Wascomat Washer Error Code 11: Imbalance Breaker On at Start
Code 11 means the mechanical imbalance breaker, if the machine has one, was already active when the wash program started. It describes the breaker switch state, not the weight of the load. Switch the machine off and on once, and call us if the code returns.
Medium: the machine will not start a program, though the cause is limited to one switch circuit.
What does Wascomat error 011 / unb. on at prog. start mean?
Some washer-extractors carry a mechanical imbalance breaker, a switch that trips when the drum shakes too hard during spin. The Compass control looks at that switch when a wash program begins. At that moment the drum has not turned yet, so the breaker should be at rest. If it is already active, the control stops the start and shows ERROR 011 / UNB. ON AT PROG. START. This is why the code is not about an unevenly distributed load. A lopsided load can only trip the breaker once the drum is spinning, and this check happens before that. The manual points to three places: the breaker itself, a mechanical problem that keeps it permanently pushed in, and a short in the edge connection or cables to the switch.
Affected models and control systems
Wascomat washer-extractors W465H-W4300H, W475S-W4330S and W475N-W4330N with the Compass Control, where a mechanical 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.
What you may notice
- ERROR 011 / UNB. ON AT PROG. START appears right after pressing start
- The washer refuses to begin a cycle with an empty or lightly loaded drum
- The code appears even after you redistribute the laundry
- The machine started normally before and now never gets past the first moment
Possible causes
Listed in Wascomat's documentation
- Defective imbalance breaker
- Mechanical problem keeping the imbalance breaker always 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.
- A breaker arm bent or jammed after a hard spin trip so it no longer returns to rest
- Lint or moisture in the switch area that holds the contacts closed
Safe checks before calling for service
- Open the door and check that the drum is empty or evenly loaded and nothing is wedged between drum and cabinet.
- Switch the machine off at the disconnect, wait a minute, and switch it on.
- Start a short program and watch whether the code appears immediately.
- Do not remove covers to reach the breaker. Note whether the code comes at once or after a spin, and call us.
How a technician diagnoses error 011 / unb. on at prog. start
- Read the code and history to confirm it occurs at program start.
- Inspect the imbalance breaker for a stuck arm, bent linkage or debris that keeps it active.
- Check the drum suspension and spin mechanics for anything that presses on the breaker.
- Test the breaker switch contacts with a meter at rest.
- Check the edge connection and cables for a short to the switch.
- Replace the breaker or cable only after it fails the test.
- The breaker sits on the suspended drum assembly, and reaching it means opening panels around moving parts.
- Switch and cable tests are done at connections near mains-powered control parts.
- A mechanical cause may require adjusting the drum suspension, which needs the right tools and procedure.
How error 011 / unb. on at prog. start differs from similar codes
Some earlier descriptions blame an uneven load for this code, but the manual ties it to the breaker already being active at program start.

Related Wascomat washer error codes
Is code 11 caused by an unbalanced load?
Not according to the manual. It describes the breaker switch already being active when the program starts, which happens before the drum turns.
Can I run the washer without the breaker working?
No. The breaker protects the machine from violent spin shaking, and we do not bypass it.
What if only some machines in my laundry show it?
Then it points to the breaker or its wiring on that machine rather than a general cause.
