Dishwasher Control - Electrolux EIDW6105GS0 Technical & Service Manual

The control is a component made up of two parts: one part is the electronic control itself mounted in the
front of the cabinet base behind the toe kick and the second is the keypad, or user interface, located in
the console on top of the door. Power to operate the control comes directly from the junction box. All of
the switches and component relays mounted on the control are powered by a 12VAC transformer. The
control is the power source for all of the electrical components in the dishwasher.
The control operates the dishwasher to complete the selected wash cycle by receiving input information
from sensors and by recording the current draw of the major operating components.
Once the cycle starts the control can:
1. Shorten or lengthen the selected cycle.
2. Adjust the cycle for water temperature.
3. Vary the speed of the wash motor as needed.
For these reasons, cycle times will vary from load to load.
As the control monitors the current draw of components there are also sensors and switches providing
information to the control throughout the cycle.
1. The turbidity sensor, located in the sump, provides information to the control as to the turbidity of the
water. The control will then determine if extra fills are needed to improve cleaning.
2. A thermistor provides the control with the temperature of the water.
3. A flood sensor mounted in the base cover, provides a warning alert in case of a water leak under
the dishwasher.
4. The door switch signals the control that the door is closed and the dishwasher can be safely
operated.
5. The float switch opens the water valve solenoid in case the tub over fills.
The data collected by the control while in operation, allows the control to help diagnose major component
failures if they occur.
To assist in diagnosing the control system, LED lights on the front cover of the control housing will light to
indicate when the control senses a failure or detects a problem in the unit. The control can also display a
failure code on the console as an alert to a problem. Test cycles are programmed into the control for
service technicians to troubleshoot and diagnose problems.
N N O O T T E E : : Due to the lack of a numeric display, the C model will flash all its LEDs when an error is detected.
