Re: hood does not pop up when depressing the push button
The filter elements are mostly likely not correctly in place so the latch is not tripping the micro-switch. Using a flash light this was clear by looking down into the front edge of the vent unit. I could see the element edge and the latch of the filter element. It wasn't latched tight. I used a paint scraper (two). Gently i nserted it while also using a flash light to see. I was able to lever and jiggle the filter element back into place and latch it. This activates the control. Then the unit would raise. I double checked the filter latches to be sure they were tightly closed.

Hi, The door latch pulls the door tightly closed to prevent water leakage around the door. It is also designed to prevent operation while the door is open. The door latch works in concert with the door switch to ensure that the door is tightly closed and latched.The door switch is a separate part from the door latch and is found inside the cabinet. The switch is off when the door is open. Depressing the switch closes the circuit and enables dishwasher operation. Closing the door does not depress the switch all the way. Only when the door is closed and latched, does the door fully depress the switch. If the door latch is not properly aligned it may not pull the door tightly closed and the door switch will not be fully depressed. Unless the switch is fully depressed the dishwasher will not operate.It is a simple matter to determine whether the door latch is the problem. Simply open the door, close the latch and select a cycle and depress the switch. Note that if the test is successful, with the door open, the dishwasher will operate and water may spray out. Make sure to first remove all tools from inside the dishwasher. Do not reach inside the dishwasher during the test. Now, inspect the cabinet where the door makes contact with it and locate the door switch. It may have a protruding button or spike or more likely it is a hole with a piece of metal or plastic inside it. You must fully depress that switch. If the switch is recessed, then use a non-conductive object, such as a wooden pencil, to depress the switch. Thank you !!
By removing the decorative cover plate you somewhat expose the units inner workings. Carefully, insert a small sharp object into the unit at the point in which the micro-switch(es) are exposed. The micro-switch(es) will appear as small little plastic tabs that are poking out. While simultaneously depressing the power button, insert the sharp object into the micro-switch(es) closing the circuit. The down draft will raise enough to the point in which you can re-seat or install the filter thus making it operational.
check your bottom limit switch - i'm guessing its bad. the unit doesn't stop operating til it trips a (working) limit switch, if the switch is bad it'll cyle right past it and go back up until it hits the top limit switch (again).
