Why aren the sprayer arms turning?
Make sure that nothing is blocking the sprayer arms. Some models of dishwashers have an alternating sprayer arm washing system. What this does is cycle the washing action between the lower sprayer arm and the middle sprayer arm. The cycle begins with the lower arm spraying first, then switching over to the middle sprayer arm, and back again through-out the washing cycle. The sprayer arms will pause as they switch over from one to the other, making it sound like the sprayer arms aren’t turning. If you’re sure that the arms are not turning at all, open the dishwasher and verify that nothing is blocking the sprayer arm rotation, and that there is water in the bottom of the sump covering the filter area.
