Step-by-Step DIY Fix Guide

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.
