Thank you for your question and I understand your concern.
It will need to drain before it will spin. If you are not hearing the drain pump motor running when it should be draining, it could have a jammed drain pump, a faulty drain pump or a faulty motor control board. A drain pump motor failure can also take out the control board.
If the drain pump is not jammed or blocked, the drain pump motor can be disconnected from under the tub and the motor windings can be tested for resistance with an Ohm meter. It should measure 7 Ohms plus or minus 8%. If it measures approximately 7 Ohms; plus or minus 8% and you have experience and feel safe and confident in measuring the voltage supply to the drain pump, it should measure 120 volts. If you do not measure any voltage, I suspect a faulty motor control board.
I added a couple of images below. One image shows how to access the pump impeller to see if it's jammed. The second image shows how to turn the drain pump on and off. The third image shows where the voltage to the drain pump is connected at the motor control board. The voltage to the drain pump can also be measured as shown in the third image.
NOTE: I do not recommend measuring voltage unless you have experience and feel safe and confident in doing so; otherwise I strongly suggest calling a service technician to diagnose and repair your washer.
I hope this is helpful. If I may be of further assistance as more details become available, please reply to this post.
If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website:
