Technical Information
When the water tank is installed, and contains at least 30-33 ounces of water; the Water Level Switch is activated and its contacts close.
If the water quantity drops below the minimum quantity, the water level switch is no longer activated and the contacts open.
After the switch opens, the water passing through the water pump is registered via the flowmeter and recorded by the electronic unit as up to 27 ounces of water is still available.
After the 27 ounces is calculated as being used, the display shows “Fill water tank”. To prevent the water pump from running dry, about 3 – 7 ounces of water remains in the tank.
If the appliance is placed into the service mode the top line of the display shows the switches that have been activated. A “7” is displayed when the water tank is installed and filled with water. Refer to section 6 – Service Mode for further information.
