Fault Code Description Chart

The following chart is a quick reference guide for fault codes.
integrated model, refer to the LED Display column on the chart. The LED that has activated on the
secondary display indicates which fault code has occurred. To make diagnostics easier, a test
handle can be made for use on integrated products using a cut down handle and a DD60/DD24
PCB LCD. This will not be able to be used on DD603 products, or a DD603 test handle used on
DD605/DD60/DD24 products.

Fault
The bottom controller
flood sensor detector
has been activated for
more than six
seconds.
The controller has not
sensed the motor
rotating.
The water
temperature has been
sensed as greater
O O
than 85 C (185 F).
No temperature
increase has been
sensed for about 4
hours while the
element is on.
Lid motor current too
high during start.
Possible Causes
• Lid not closing.
• Overfilling.
• Foaming.
• Not draining.
• Lid seal damaged.
• Dispenser or water softener or their seals
leaking.
• Damaged water inlet or drain hoses.
• Leaking heater plate or motor seals, or drain
o-ring seals.
• Yoke jammed or broken.
• Inlet hose to inlet valve connection loose.
• Inlet valve body leak.
• Heater plate damage (chipped enamel).
• Dry F1 – PCB mains filter, harness or
connectors, electronic controller.
• Foreign object has jammed the rotor.
• The rotor has failed.
• Hall sensor connector or wiring fault at hall
sensor or controller.
• The hall sensor has failed.
• Motor stator winding or connection open
circuit.
• The electronic controller has failed.
• PCB mains filter has failed.
• The incoming water is greater than 85
O
(185 F).
• The element has failed closed circuit.
• The temperature sensor on the heater plate
has failed.
• The electronic controller has failed.
• The element is not connected.
• The element has failed open circuit.
• The temperature sensor has failed.
• The electronic controller has failed.
• Lid jammed up or down.
• The electronic controller has failed.
