Amana dLO Error Code — What It Means
The dLO or Ld code on Amana top-load washers signals a long-drain fault. The control board detects that the washer is taking too long to pump out water during the drain cycle. This is a drain-system problem, not a fill issue. The washer may pause mid-cycle or fail to complete the spin because standing water remains in the tub.
Common Causes
- Drain hose inserted too far into standpipe If the hose extends more than 4.5 inches into the drainpipe, it can create a siphon or restrict flow and trigger the long-drain fault.
- Kinked or clogged drain hose A bent, twisted, or debris-filled hose slows water discharge and causes the control to see a drain timeout.
- Hose taped or sealed into the standpipe Sealing the hose end removes the air gap needed for proper drainage and can create a vacuum that slows or stops flow.
- Standpipe too low Amana requires the drainpipe to be at least 39 inches high to prevent siphoning and make sure proper pump performance.
- Blocked pump inlet or debris in drain path Coins, socks, lint, or small objects can lodge in the pump inlet or filter and restrict water flow enough to trip the code.
- Failed drain pump If the hose installation and drain path are clear but the code persists, the pump itself may be weak or inoperative.
Step-by-Step Fix
- Unplug the washer and turn off the water supply before beginning any inspection or repair work.
- Check the standpipe height and hose insertion depth. The drainpipe must be at least 39 inches high and the drain hose should not extend more than 4.5 inches into it. Pull the hose back if needed and confirm the hose end is not taped or sealed into the pipe.
- Inspect the drain hose for kinks, twists, or clogs. Straighten any bends and flush the hose with water to clear blockages. Verify the hose uses the plastic drain-hose form to hold its shape at the standpipe connection.
- Remove the lower front or rear access panel (model-dependent) and locate the drain pump. Disconnect the drain hose at the pump outlet and check for trapped coins, socks, or lint in the hose connection and pump inlet.
- Test the pump manually if accessible. With the hose disconnected, run a drain or spin cycle and watch for strong water flow from the pump. Weak or no flow indicates a failed pump.
- Replace the drain pump if the hose installation is correct, the drain path is clear, and flow is weak or absent. Follow your model’s service manual to disconnect the wiring harness and mounting hardware.
- Reassemble the washer, restore power, and run a rinse-and-spin test cycle to confirm the code clears and water drains completely within the normal cycle time.
Parts Often Needed
| Part | Notes |
|---|---|
| Drain pump assembly | Amazon | Match to your exact Amana model number. Most common replacement when hose and path are clear. |
| Drain hose | Amazon | Replace if kinked, cracked, or permanently clogged. make sure correct length and use the included hose form. |
When to Call a Pro
If you have corrected the hose installation, cleared the drain path, and tested the pump but the dLO code returns, call a qualified appliance technician. The issue may involve the control board, pressure switch, or wiring that requires diagnostic tools and schematic access. Also call a pro if you are uncomfortable accessing internal components, handling electrical connections, or working around standing water in the tub.
