Customer Questions and Answers for Washer Drain Pump by Bosch

Hello Erik, The 03 error code is a long drain. Disconnect the drain hoses and check for blockages. If no blockage "time" the drain interval. If it's more than 6 minutes it's the pump 00144489. Also make sure you're using the correct type of soap so the ball check valve on the bottom of the outer drum isn't getting fouled with excessive suds. If the Carbon Brushes in the motor need replacing: Take the back panel off of the washer. Unscrew the (green) ground wire from the motor and take off the belt from the lower wheel and the big wheel. Undo the big bolt on the (red) arm holding the motor. Undo the bolt from the backside of the motor to the right of the of number 3 and the motor will come right out now. Pullout the wire connectors from the motor so you are now completely able to spin the motor. Pull out the old carbon brushes and notice the angle of the end so when you put in the new one on that side it matches. It was tricky to get the spring to stay while I set the new clip but I used a flat head screwdriver to push on it. Put it all back the same way you took it off.
