RE: Washing Machine Spin Cycle Not Working
I had the same problem. The machine will do the washing cycle. At the start of the spin cycle it would start turning with a lot of clicking sounds and then would stop spinning. The water pump would continue working without problem. The motor tries to start again in about three minutes, however, repeats the same behavior.
I have a reasonable mechanical and electrical knowledge. I was sure that the overload protection switch of the motor was tripping. I opened up my machine, a GE super capacity top loading machine. Took off the belt and turned the transmission pulley. It turned easily in both directions (washing and spinning). Hence, the transmission was good. Next, I checked any water accumulation in the spin tub. If the water is not drained properly before the spin cycle, it would overload the motor. There was no water clogged in the spin tub. Finally, I dismantled the electric motor. There was a clutch assembly underneath the motor pulley. I dismantled it and found the clutch very dirty with some grease that had turned sticky. I cleaned the assembly thoroughly with alcohol and assembled back the machine. The machine is running perfectly after that.
Conclusion: The clutch assembly was mis-functioning.
Reason: When the spin cycle starts, the spin tub is very heavy and cannot achieve the full speed quickly. On the other hand, electric motors must get to their running speed fairly quickly or else overheating of motor would happen. A proper functioning clutch allows the motor to run at their optimal speed while transferring enough torque to the spin tub to slowly speed up the tub to its fullest. In my case, the clutch was sticky, thus overloading the motor which would trip as it overheats. (03/01/2009)
