Speed Queen Washer Error Code EI0C: Infra-Red Time-Out Exceeded

What does Speed Queen error code EI0C mean?

A programming or audit exchange has a time limit set by the control. Once the conversation starts, the control expects it to finish within that limit; if it does not, the control ends the session and shows EI0C. This differs from a simple no-reply code, because here the two sides were talking and the exchange stalled partway. The slowdown can come from the physical link or from the device. The manual lists an external device that drifted off aim during the transfer, a phone or tablet that dropped to sleep mid-exchange, a smudged control window slowing the infra-red link, and a file so large it outlasts the allowed time. The display shows the code after the attempt. It tells us about the data link only, and it does not say anything about fill, drain, door or spin on the machine, so laundry in the drum is not affected by it.

Affected models and control systems

Quantum frontload (FLW1535C family) and Quantum topload (TLW13C family) washers with the infra-red programming 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 shows after a transfer that began and then stalled
• A long file transfer ends with the code more often than a short one
• The washer is otherwise normal

Possible causes

Listed in Speed Queen's documentation

• An external device that drifted off aim during the transfer
• A phone or tablet that dropped to sleep mid-exchange
• A smudged control window slowing the infra-red link
• A file so large it outlasts the allowed time

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 tablet set to dim and lock after 30 seconds, interrupting a long audit pull
• A hand held out at arm's length that tires and drifts during a slow transfer

Safe checks before calling for service

How a technician diagnoses error code EI0C

1. Read the code and ask how large the file was and how long the transfer ran.
2. Set the external device to stay awake and brace it at a fixed spot.
3. Clean the control window.
4. Try splitting the exchange into a shorter transfer, such as fewer options at once.
5. Test with a second known-good device.
6. Replace the control only after known-good devices stall the same way.

How error code EI0C differs from similar codes

EI02 is a reply that never came. EI0C is an exchange that began and then outran its time limit.
