What is the Sanitize cycle used for?
This cycle is intended for sturdy white or colorfast items that benefit from stronger stain or hygienic treatment.
It may use warmer water, longer washing or a specialized additive phase depending on the model and selected options.
Choose another cycle for: Dark colors, delicate fabrics and anything that cannot tolerate the selected temperature or additive.
What this means for your load
Higher-temperature treatment for heat-safe items when available. Check the appliance display for its current estimate.
Why the time may change: Water heating, soil level, additives and extra rinses can add significant time.
