UniMac Washer-Extractor Error Code EI0C: IR Time-Out Exceeded

What does UniMac error code EI0C mean?

EI0C is the stronger relative of the plain infrared time-out on a UniMac UW pocket hardmount washer-extractor. The control has a limit on how long a whole transfer may stay open. When that overall limit is passed, it closes the session and posts EI0C. It points to a link that stalled partway through. The cycles and mechanical systems of the washer are not involved, so batches can still be processed. A tool that moved before the transfer finished, or a tool whose power ran low mid-transfer, are the common reasons. A smudged window over the infrared receiver can slow the exchange until it runs out of time, and a control receiver that stalls on repeat attempts is the last possibility. The manual lists those four. Starting over from the beginning, with a steady tool and fresh power, normally finishes within the allowed time.

Affected models and control systems

This applies to the PHM1263R family of UniMac UW pocket hardmount washer-extractors, models UWL, UWN and UWU 035 to 125, such as the UWL035K12. EI0C is an infrared time-out message on this control.

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

• EI0C on the display after a long transfer
• Tool counting up and then ending the session
• Washer cycles unaffected
• A shorter transfer that succeeds

Possible causes

Listed in UniMac's documentation

• A tool that moved before the transfer finished
• A tool whose power ran low mid-transfer
• A smudged window over the infrared receiver
• A control receiver that stalls on repeat attempts

Other likely causes — what usually sits behind error code EI0C on this control. A technician confirms which one it is before any part is replaced.

• A large settings file that takes longer to send than the control allows
• A tool that pauses to save or process data between blocks
• A cabinet vibration from a running machine nearby that shifts the tool during a long transfer

Safe checks before calling for service

How a technician diagnoses error code EI0C

1. Read the code and ask how long the transfer ran before it ended.
2. Check the tool's power and try a smaller transfer.
3. Clean the window and test the link at close range with a steady mount for the tool.
4. Compare behavior with a second tool.
5. Test the receiver only if long and short transfers both stall.
