The wash motor is probably mot moving the water. You will need to verify 120vav coming from the two light blue wires on the board. if you have 120vac when the motor is supposed to be running you need a motor, if not hten you need a board.
if you hear a humming noise when the washer is supposed to be spinning something is physically blocking the motor from turning or the motor is bad. Depending on the age and model it could be anything from a motor coupler to shifter solenoid to a transmission. If you have a model number that would help to diagnose.
If it sounds like the unit is running through the cycle but the motor is not running you probably need the motor. There is an off chance you it can be the board however with these Whirlpools the motor is more likely. I do agree that is is strange it runs the motor in one hour cycle and not normal, that doesn’t normally happen. There are t15 screws on the inside of the door if you remove those the front panel should come loose but there are tabs on the hinge that will keep it from falling. There are two plastic covers over the wires coming out of the board, once you remove those you will be able to access the wires. There are two light blue wires nest to the largest connector that power the motor. You can test from the backside of this connector with needle probes or take this connector out and test the prongs on the board. you will need to let the dishwasher fill and be in the part of the cycle when the motor should be running. If there is 120v there you need the motor, if not you need the board. You can...
When you push the start button do any lights flash? If the clean light flashes seven times you have a heater error and the board is locked out. You will have to diagnose whether the problem is the board, heater, tco ot thermister. If a light above a button flashes quickly it means that button is stuck and the console with UI needs to be replaced. If there is no response whatsoever from the unit when the start button is pressed chances are the console with the UI needs to be replaced. You can use the model number to find the part on any number of sites. If you replace the console I would strongly recommend replacing the board thermal fuse as well, it tends to go out a few days after touching the wires in the control area.
the camera cable socket if definitely fixable I have done this many times. It is not for the faint of heart and you will definitely need a scope and fine tipped soldering iron to do so. I would not attempt to take the glass off the front of a unibody Macbook Pro unless I was prepared to buy a replacement. I broke the first three that I tried to remove myself...Replacement glass runs around $50. I have never heard of a faulty camera causing high fan speeds. I have seen some funny problems when a USB circuit is shorted, although it usually just causes the computer not to post. Can you post a high res picture of the connector that is broken?
