DRAIN CYCLE

The self-priming centrifugal drain pump oper- ates when the motor is rotating in a counter- clockwise direction. A non-return flap valve on the outlet pipe prevents soiled water from re- turning to the tub.

FILTER PLATE

The drain filter can be emptied with the dish rack in place by removing the cutlery basket and opening the plastic section of the dish rack.

The filter plate is removable for cleaning by removing the dish rack and spray arm and unlocking the lock ring nut counterclockwise.

DRYING CYCLE

The fan moves air through the tub to draw water from the dish load. The moisture-laden air is then mixed with a large quantity of ambi- ent air to minimize the amount of vapor visible exiting from the drawer front.

The fan runs continuously during the drying cycle and will restart if the tub is opened and closed again. After the drying cycle is com- plete, the fan continues to run for 30 minutes, but will not restart if the tub is opened.

LID SYSTEM

The lid is a single piece of injection-molded polymer plastic with an integral static seal. Each side of the lid is clipped into a yoke, which is attached to a worm drive gearbox assembly containing a small brush-type 24V DC motor.

At the beginning of each wash cycle, both motors are powered up for approximately 10 seconds to pull the lid down onto the tub. The lid remains down for the duration of the cycle and is only lifted when the dishwasher beeps to signal the end of the cycle, or if the customer pauses it to gain access to the tub.

If power to the dishwasher fails while the lid is down, the tub can be forced open manually. It is very difficult to close the tub again without lifting the lid. The lid can be wound up manually with the tub fully removed.

FLOOD SENSOR

A flood sensor, located at the edge of the electronic control board in the dishwasher lower compartment, will sense the presence of mois- ture. In the event that moisture is detected, the sensor will signal the electronic control, which in turn, will de-energize the fill valves, and start both drain pumps.
