UniMac Washer Error Code EI0C: Infra-Red Time-Out Exceeded
EI0C on a UniMac UW pocket hardmount washer-extractor means the washer waited longer than it allows for the external tool to finish an infra-red transfer and gave up. Cycles and mechanical systems are not involved. Re-aim the tool, start the transfer again from the beginning and keep it still.
Low: a data link message only; the unit keeps running.
What does UniMac error code EI0C mean?
EI0C means the infra-red time-out was exceeded on UniMac UW pocket hardmount washer-extractors such as the UWL035K12. Where EI02 reports a short wait that ran out, EI0C is the stronger form: the washer waited longer than it allows for the external device to finish and then abandoned the transfer. That points to a link that stalled partway through, not one that never opened. The control keeps a limit on how long it will hold an open session, so that a stuck tool does not tie up the port. Once the limit is reached, the session is closed and the message appears. The cycles and mechanical systems of the washer are not involved. The manual lists a tool that shook during the transfer, a tool running low on power, a dirty control window slowing the exchange, and a control receiver that stalls again and again.
Affected models and control systems
Listed for the PHM1263R family of UniMac UW pocket hardmount washer-extractors (UWL/UWN/UWU 035-125), such as the UWL035K12, front-end control with infra-red window.
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 after a long pause in a transfer
- The tool shows a transfer that never reaches done
- Wash functions unaffected
- Transfer succeeds when restarted from the beginning
Possible causes
Listed in UniMac's documentation
- Tool that shook during the transfer
- Tool running low on power
- Dirty control window slowing the exchange
- Control receiver that stalls again and again
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 long program transfer started with a tool that was nearly out of charge
- The tool set down on a shelf with the beam slightly off the window
- Condensation film on the window after a hot wash
Safe checks before calling for service
- Re-aim the tool and start the transfer again from the beginning.
- Keep the tool still until the message says it is done.
- Make sure the tool has power.
- If EI0C appears again, call us.
- Note how long the tool ran before the code.
How a technician diagnoses error code EI0C
- Check the tool's battery and its state before a long transfer.
- Wipe the window and test from close range with the tool braced.
- Time how long the session runs before EI0C appears.
- Repeat with a second tool to separate a tool stall from a receiver stall.
- Replace the receiver only after both tools stall.
- Checking the receiver means opening the control, where 208-240 V circuits sit nearby.
- A stalled transfer can leave a partly written program, which has to be verified against the machine's own data.
- A tool stall and a receiver stall look alike without a known-good second tool.
How error code EI0C differs from similar codes
EI0C is the long form of the time-out. EI02 is the plain time-out, which fires sooner.

Is EI0C worse than EI02?
It is a longer wait before giving up, but it means the same thing: the link stalled.
Do I lose my program?
Not if the transfer did not finish; verify the settings after a clean pass.
Does it affect laundry?
No. Cycles run normally.
