Speed Queen Washer Error Code E:08: Inoperative Control

What does Speed Queen error code E:08 mean?

E:08 belongs to the same entry in the manual as E:07, and both describe an electronic control that is not working. This is not a wand message, so aiming the Micro-wand IIIe at it will not help. The control runs on a steady supply and a working program. When either is lost, it cannot carry out the commands that run the washer, and it stays on the code until power is cycled (display text: E:08). The manual's possibilities read a little differently here: a control board that cannot run its program, a weak supply reaching the control, or a plug on the control that has worked loose. These are all conditions that leave the washer with no one at the controls. Timer-type toploads like this are an older line, but they are still working in laundries, and we repair them. After a power cycle the display may recover for a moment, yet a code that returns means the cause is still present. Keep customers away from the washer meanwhile.

Affected models and control systems

Older Speed Queen timer-type topload washers with the EDC electronic control (Micro-wand IIIe programming). Newer Quantum washers use a different code set.

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

• E:08 on the display
• The washer does not start or stops mid-cycle
• The code stays until power is cycled

Possible causes

Listed in Speed Queen's documentation

• Control board cannot run its program
• Weak supply reaching the electronic control
• Plug on the control worked loose

Other likely causes — what usually sits behind error code E:08 on this control. A technician confirms which one it is before any part is replaced.

• A shared circuit in the laundry sagging when several machines start at once
• Moisture that reached the control housing through the top of the cabinet

Safe checks before calling for service

How a technician diagnoses error code E:08

1. Read the code and see whether it returns after power is cycled.
2. Check supply voltage at the washer under load.
3. Inspect the control housing for moisture or loose plugs with power off.
4. Check grounding and the neutral connection that feeds the control.
5. Replace the control board only when the supply and plugs test normal.

How error code E:08 differs from similar codes

E:07 carries the same manual description with its own list of possible causes.
