Washing Machine Motor Fault

Recommended Posts

I am assuming all washing machine motors are pretty much the same so I was hoping somebody could advise me.
My washing machine tries to spin but cuts out after a second or two. It is not the control board as the motor does try to turn but gives up after an initial burst of energy.

I have taken the motor off and tested the 8 pin connector with a multimeter and got the following results.
I assume pins 1, 2 & 3 are the motor. There is continuity across all three terminals.
Pins 4 and 5 are brushes. Full continuity except when I spin the motor from stationary I get a split second of discontinuity spinning one way but not the other.

Pins 6 and 7 are taco coil no continuity except when I spin the motor from stationary I get a split second of continuity spinning one way but not the other.
Pin 8 is earth and none of the terminals show continuity with it. All parts of the motor casing show continuity with it.
I cannot see any damage to the taco coil but there is what seems to be a magnet or carbon bush around the end of the armature that is broken. This piece is definitely supposed to be moulded/shaped around the end of the armature and sits tightly inside the taco coil.

What do you think? I think that because the moulding on the end of the armature is broken and I do not get continuity over the taco coil pins then both the motor and taco coil will need replacing.
Thanks in advance for your input.

If the magnet on the end of the armature is broken or the small tacho coil has fallen off the motor then the washing machine can't read the speed of the motor through the tacho coil. This would normally cause an uncontrolled spin or the motor to not run at all depending on design. The machine may abort if it cannot control motor speed because of a broken tacho coil.

Read this article for more details on the motor tacho coil and problems associated with the motor spinning and then aborting.
