Whirlpool washer agitates, but won't spin with full load
I have a Whirlpool Ultimate Care II Quiet Wash I washing machine, Model #LSB6400LW1. The washer agitates fine, and but will not spin with a medium load WITHOUT my reaching in to the washer and helping it get started (by twisting the inner basket like a roulette wheel).
With a full load (it is a Super Capacity washer), the unit will not spin at all, even by helping it to get started.
I have a couple hypotheses, but would rather first hear from a professional repair person or someone else who has had this same issue on what could be causing the "spoin with help, but no spin with full load" syndrome. Thanks!
