Sudsing
I had issues with my Point Voyager when using rinse aid. It was bad enough where I couldn’t use it because it released a small amount during the main wash and caused crazy sudsing issues regardless of detergent. Cascade action Pacs did foam up bad, but didn’t hinder performance as long as no rinse aid was in the dispenser.
However, the Bosch did struggle a bit with sudsing with Cascade Action Pacs. Finish Quantum was good until reformulated.
The power clean KitchenAid and new KA just kick ass regardless of what is used. But we did have hard water with the PC.
