Speed Queen Washer and Dryer Error Code oFF: Alarm Shutdown
OFF is the shutdown stage of the break-in alarm on Quantum frontload and topload washers and on the single and stacked dryer control, where it reads OFF. The machine stopped taking money after door or coin vault switch trouble. Close and latch the coin vault door, check that the machine door is shut, never bypass a switch, post an out-of-service sign and book service.
Medium: the machine is out of service and takes no money until the switch trouble is corrected.

What does Speed Queen error code OFF mean?
The break-in alarm has stages. First the control shows the alarm message when a door or coin vault switch reports an opening it did not expect. If the condition is not cleared, the control goes further and shuts the machine out of service, showing oFF on washers and OFF on the dryer control. In a laundromat that means the machine stopped taking money after door or coin vault switch trouble. It is a security response to switch readings, not a heat, water or gas problem, and the machine stays out of service. The manual lists a coin vault door left unclosed or unlatched, a door switch that reports open when it is not, a damaged wire on a door or vault switch, and a control that misreads a switch after an alarm. Closing and latching the vault, and shutting the machine door, is the safe first step. If the shutdown remains, a technician checks the switches and wiring, since an unlatched vault is not always the only reason.

- The control misreads a switch after an alarm
Other likely causes — what usually sits behind error code OFF on this control. A technician confirms which one it is before any part is replaced.
- A vault door that was opened for collection and not re-latched
- Switch contacts worn from heavy daily use
Safe checks before calling for service
- Close and latch the coin vault door, and make sure the machine door is shut.
- Never bypass a door switch.
- On a dryer, if you smell gas, leave and call the gas utility from outside.
- Post an out-of-service sign and book service with us.
How a technician diagnoses error code OFF
- Read the display and confirm the model and control.
- Check the vault latch, its switch and alignment.
- Inspect the door switch and its wiring for damage.
- Test the switches with a meter and clear the alarm state per the procedure.
- Replace the switch or wiring only after the test, then confirm the machine accepts payment.
- Door switches and their wiring sit beside 120 V circuits and, on dryers, gas-fired parts.
- Clearing the alarm without finding the switch cause would leave the cash protection unreliable.
How error code OFF differs from similar codes
OFF is the shutdown stage after the alarm. ALrn on Quantum washers and Alrm on dryers are the earlier alarm messages.

Is oFF a heat or gas problem?
No. It follows door or coin vault switch readings.
Can I bypass the switch to restart?
No. Never bypass a door switch.
Why does it stay off after I latch the vault?
The control may still read a switch wrongly, so the switches and wiring need checking.
