4.6 Fault Codes
There are 10 F (fatal) faults, which are displayed in the LCD along with the
symbol of a spanner (not on integrated or flat door models). A fatal fault will
usually require the assistance of a qualified service person.
In addition, there are 4 U (user) faults.
U1 indicates the machine had failed to prime within a certain length of time
usually because the tap has not been turned on. For this reason, at the same
time a U1 comes up in the display we also show the symbol of a tap.
U2 indicates restricted lid travel. The customer can usually rectify a U1 or U2
fault.
A U3 fault is not displayed to the customer, but is recorded in the fault history
and displayed in Smart Tool. It is logged if the motor senses prime in less
than 20 seconds because water was left in the tub from a previous fill, or
because it has filled too quickly. The product will drain and refill up to 5 times
before logging the fault and continuing on with the cycle.
On a double drawer model, a U4 fault indicates an F fault with the other tub
that has disabled the power supply.
In the Integrated and flat door models, an LCD is not available, and the
presence of a fault is indicated by a red centre (start/pause) LED, with the
fault number indicated by the red LEDs on the touch switch panel.
Once a fault is repaired, it can be cleared by pressing the POWER button. If
the fault is still present, then it will not clear.
A fatal or user fault is accompanied by a continuous pulsating beep, which
can be turned off by pressing either the POWER, START/PAUSE, or KEY
LOCK button. This also stops the drain pump running for an F1 fault.
The last two faults are logged into EE memory.
If a tub is forced open, the product simply pauses as if someone had pressed
the start/pause button.
Except for U4, F1, F3, F8 and F9 faults, the other tub can still be used on a
double drawer model.

599464
18
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.
4.7 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.
