Notes |
|---|---|
| Drain pump assembly | Amazon | Choose the pump that matches your Whirlpool washer model number if the motor is weak, seized, or electrically failed. |
| Drain hose | Amazon | Replace if the original hose is cracked, kinked beyond repair, or has an internal clog you cannot clear. |
When to Call a Pro
Call a qualified appliance technician if you’ve checked the drain hose installation and cleared obvious blockages but the drn code still appears after a reset. A pro can safely disassemble the pump housing, test the motor windings with a multimeter, trace internal hose paths that are difficult to reach, and replace the pump assembly or other components without risking water leaks or electrical faults. If your washer is still under warranty, contact Whirlpool or an authorized service provider before opening any panels to avoid voiding coverage.
