Electrolux Washer Extractor Error Code 11: Unbalance Breaker On at Start
Error code 11 means the mechanical imbalance breaker, where fitted, was already active when the wash program started. This is a switch condition and not a load spread unevenly in the drum. A technician should check the imbalance breaker, its edge connection and the cables.
Medium: the program will not start, but the cause is a switch or cable condition and no water is involved.

What does Electrolux Professional error 011 / unb. on at prog. start mean?
Some washer-extractors have a mechanical imbalance breaker, a switch that opens when the drum swings out of true. The CPU board expects that switch to be at rest when a program begins. If it is already active at start, the board shows ERROR 011 / UNB. ON AT PROG. START and does not begin. This is about the switch, not about the linen. Re-spreading the load will not help if the breaker is stuck, shorted or kept active by a mechanical problem. The manual lists a defective imbalance breaker, a mechanical problem that holds it active and a short in the edge connection or cables. The message is seen right after pressing start, before water enters the drum. It does not appear on machines without the breaker.
Affected models and control systems
This applies to the W465H-W4300H, W475S-W4330S and W475N-W4330N washer-extractors, Type W3..., with the Compass Control, where the imbalance breaker is fitted.
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 Electrolux Professional's documentation
- Defective imbalance breaker
- Mechanical problem keeping the breaker active
- Short in edge connection or cables
Other likely causes — what usually sits behind error 011 / unb. on at prog. start on this control. A technician confirms which one it is before any part is replaced.
- Breaker arm bent or resting against its stop after a hard spin
- Moisture or detergent residue bridging the breaker connection
- Chafed breaker cable near the suspension movement
Safe checks before calling for service
- Open the door and check that the drum is empty and nothing is wedged around it.
- Switch the machine off and on, then try starting a program again.
- Do not try to rebalance the load, because the manual says the cause is the breaker status.
- Note that the message appears at program start and before any water, then call us.
How a technician diagnoses error 011 / unb. on at prog. start
- Read the code and confirm it appears right at program start.
- Inspect the imbalance breaker mechanically for binding or a bent arm.
- Measure the breaker switch state with the machine isolated.
- Check the edge connection and cables for a short.
- Replace the breaker or repair the cable only after the test.
- The breaker and its cables connect to the control board and must be checked with covers open and power off.
- A breaker held active by a mechanical problem needs a technician to inspect the suspension and drum.
- Bypassing a breaker lets a badly out-of-balance drum spin, which can damage the machine.
How error 011 / unb. on at prog. start differs from similar codes
Code 11 is the imbalance breaker already active at start; it is a switch condition, not an unevenly spread load.

Will redistributing the load help?
No. The manual describes the switch being active at start, not the load itself.
Does every machine have this breaker?
The manual says where fitted, so some machines will not show this code.
Can I bypass the breaker?
No. It protects the machine from spinning badly out of balance.
