  • Page 8: Technical Overview

    TECHNICAL OVERVIEW Electronics The DD601 electronic controller has two separate micro controllers on the main printed circuit board. One is for motor control and output switching and the other is for controlling interface and console functions. The user interface comprises a printed circuit board for front controls and a touch switch panel for internal controls.

  • Page 9: Filling

    The tub extends 510mm out of the cabinet by travelling along two rigidly attached slides on either side of the tub. 3.3.2 Drawer Fronts Prefinished drawer fronts are formed from a prepainted blank of steel. The drawer fronts are attached to the tub by means of formed hooks and two pins which are inserted through either side of the tub.

  • Page 10: Dispensing Detergent

    Dispensing Detergent The dispenser is mounted in the front wall of the wash tub. The detergent dispenser consists of two detergent chambers, one for pre wash and the other for the main wash. The detergent dispenser door is opened manually for detergent loading and then manually closed ready for the detergent to be transported to the wash tub by the inlet water.

  • Page 11: Wash Cycle

    Wash Cycle 3.7.1 The tub is the main cavity where all the wash activity occurs. The tub is a plastic recepticle which has a wash pump and sprayarm at the base. The tub also has guide vanes around its walls which direct falling water from the wash cycle in a clockwise direction around the filter plate.

  • Page 12: Filter Plate

    3.8.4 Overheating Control The heater plate is only activated during the wash cycles. It is not used for drying. The temperature is maintained by the thermistor. The element circuit is continuously monitored by the electronic controller and will switch a fail safe relay if a fault is detected in the heater circuit.

  • Page 13: Drying Cycle

    3.11 Drying Cycle Immediately after water from the final hot rinse has been drained from the tub, the drying system begins operation. The fan draws air through the tub, where it absorbs water from the dishload. The moisture laden air is then mixed with a larger quantity of ambient air (from the kitchen), to minimise the amount of vapour visible when exiting from the drawer front.

  • Page 14: Wiring Cover

    3.14 Wiring Cover The wiring cover protects the customer from the 240V mains supply which passes over the link assembly and under the lockring to the front of the tub. It also serves to protect the motor assembly, drain and fill hoses from damage when opening and closing drawers.

  • Page 15: Diagnostics

    DIAGNOSTICS Setup & Diagnostics The DishDrawer comes with comprehensive fault codes and built in diagnostics, to save the user & service person time and worry, if the dishwasher ever exhibits a fault. Fault Modes The faults are displayed in the LCD as one of 8 F (fatal) faults or one of 3 U (user) faults.

  • Page 16: Diagnostic Modes

    Diagnostic Modes 4.3.1 Temperature Display Mode During a wash cycle, the current water temperature can be displayed on the LCD instead of the time remaining. To enter temperature display mode, start a wash cycle as normal. Initiate a keylock by pushing and holding the Keylock button for 4 seconds.
  • Page 17 4.3.5. Water Pressure Set Up The DishDrawer can be set to either High(Standard) or Low inlet water pressure. The LCD displays the current water pressure setting. If “HP” is displayed then the setting is High Pressure. If “LP” is displayed then the setting is Low Pressure. Low pressure is generally less than 50kPa or equivalent to that supplied by a ceiling tank.
  • Page 18 4.3.9 Clearing Fault Logs To Clear the current Fault press the Keylock button until a beep is sounded. This action moves the Current Fault into the Previous Fault while clearing the Current Fault. To Clear the Previous Fault press Keylock once more until the beep is sounded.
