Error Code: E57 Difficulty: Hard
Problem: Motor/inverter module communication error or voltage issue.
How to Fix E57 Error (Step-by-Step)
- Unplug the washer from the wall outlet and turn off the water supply valves to ensure safety. Wait at least 5 minutes for any stored electrical charge to dissipate.
- Remove the top panel of the washer by unscrewing the screws at the back. Then, remove the larger rear access panel to get a clear view of the internal components.
- Locate the motor control board, which is typically found at the bottom of the machine near the motor, and the main control board, usually located at the top front behind the control panel.
- Carefully inspect all the wiring harnesses and connectors going between the main motor, the motor control board, and the main control board. Look for any signs of loose connections, burnt marks, or damaged wires. Reseat any connectors that appear loose.
- If wiring is secure, proceed to replace the motor control board. Take a photo of the wire connections before you begin. Carefully unplug each connector and remove the screws holding the board in place. Install the new board, secure it with the screws, and reconnect the wires exactly as they were.
- If the error persists, the main inverter/control module may be at fault. This is a more complex replacement. Again, take a photo for reference, then carefully disconnect all wire harnesses and remove the old module. Mount the new module and reconnect all wiring harnesses securely.
- Reassemble the washer by securing the rear and top panels. Turn the water supply back on and plug the washer in. Run a short test cycle to confirm the repair.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
What to Check Next on This Bosch Washer
Bosch Washer Error E57: Use the code or symbol as the starting clue, then confirm the actual symptom before ordering parts.
- Unplug the washer before touching wiring, the lock, the pump area, or the control panel.
- Check the door lock, drain filter, inlet supply, and visible harness connections before replacing controls.
- If the code returns during the same part of the cycle, match the repair path to that stage: fill, wash, drain, spin, lock, or control response.
If the issue returns after these checks, match replacement parts to the complete Bosch model number from the appliance tag. The same code can point to different components depending on the exact model and when the failure appears.
