What does Speed Queen error code Ed mean?
The output board on a Quantum topload washer switches the valves, the lid lock and the drive. When it fails one of its own checks, the control shows Ed followed by two characters. The XX stands for a number that tells a technician which check on the output board failed. The board is not operating properly, so valves, the lock and the drive are not under full control, and the washer stops with the code on the display. That is why the whole code matters: Ed alone only says the output board has a problem, while the two characters point to which check. Poor power or loose plugs at the output board, a specific board check shown by the two-character value, a board that has failed internally, and a weak link between the control and the output board are the likely areas. A lid that stays locked is possible when the board is not in command, so wait before reaching in.
Affected models and control systems
This page covers Quantum topload washers in the TLW13C family. CHM1792C washer-extractors report output board trouble as E nr or E id oUtPUt instead.
Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.

Possible causes
Listed in Speed Queen's documentation
- Poor power or loose plugs at the output board
- A specific output board check shown by the two-character value
- An output board that has failed internally
- A weak link between the control and output board
Other likely causes — what usually sits behind error code Ed on this control. A technician confirms which one it is before any part is replaced.
- A harness plug at the output board that has worked partly out from vibration
- A board that was replaced recently with a damaged connector pin
Safe checks before calling for service
- Write down the full code, including the two characters after Ed.
- Give the lid lock time to release before reaching in.
- Leave the cabinet closed.
- When you book service, read us the code exactly as it appears.
How a technician diagnoses error code Ed
- Read the full Ed code, including the two characters, and look up the check it reports.
- Measure the supply and grounds feeding the output board.
- Inspect plugs and the link between the control and output board.
- Reproduce the failing check and see whether it clears after reseating connectors.
- Replace the output board only after the supply and wiring test good.
- The output board switches valves and the drive at line voltage, and opening it live is dangerous.
- The two characters only help if the technician has the manual's check list for that value.
- A dead board and a bad plug look the same from outside, so meter checks decide.
