Fault Code Description Chart

The following chart is a quick reference guide for fault codes.
To read a fault code on an 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
DD605 PCB LCD. This will not be able to be used on DD603 products, or a DD603 test handle used on DD605 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
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.
Lid motors ran but did
not reach stall
current.
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
• The element has failed closed circuit.
