Warm the cups by rinsing them with hot water. You can use the machine hot water function.
Position a container under the steam/hot water spout (as close as possible to avoid splashes).
Turn the steam/hot water dial to the 'I' position.
Danger of scalding!
Never leave the machine unattended when hot water is being released. The tube of the steam/hot water spout heats up when in use.
To shut off the flow of hot water manually, turn the steam/hot water dial to the '0' position.
