COMPONENTS
4.1
Control and power modules
Ascenta dishwashers have two control modules, a control module
(with display, lights & buttons) in the fascia (control) panel and a
power module in the base on the right side. The power module
controls the BLDC drain pump and heat pump.
The wire harness connected to the control module can either be a
separate harness or the 1-piece dishwasher harness, depending
on when the dishwasher was built. The wiring is the same, with
the only difference being whether the dishwasher has three
harnesses or one harness.
4.2
Door latch
The door latch is mounted on top of the tank and doesn’t contain
a microswitch. It uses a Hall-effect sensor in the door to sense
the door latch magnet to determine if the door is open or closed.
The Hall-effect sensor is held by two T-10 Torx screws. The door
latch is held by one T-20 Torx screw and two tank tabs.
