IPSO Washer Error Code Ed07: No Setup Error

What does IPSO error code Ed07 mean?

Before the motor drive moves the basket, the front-end control must send it a setup packet. That packet tells the drive the limits it must work within. Only after that does the control send commands such as tumble or spin. If a movement command arrives first, the drive has no limits to follow, so it refuses to move the motor and reports a no setup condition, which the control shows as Ed07. Operators see a machine that does not tumble or spin properly after a step starts. The manual's remedy is a power cycle, which makes the control send the packet again from the beginning. A loose link, a power glitch at start-up, or a control and drive that have fallen out of step could cause it. A single occurrence is usually harmless, but a pattern suggests the data link or the drive's memory.

Affected models and control systems

The CHM495R family of washer-extractors, 20 to 100 lb, with the front-end control. Other controller generations use different 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

• Basket does not tumble or spin after a step begins
• Ed07 on the display
• Cycle stalls at the first motor step
• Code appears right after a power flicker

Possible causes

Listed in IPSO's documentation

• The data link between control and drive
• Power glitches at start-up
• The control's command sequence

Other likely causes — what usually sits behind error code Ed07 on this control. A technician confirms which one it is before any part is replaced.

• A brief power dip that interrupted the setup message
• A control or drive replaced recently with mismatched software
• A connector contact on the link that has loosened
• A drive that fails to store its settings

Safe checks before calling for service

How a technician diagnoses error code Ed07

1. Read the code history and see whether Ed07 follows power events.
2. Verify supply steadiness at the machine during start-up.
3. Inspect the control-to-drive link and connectors with power locked out.
4. Check the control and drive versions to confirm they match.
5. Replace the drive or control only after link and supply tests pass.
