On low speed, the pump motor makes a clicing noise but sounds normal on high speed. Checked for debris but all seems clear. This just started recently. I can send video of high and low speed if it helps.
The most common cause of your clicking sound would be a bad run capacitor.
If it’s not the capacitor, check out the following thread for more information. https://www.inyopools.com/forum/thread/hayward-superpump-dual-speed-wont-work-on-low-speed/
