Cycle Count Retrieval
(not available on integrated models)
To display the cycle count on the LCD screen, pause the DishDrawer while running a Continuous Cycle. The two bytes of the cycle count will be displayed alternately, in synchronization with the changing backlight.
The Low byte is displayed when the backlight is Off.
The High byte is displayed when the backlight is On.
To calculate the Total DishDrawer cycle count use the formula below.....
Cycle_Count = (200 x High_byte) + Low_byte.
Eg. Low_byte = 156
High_byte = 2
Cycle_count = (200 x 2) + 156 = 556
Temperature & Voltage Display Mode (not available on integrated models)
During a wash cycle, the current water temperature or the power supply rail voltage of the controller can be displayed on the LCD instead of the time remaining. To enter temperature/voltage display mode, start a wash cycle as normal. Initiate a keylock by pushing and holding the Keylock button for 4 seconds.
Once in keylock mode push and hold Start/Pause for 8 seconds to enter temperature display mode. The display now alternates between a C symbol and the water temperature. Pressing the Start/Pause again changes the display to alternate between an E symbol and the power supply rail voltage of the controller.
To cancel temperature/voltage display mode, press the Power button.

Fault Code Description Chart
The following chart is a quick reference guide on fault codes. To read a fault code off an integrated model, or prefinished products after MEM741743, 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.

A fatal fault will usually require the assistance of a qualified service
person, while a U1 user fault 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. In the Integrated models, an LCD is not available, and the
presence of a fault is indicated by a Red center LED, with the fault number indicated
on the touch switch panel with Red LED’s.
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.
The last two faults are logged into EE memory.
The other U (user) faults have been removed. The old U2 fault, which was the tub forced open during a cycle, has been removed completely. Instead if the tub is forced open the product simply pauses as if someone had pressed the start/pause button. The old U3 fault, which indicated a failure to drain i.e. water left in the tub, will not show up a fault and the DishDrawer will continue through the cycle.
