Bosch Nexxt 500 Series Washer (WFMC5301UC) fills with water but doesn't Wash/Agitate or Spin (Belt is fine - no Error/Fault Code listed).

I cleaned the Pump Filter (after manually draining the Water) and the Pump Impeller turns freely (has resistance at the 12, 3, 6 & 9 o'clock position's). Therefore, I have a multimeter and need instruction's on how to check the Drive Motor, Motor Control Unit & Centrol Control Unit for AC/DC Voltage and/or Continuty/Ohm's.

Hi Robin,

Thank you for submitting a question to Manage My Life.

You mentioned that the washer was not showing an error, but you did not mention whether or not you had run the test sequence. The first thing I recommend is checking for error codes. If the motor is not running, there should be an error code stored. This washer has a test routine you can run that will help in the diagnosis of any problems the control detects. If the control detects a problem it will identify it with an error code. I am including this information in a set of images below.

The motor on this washer is a 3 phase variable frequency. The technical information from Bosch does not tell us exactly how to, where to, or when to, check for a particular voltage. It does however demonstrate ohming the windings (see image below), that is where you should start (after the test program). I also gave you a wiring diagram. This is a poor diagram, but it is the only one I have. If you decide to check voltage to the motor, I recommend that you do it during the motor test.

Working with live electrical current can be very hazardous and possibly deadly. Do not attempt these measurements without the proper tools and safeguards. If you are not already sure you can perform these checks safely and competently, refer this work to a qualified professional.



Please perform the diagnostic tests detailed here and report back with your findings. Be sure to record any failures and when they occur along with any error codes that are displayed.

If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website:
