Glad you found the fuse on the pump motor. I looked 3 times before I found mine. Not in the best location; one handed retrieve and replacing the 15 amp fuse one handed is a bear.
You could pull the control panel out and jumper across the switch terminals to see if the motor is activated. HWH has their service manuals online. this link HWH Service Manuals
will take you to a page with all their manuals. Might try downloading your slide manual as it may take HWH awhile to get back to you.
