soap dsipenser would not open, and no lights on the main display panel.

Removed front panel for access to the back of the soap dispenser. Visually inspected the diespenser, and it looked okay. Ordered new electronic control board and bi-metal fuse from PartsSelect to address the no-power situation. The parts arrived in 2 to 3 days. Once the dishwasher's front panel is again removed, the control board and fuse are right there for easy access. The control board snaps out easily. All attaching wires unplug easily. All the wires are plugged into the new control board. It's easy, and they cannot be mixed up.Snap the control board back into place.The fuse can be unpluged and easily tested with a continuity tester or multimeter.If it's bad,the lead wires are cut, and the new fuse is easily spliced in. Reattached the front panel, and everything worked perfectly.
