Critical Errors

Critical errors will turn a cycle off and show a display alerting the consumer of a fault which will not
allow the dishwasher to function or cause an undesirable condition.
No Water Detected

will display the following:
• Models with SSD (Seven Segment Display) Screens: H20 will be displayed on the SSD screen.
• Models without SSD Screens: Wash Temp LED will blink continuously.
Water may be turned off. The consumer is directed to verify the water supply line is connected properly,
the supply line valve is turned on, and then restart the cycle. If this fails, the consumer is directed to
call for service.

and the user interface will display the following:

will run and the User Interface (UI) will display the following:
