Hi delores! Your washer uses both hot and cold water dynamically, in a system called Auto Temperature Control. Also, different parts of the cycle will use either hot or cold water, or both. For instance, the Warm cycle uses only cold water until the final rinse. It is also important to note that certain temperature settings are only available on certain cycles. Page 39 of the user manual (https://bit.ly/3CAMjPz) has a helpful guide for this. ^Jecca
