My Kenmore Elite Catalyst Washer with digital display was not spinning. I replaced the coupler, the old one was worn. The washer did spin however it made a whinning noise. I ran several loads and now it will not spin again. Any suggestions on what the problem may be? Thanks.

The model number of my Kenmore Elite Catalyst is 110 20072 991. The lid switch does click. Thanks
