Smart Fill System

 

 

 

The drain system consists of the following components:

Auxiliary drain pump (includes motor and one- way check valve)

Drain tube

Check valve (in line with drain tube)

Drain hose

The inlet cover prevents large particles from entering the sump. Water entering the drain pump is not filtered by the fine filter (metal) or by the sump filter (plastic). The drain pump is mounted on the sump and contains a one-way check valve. The drain pump is controlled by the control module and can be activated using Service Mode.

The drain pump utilizes a 120V AC motor. The motor should read approximately 30 .

IMPORTANT: The drain system of this dishwasher requires either a high drain loop or an air gap. Installations without either a high drain loop or an air gap will not perform properly.

High Drain Loop

The Smart Fill system consists of a new silent fill hose design and electronicly controlled cavitation sensing (adaptive fill).

The new fill hose design uses a rigid plastic tube with rubber over mold at both ends. This smaller diameter reduces water flow rate and fill noise. The required water line pressure is still 20 to 120 psi.

Fill Hose

The cavitation sensing controls the amount of water for each fill. The dishwasher fills for 57 seconds, then the pump motor starts. The load on the motor changes as water enters and exits the sump. The electronic control monitors this change as motor current fluctuation and continues to fill the tub until the fluctuations are stable, assuring the sump is full.

Note: The maximum amount of time the electronic control will energize the water valve is 95 seconds.

During a normal wash cycle, the water level in the tub will cover the sump screen or be just to the rear edge of the heater bracket. The dishwasher will fill with approximately 1.2 gal. of water.

Water Level

Depending on the wash cycle selection, a complete wash cycle will use between approximately 2.5 gal. (Rinse Only) to 10.9 gal. (Cookware - heavy soil level).
