Bosch Maxx Classic Series Fault Codes:

E1 - Heating Error:
Bosch Washing Machine Error E1 indicates that there is a problem with heating of water.

E2 - Motor Error:
Bosch Washing Machine Error E2 indicates that there is a problem with the main wash motor. This error is mostly caused by worn out motor brushes so check them first, broken wires leading to the motor, damaged motor or problem with the main control board.

E3 - Door Lock:
Bosch Washing Machine Error E3 means that the machine has not registered that the door has been shut. Check to make sure that the door has been shut properly. If the door is shut properly but the error is still appearing then there could be other 2 possible causes. Next step is to check the plug on the door lock, if that is plugged in firmly then that means your door lock is faulty and needs changing.

E4 - Unexpected Heating:
Bosch Washing Machine Error E4 indicates that heating is taking place at a stage of the program where it should not.

E5 - Water Inlet Error:
Bosch Washing Machine Error E5 indicates that the machine did not fill up with water.

E6 - Draining Error:
Bosch Washing Machine Error E6 indicates that the machine was not able to drain the water. Check for blockages in the filter and hoses. Drain pump might be faulty.

E7 - NTC Error:
Bosch Washing Machine Error E7 indicates open NTC circuit or faulty NTC sensor.

E8 - Ever filling Error:
Bosch Washing Machine Error E8 indicates that the machine has been filled up with too much water.

E9 - Aquastop triggered:
Bosch Washing Machine Error E9 indicates that the water leak sensor has detected a water leak in the base of the machine.

E11 - Power Frequency Error:
Bosch Washing Machine Error E11 indicates that there is not enough power been supplied to the machine to operate.
