UniMac Washer Error Code EI0F: Infra-Red Disabled
EI0F on a UniMac UW pocket hardmount washer-extractor means the control has its infra-red port turned off, so it cannot take data from an external tool. Nothing is broken, and normal washing is not affected. Enable infra-red on the control if you know how, or re-aim the tool and try again.
Low: a data link message only; the unit keeps running.
What does UniMac error code EI0F mean?
EI0F is the message that infra-red is disabled on UniMac UW pocket hardmount washer-extractors such as the UWL035K12. The control has a setting that turns its infra-red port on or off. When a tool tries to send data while the port is off, the control answers with EI0F instead of accepting the transfer. Nothing is broken. The port is simply switched off until someone enables it by hand, and the tool needs to be pointed at the window again after that. Normal washing is not affected, because this concerns only the data window. The manual lists an infra-red setting switched off on the control, a tool pointed at the window while the port is off, a dirty window hiding the real problem, and a control setting changed by someone earlier.
Affected models and control systems

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
- EI0F when a tool is pointed at the window
- The tool gets no response
- Wash cycles are normal
- Transfers work only after someone changes a setting
Possible causes
Listed in UniMac's documentation
- Infra-red setting switched off on the control
- Tool pointed at the window while the port is off
- Dirty window hiding the real problem
- Control setting changed by someone earlier
Other likely causes — what usually sits behind error code EI0F on this control. A technician confirms which one it is before any part is replaced.
- The port switched off on purpose to keep others from changing settings
- A control reset or program reload that returned the setting to off
- A setting changed by accident while someone browsed the control menus
Safe checks before calling for service
- Enable infra-red manually on the control if you know how, or re-aim the tool and try again.
- Make sure the window is clean.
- Hold the tool steady during the transfer.
- If you cannot enable it or EI0F stays, call us.
- Ask coworkers whether anyone changed control settings recently.
How a technician diagnoses error code EI0F
- Confirm the infra-red setting on the control and read its current state.
- Enable the port using the machine's own procedure.
- Repeat the transfer from close range with the tool steady.
- Check whether a security setting or a reload turned it off.
- Test the receiver only if the port is enabled and still silent.
- The setting lives in the control's menus, and changing the wrong option can affect how the machine runs.
- If the port was turned off on purpose, someone responsible should decide whether to turn it on.
- If the port is on and still fails, testing means opening the control near 208-240 V circuits.
How error code EI0F differs from similar codes
EI0F means the port is off. EI0E means the port works but the security code did not match.
