UniMac Washer Error Code EI0A: Infra-Red Framing Error
EI0A on a UniMac UW pocket hardmount washer-extractor is an infra-red framing error: the washer could not read the shape of the incoming data, so the message was not accepted. Normal washing continues. Re-aim the tool, clear anything in the way and move a little closer.
Low: a data link message only; the unit keeps running.
What does UniMac error code EI0A mean?
EI0A is an infra-red framing error on UniMac UW pocket hardmount washer-extractors such as the UWL035K12. Data over the infra-red link is sent in frames, each with a recognizable start and end. The control looks for that shape in the signal. When it cannot find it, the message cannot be separated into usable pieces, and the control rejects the whole message and shows EI0A. It usually means the signal was partly blocked or garbled while it was being sent, for instance by a hand, a sleeve or a tilted tool. Only the data link is involved, and normal washing continues without trouble. The manual points to the aim of the tool and anything between it and the window, the distance from the window, the tool battery condition, and the control receiver if it repeats.
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
- EI0A appears as soon as the tool starts sending
- Tool shows no response from the washer
- Normal cycles are unaffected
- Moving closer helps
Possible causes
Listed in UniMac's documentation
- Aim of the tool and anything between it and the window
- Distance from the window
- Tool battery condition
- Control receiver if it repeats
Other likely causes — what usually sits behind error code EI0A on this control. A technician confirms which one it is before any part is replaced.
- A cart or laundry bin parked between the operator and the control
- The tool held at a steep angle above or beside the window
- A cracked or yellowed window cover blurring the beam
Safe checks before calling for service
- Re-aim the tool at the window and make sure nothing is in the way.
- Move the tool a little closer and hold it steady.
- Try the transfer once more.
- If EI0A returns on every try, call us.
- Note the distance and angle at which you tried.
How a technician diagnoses error code EI0A
- Confirm the tool's battery and its emitter are working.
- Check the window cover for cracks, film or discoloration.
- Run the transfer straight on at close range.
- Swap in a second tool to compare.
- Replace the receiver only if every tool fails at close range.
- The receiver is behind the control panel next to line-voltage wiring.
- A scratched window cover and a weak receiver look the same and need a test to separate.
- Fixing the control hardware means working inside the cabinet with the power locked out.
How error code EI0A differs from similar codes
EI0A is unreadable message shape. EI09 is a data check mismatch, and EI01 is a send that never completes.

What is a framing error?
The washer could not tell where the message began and ended, so it could not read it.
Does it affect washing?
No. Only the data link is involved.
Can I fix it myself?
Often yes, by re-aiming, clearing the path and moving closer.
