Once the fault has been cleared for an F3, F8 or F9 fault, the power needs to be disconnected and reconnected to reset the isolation relay before the product can be used again.

4.7Fault 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.
