Speed Queen Washer Error Code Eio 32: Door Lock Relay Pin
Eio 32 means the input and output board on a CHM1792C washer-extractor found a problem with the door lock solenoid relay pin. The check on the line that drives the relay did not pass, so the control will not rely on the lock and the cycle stops. Wait for the lock to release, post a sign, and call us.
High: the door lock circuit failed its check, and the machine will not run until it is repaired.

What does Speed Queen error code Eio 32 mean?
The door lock solenoid in a CHM1792C washer-extractor gets its power through a relay, which is simply the switch that connects the solenoid to its supply. The control cannot see the relay directly, so the input and output board checks the line that drives it. If that line does not read as it should, the control cannot be sure the relay will close when the door must stay locked, or open when it may be released. Eio 32 is the result of that failed check. The control will not rely on the lock, so it stops the cycle and the code shows on the display. The manual lists a relay drive output on the board that does not respond, damaged lock solenoid wiring that confuses the relay check, and an unstable supply to the input and output board. Water, balance and load size are not part of this code.

What you may notice
- The cycle stops and Eio 32 stays on the display
- The door lock does not behave as it should
- The machine will not start another cycle
Possible causes
Listed in Speed Queen's documentation
- A relay drive output on the board that does not respond
- Damaged lock solenoid wiring that confuses the relay check
- An unstable supply to the input and output board
Other likely causes — what usually sits behind error code Eio 32 on this control. A technician confirms which one it is before any part is replaced.
- A relay coil output that has aged from many thousands of lock cycles in a busy laundry
- A pinched lock cable at the door frame that shorts under pressure
Safe checks before calling for service
- Read the display and write down the whole code.
- Wait for the lock to let go before touching the door.
- Skip any thought of bypassing a door switch.
- Post a sign and phone us or use the online form for service.
How a technician diagnoses error code Eio 32
- Read the full code and see whether it returns after a power cycle.
- Inspect the lock solenoid wiring for chafing or a short, with power off and locked out.
- Measure the supply to the input and output board.
- Check the relay drive signal against what the control commands.
- Test the solenoid coil resistance.
- Replace the wiring, board or lock only after the test points to it.
- The relay switches the solenoid supply, so testing it means working beside live voltage.
- The door lock is a safety circuit that is never bypassed, even briefly.
- Finding which of the drive output, the relay or the wiring has failed takes a meter and a lockout.
How error code Eio 32 differs from similar codes
Eio 32 is the relay pin check. Eio 30 is the disable pin and Eio 31 is the pulse pin, while Eio 35 is the lock output hardware.

Related Speed Queen washer error codes
What does the relay do?
It switches the solenoid's power. If its drive line fails the check, the control stops rather than trust the lock.
Can I reset Eio 32 and carry on?
You can restart once to see whether it returns, but if the code comes back keep the machine off.
Is it safe to open the door after the stop?
Wait until the lock releases; do not pry or force it.
