Huebsch QN Washer-Extractor Error Code E dL1: Door Lock Non-Fatal

What does Huebsch error code E dL1 mean?

Before a QN washer-extractor starts a cycle, the output board commands the door lock and then waits for the lock and the door switch to confirm that the door is shut and held. If it does not get that, it keeps retrying for 60 seconds before it gives up and posts E dL1. Operators see a machine that will not begin a cycle after the door is shut. Because the error is called non-fatal, the machine may try again, but a door that will not lock often means a misaligned latch, an obstruction at the door or a lock that is not responding. The manual's causes are a door out of alignment or an object caught at the door seal, a lock solenoid or latch that fails to engage the door, a door switch that does not report the door as shut, and a broken wire or loose plug on the lock circuit. Nothing is moving when this code appears, since the cycle has not begun. That makes it a safer code than E dL, and an owner can reasonably re-close the door once.

Affected models and control systems

E dL1 is listed for CHM1792C-family Huebsch QN washer-extractors (20 to 100 lb) with the front-end control and output board. Other controller generations use other door lock codes.

Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.

What you may notice

• Cycle will not begin after the door is shut
• E dL1 appears after about a minute
• Lock does not click when the door closes

Possible causes

Listed in Huebsch's documentation

• Door misaligned or an object caught at the door seal
• Lock solenoid or latch that fails to engage
• Door switch that does not report the door as shut
• Broken wire or loose plug on the lock circuit

Other likely causes — what usually sits behind error code E dL1 on this control. A technician confirms which one it is before any part is replaced.

• Linen caught in the seal on a loaded door
• Latch tongue bent after the door was slammed
• Lock connector worked partly out of its socket

Safe checks before calling for service

How a technician diagnoses error code E dL1

1. Read the code and note whether the lock clicks when commanded.
2. Inspect door alignment, seal and latch tongue.
3. Test the door switch and the lock solenoid with a meter.
4. Check the lock circuit wiring and plug for breaks.
5. Replace the lock or switch that fails, and run a test start.

How error code E dL1 differs from similar codes

E dL1 is a door that would not lock before the cycle. E dL2 is a door that would not unlock after it, and E dL is the fatal case where it unlocked mid-run.
