I have used the plastic nubby balls for years in my Splendide 2100xc combo, only during the drying cycle.
I don't do laundry if we are not at home. We always turn our water off when leaving to avoid any potential disaster, so, it's not a problem to turn the dry cycle off.
At the end of " wash", fluff the clothes, put the dryer balls in start the dry cycle (10).
Easy peasy. Don't overthink a simple thing.
