Fault Code Description Chart
The following chart is a quick reference guide on fault codes. To read a fault
code off an integrated or flat door model, refer to the LED Display column on
the chart below. 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
or flat door models using a cut down handle and a DD605 PCB LCD. This will
not be able to be used on DD603 products, nor can a DD603 test handle be
used on DD605 products.
