Huebsch QN Washer-Extractor Error Code E d 24: I2T Overcurrent
E d 24 is a fatal I2T hardware over current error: the drive watches both how much current flows and for how long, and this time the combination crossed a protective line. Cut power to clear the message, then once the lock releases check with power off that the drum is not wedged. Run a lighter load next time, and call us if the code is back.
High: the drive stops the motor on a fatal error and the machine will not complete cycles until the cause is found.
What does Huebsch error code E d 24 mean?
Where the shunt error in E d 23 is a sudden spike, the I2T protection is about duration. The drive multiplies current by time, and a motor that draws a moderate overload for a long time can trip it just as a short spike would. E d 24 is the report that the combination crossed the drive's protective line, so it stopped the motor. Operators see the machine halt suddenly under load. The manual's steps are to check that the rotor is not locked up, check the motor phase windings, and power down to clear it. A binding drum or a motor that is drawing too much current are likely. The manual's causes are a drum or rotor that binds and pulls heavy current, a motor winding that draws too much current for too long, a drive current measuring circuit that has failed, and a heavy or lopsided load that keeps the motor straining. The last cause is one an operator can influence directly by balancing the load. The third needs a technician to prove, since the drive can be wrong about the current.
Affected models and control systems
E d 24 is listed for CHM1792C-family Huebsch QN washer-extractors (20 to 100 lb) with the front-end control. Other controller generations use different drive 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
- Machine halts suddenly under load
- E d 24 on the display
- Often follows a heavy or lopsided load
- Motor may feel hot after the stop
Possible causes
Listed in Huebsch's documentation
- Drum or rotor binding and pulling heavy current
- Motor winding drawing too much current for too long
- Drive current measuring circuit failed
- Heavy or lopsided load keeping the motor straining
Other likely causes — what usually sits behind error code E d 24 on this control. A technician confirms which one it is before any part is replaced.
- Worn bearing causing growing drag over several weeks
- Winding partly shorted so it draws more current at a given load
- Frequent overload cycles that wear the motor before the code appears
Safe checks before calling for service
- Cut power to the machine, which clears the message.
- Once the lock releases, check that the drum is not wedged, with power off.
- Run a lighter load next time, so the motor has an easier start.
- Call us to schedule service if the code is back, and tell us the load size when it happened.
How a technician diagnoses error code E d 24
- Read the code and ask about load size and balance before the stop.
- With the machine locked out, check the drum and rotor for drag.
- Measure the motor's phase windings for balance and insulation.
- Compare the drive's current reading with a clamp meter during a spin to test the measuring circuit.
- Replace the motor, bearing or drive board according to the results.
- Comparing the drive's current reading with a meter is live work around 208 to 240 V.
- A rotor that is locked up may be held by a damaged bearing that needs the basket removed.
- Telling a failed measuring circuit from a real overcurrent takes test equipment an owner does not have.
How error code E d 24 differs from similar codes
E d 24 is current held too high for too long. E d 23 is a sudden shunt overcurrent, and E d 22 is motor temperature.

Related Huebsch washer error codes
What does I2T mean for me?
It is the drive's measure of current over time. A moderate overload for long enough can trip it.
Will a lighter load fix it?
It helps if the load was the cause. If the code returns on a light load, the motor or drive needs service.
Is the code the same as E d 23?
No. It is a similar protection, but based on duration.
