UniMac Washer-Extractor Error Code EI0E: IR Encryption Error

What does UniMac error code EI0E mean?

The programming settings of a UniMac UW pocket hardmount washer-extractor are protected by a security code, so a stray tool cannot rewrite how the machine washes. When a tool sends data through the infrared window, the control compares the code in that data with the one it holds. If they do not match, the control refuses the transfer and shows EI0E. That protects the machine's settings from the wrong tool. Regular washing is unaffected, and nothing in the wash, drain or spin systems is involved in the message. The manual points to the security code entered on the tool, the pairing between tool and control, the aim during the transfer, and the security setting held in the control. A typing slip in the code, or a tool set up for a different washer, is the ordinary explanation. Guessing codes over and over is not helpful; check the right one and try once more.

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. EI0E belongs to the infrared message group.

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

• EI0E on the display after sending data
• Tool reporting a rejected code
• Normal washing
• Same refusal on every repeat with the same code

Possible causes

Listed in UniMac's documentation

• Security code entered on the tool
• Pairing between tool and control
• Aim during the transfer
• Security setting held in the control

Other likely causes — what usually sits behind error code EI0E on this control. A technician confirms which one it is before any part is replaced.

• A tool still set to the code for another washer in the same laundry
• A security code that was changed on the control and not updated on the tool
• A transfer garbled enough that the code arrives incomplete

Safe checks before calling for service

How a technician diagnoses error code EI0E

1. Read the code and confirm the security code held for this machine in the programming records.
2. Check the tool's stored machine pairing and its code entry.
3. Repeat the transfer with a clean aim to rule out a garbled code.
4. Try a second paired tool.
5. Reset the security setting only following the maker's procedure.
