Sorry to say but plain distilled water does not do anything. It will not clean your records, it doesn't matter how many cycles you do. It won't remove grease or fingerprints. You need to use 1 1/2 ounces of isopropyl alcohol (70%) per tank and a surfactant to properly clean records when using an ultrasonic machine.
As for the WEWU rotisserie. The records are too close together. The cavitation wave will not be able to move all the way up the record. You should have at least 1 inch between the records, 1 1/2 inches would be ideal. I would recommend just cleaning 2 or 3 records at a time with that system.
This is the surfactant that I use. You only need 1 ounce per tank. This is a case where more in NOT better.
