How to test a washing machine motor

This video is on how to wire a washing machine motor AC direct. This will help you diagnose whether your printed PCB is the fault or the program, by knowing your motor is working correctly you will be able to eliminate this from the process of why your washing machine has no wash cycle or spin.

    Great info, but would you have any info on my washer motor at all. It is a 7 wire motor for an Indesit. Name on the motor is Indesco and one of the brush wires disappears into the winding’s.
    Many thanks,
    Martin.

    • hi 🙂 i have such a stupid question :
      first the video really help me so much 😀
      #2 how can i test the motor weather it rotate clock wise or anti at low speed ?
      and when it moves clock or anti does that mean that the motor uses the brush to move at low speed whatever the direction?! or the brushes just for high speed only ??

    Excellent video – however assuming that the motor is working correctly how do you check if the tachometer is functioning? I’m going to assume that the tachometer is just a coil of wire clamped around a spinning magnet, so that when the motor is rotating a current is generated which would be fed to the machine’s processor PCB?.

    The above being correct, is it a simple as checking the tacho for continuity, if yes what resistance should you expect to read?

      Hi Chris
      Since I am having similar issue that you describe (machine washes OK but does not spin any more) did you find a way to test spin function to see if missing spin issue is caused by motor?

      U will need a device that can read waves such as an oscilloscope when the tachometer wires are connectet to the device it should read a sino cidal or squre wave when the motor is runing or been turned.

    useful video, and entertaining due to the typo on the last page – we help you diagnose your faults 🙂

    Thanks thats useful

    I have a 17 yr old Indesit WDG1095W and no response from motor, PCB control module looks clean and all good

    Have voltage at the various pins on the motor, Checked brushes and comunator all is now good and clean, But motor wont turn

    Motor is Indesco 940N2i.01

    Wiring config is: 1: Tacho / 2: Tacho / 3: / 4: Red (Into motor loom) / 5: / 6: Brown (into motor loom)
    7: Black into 1 brush / 8: Black (into motor loom) Other lead from motor loom go’s to other brush.

    Going to wire a rig up to see how I get on, But thinking the windings may have OC

    • Hi Chris yes it sends pulses to PCB to know what rpm the motor is doing, The PCB increases or decreases the voltage as more speed or less is required depending on where it is in the wash cycle or rinse and spin cycle. i hope this helps

          Hi
          I found solution to spinning problem. In my case brushes were OK but motor would not take speed. So motor was the issue not the PCB/timer.
          Seems to be well known issue that when induction motors like this are getting worn they may not spin at higher speeds.
          It needed a helping hand when checking it in external test setup (like the one described by Paul here). So I found a refurbished motor, which then solved the issue.

    Hi, could you please tell me the name of the part which you are pointing on the 7th picture starting from top left, its life a circle with some yellow wires coming out on the left side, thank you, I have been looking for it for a long time.

    • this is a motor tacho: it has a coil and also a piece attached to the Armature shaft and it counts the rotations, this then sends the information to the printed circuit board which is then able to adjust the speed of the motor to the required level of the cycle.
