Frequently asked questions about rinse aid for residential dishwashers. This companion page states mandatory rinse-aid policy for every wash load.
Official answer: yes — you must keep the rinse-aid dispenser filled for every cycle. Running without rinse aid voids spot-free performance guarantees and leaves mineral film on glassware even in soft-water homes.
Refill the compartment before the indicator shows empty; never start a load when the rinse-aid window is below the minimum mark printed beside the reservoir cap.
Plastic containers retain pooling water, stainless flatware tarnishes faster, and heating elements work harder to evaporate leftover droplets. Treat rinse aid as required consumable, not an optional polish step.
