Step-by-Step DIY Fix Guide
- SAFETY: Unplug the machine from the wall.
- Reset by unplugging for 30 seconds, then restoring power.
- If E80 returns immediately, call Bosch Customer Support at 1-800-944-2904.
If the warning comes back after restart
- If airflow still seems weak after the basic checks, the fan path or a deeper obstruction becomes more likely.
- If the warning returns immediately after a clean restart, the sensor or wiring path becomes more likely than a one-time glitch.
- Any recurrence after a 30-second power reset — E80 always requires professional repair
What This Error Means
E80 on your Bosch washing machine means: There is a fault in the drive circuit that controls the drum motor. This is an electronics or motor failure. The machine detects this condition via its sensors and stops the current cycle to prevent further damage. The error will remain until the underlying cause is resolved.
The most frequent cause is failed motor control board (mcb). Work through the causes listed below in order — the first cause is the most likely and the most straightforward to check.
Bosch's official guidance classifies E80 as a technician-only fault. The internal components involved require specialist diagnostic equipment. Do not attempt to open the machine casing — contact Bosch Customer Support at 1-800-944-2904.
The machine will not continue the selected program until the fault is resolved. Work through the troubleshooting steps below before calling a technician.
What users usually notice before this code
Bosch washing-machine warnings like this often appear after a fill problem, a drain slowdown, a badly balanced load, or a startup sequence that did not settle cleanly.
Common misdiagnoses
- Assuming the display code proves one exact failed part before the safe first checks are done.
- Treating a sensor-related warning as a guaranteed board failure before checking the simpler model-family causes first.
- Restarting the appliance repeatedly instead of confirming whether the same fault returns after one clean recovery attempt.
Most Likely Cause by Symptom
The Bosch washing machine may stop, pause, or refuse to complete the cycle normally.
Likely cause: Failed motor control board (MCB)
Check first: SAFETY: Unplug the machine from the wall.
The warning may return immediately because the appliance is detecting an internal fault.
Likely cause: Motor winding failure
Check first: Reset by unplugging for 30 seconds, then restoring power.
Common Causes
- Failed motor control board (MCB)
- Motor winding failure
- Wiring fault between the control board and motor
- Power surge damaging motor electronics
What Not to Do
- Do not attempt to open the machine casing to inspect motor components
- Do not run further cycles
