DL is a front-load code on Speed Queen washers; the display alternates Er and dL. In Alliance Laundry's error list for home and light-commercial controls it is the fatal door-lock error: the control saw the door unlocked while a cycle was running, which it treats as unsafe, so everything stops and the error stays until power is cycled. Two related codes narrow things down – d1 when the door won't lock within 20 seconds, and dU when it won't unlock after the drum stops. Speed Queen's own corrective actions are to inspect the door lock and latch for damage and the lock harness for breaks or disconnection. Top-load Speed Queen washers don't use this code.
How it looks on the display
Model families & display variants
| Model family | Shows | Note |
|---|---|---|
| Speed Queen front-load washers (e.g. FF7) | Er / dL | Fatal door-lock error: door sensed unlocked during a running cycle. Power down to clear. |
| Same models – lock timeout | Er / d1 | Door didn't lock within 20 seconds; clears once the door locks or is opened. |
| Same models – unlock timeout | Er / dU | Door didn't unlock 20 seconds after the drum stopped. Removing power for 3 minutes lets the lock release; push the door in, then pull. |
| Speed Queen top-load washers | none | Top-loaders don't report dL; lid problems show differently. |
Safety first · Consult a professional
Unplug the washer before touching the lock, latch or wiring. Never force a locked door while the drum is turning or there is water above the door opening.
- Unplug the appliance or switch off the breaker before opening any panel. Mains voltage can kill.
Symptoms
- Er and dL alternating on the display and the cycle stopped mid-way
- Door lock clicks, then the washer shuts everything off
- Error returns on the next cycle after a power reset
- Door hook looks bent or the door sags on its hinge
- Pulling on the handle during a cycle triggered the stop
Possible causes
Ranked by how often each cause is behind this code (editorial estimate).
- Door lock assembly worn or failing (switch contacts or lock mechanism)
- Door latch (hook) damaged, loose or misaligned from a sagging hinge
- Lock harness damaged, chafed at the door boot or disconnected
- Door pulled or bumped while locking or locked
- Overloaded drum pressing the door outward
- Control fault in the lock circuit
Fix it step by step
Cycle power
Speed Queen's list says the fatal dL error only clears when power is cycled. Turn the washer off, unplug it for a minute, and plug it back in.
Look at the latch
Open the door and inspect the hook that enters the lock. It should be straight, tight on the door and meet the lock slot centered. A door that drops when you lift it slightly has a loose or worn hinge.
Tools: Flashlight
Check the load and the seal
An overstuffed drum or a bulky item pressing on the glass keeps the door from seating. Remove some laundry and make sure nothing is caught between the door and the boot.
Inspect the lock and harness
With the washer unplugged, remove the screws holding the lock from the front, ease it out behind the boot and look for a cracked housing, burn marks or a loose plug. Follow the harness for rubbed-through insulation.
Tools: Screwdriver, Flashlight
Continuity test (experienced DIY)
Using the wiring diagram for your model, check the lock's switch with a multimeter in locked and unlocked states. A switch that doesn't change state, or reads intermittently when tapped, means the lock should be replaced.
Tools: Multimeter
How to reset DL
- Turn the washer off and unplug it to clear Er dL – a keypad press won't clear the fatal error.
- Plug back in and close the door firmly.
- Start a short cycle and listen for the lock engaging cleanly.
- If dL returns, don't keep restarting; replace the lock or have it checked.

When to call a technician
Get a technician if dL comes back after a new lock, the harness is damaged near the door boot, or the door won't release with water in the drum. Speed Queen's warranty on home models typically covers labor for several years, so check coverage before buying parts.
Frequently asked questions
What's the difference between dL, d1 and dU?
dL means the door was sensed unlocked while running – a fatal error cleared by cycling power. d1 means the door didn't lock within 20 seconds, and dU means it didn't unlock 20 seconds after the drum stopped.
How do I get my clothes out if the door won't unlock?
Wait until the drum has stopped and there's no water above the door. Removing power for 3 minutes lets the lock release; press the door inward, then pull the handle.
Can pulling on the door during a cycle cause this?
Yes. Pulling while the door is locking or locked can make the control see an unlocked state. Let the cycle finish or pause it and wait for the unlock.
Does my Speed Queen top-loader have a DL code?
No. Alliance's code list shows dL only for front-load washers.
