Huebsch CHM495R Washer-Extractor Error Code Ed06: Drive Overheating
Ed06 on a Huebsch CHM495R washer-extractor is a thermal error caused by high IPM temperature: the power module in the motor drive got too hot, so the drive stopped the motor. Power the machine down and let it cool completely, and keep the space around it clear. Space out heavy loads until we have checked the drive, and ask us to clean and check it if the code repeats.
Medium: the drive stops to protect itself, and cooling usually restores operation.
What does Huebsch error code Ed06 mean?
The power module in the motor drive, called the IPM, makes heat whenever the motor works hard, and the drive's heat sink carries that heat away. If the module temperature gets too high, the drive stops the motor to protect itself and displays "Ed06". Operators see the machine quit after a string of heavy loads or in a hot room. The manual's steps are to power down and verify convection around the drive heat sink. Lint buildup, blocked airflow and a hot laundry room are the main reasons the heat cannot escape. The manual lists poor airflow past the drive heat sink, lint and dust caked onto the drive, a hot, poorly ventilated room around the machine, and a drive temperature sensing circuit reading too high. In a warm summer a laundry room with little ventilation can push a drive past its limit on the busiest afternoons.
Affected models and control systems
This page applies to CHM495R-family washer-extractors, 20 to 100 lb, with the front-end control and motor drive.
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 quits after several heavy loads in a row
- "Ed06" on the display
- Cabinet and room feel hot
Possible causes
Listed in Huebsch's documentation
- Poor airflow past the drive heat sink
- Lint and dust caked onto the drive
- Hot, poorly ventilated room around the machine
- Drive temperature sensing circuit reading too high
Other likely causes — what usually sits behind error code Ed06 on this control. A technician confirms which one it is before any part is replaced.
- Boxes or carts stored tight against the cabinet that block the vents
- A dryer exhaust leak that fills the room with warm lint-laden air
Safe checks before calling for service
- Power the machine down and let it cool completely.
- Keep the space around the machine clear and the room as cool as you can.
- Space out heavy loads until we have checked the drive.
- Ask us to clean and check the drive if the code repeats, and note the time of day it happens.
How a technician diagnoses error code Ed06
- Read the code and ask about room temperature and recent load schedule.
- With power locked off, inspect the drive heat sink for lint and dust.
- Check airflow paths and ventilation around the cabinet.
- Verify the drive temperature reading against actual heat sink temperature.
- Clean the heat sink, then replace the drive only if it still overheats.
- Opening the drive compartment exposes capacitors that hold a charge after power is off.
- Cleaning lint from a heat sink without damaging the drive board takes the right tools and technique.
- A drive temperature circuit reading falsely high has to be separated from true overheating with measurements.
How error code Ed06 differs from similar codes
Ed06 is overheating in the drive's power module. E tp on the Quantum topload is a different case, a motor thermal protector.

Related Huebsch washer error codes
Can I restart after it cools?
Yes, once cooled, but heavy loads back to back may bring it back.
Is the room temperature really that important?
Yes, a hot room and blocked airflow are the manual's main reasons the heat cannot escape.
Does Ed06 mean the motor is hot?
No. It is the drive's power module that is hot.
