Try resetting the unit by shutting off the circuit breaker first for 1 minute then try the reset button. If nothing happens, then i would recommend having someone take a look at it.

i would assume be n/o.

if have VOM put on OHMS setting. touch ur leads together listen for tone. once verified it works. put on the terminals on switch. and manully switch it, to see if makes or breaks the contact

Make sure that the top shelf slides back fully into position. If the flow nozzle does not fully engage onto the water supply jet at the rear of the shelf this prevents the door from closing fully. Sometimes this can be caused by the gasket wearing and preventing engagement this rubber ring is easily replaced and can be fitted by a novice

flame sensor is dirty or faulty

check with whoever you order the latch from, usually parts are individual for electrical parts and never assume that the screw or washer will come with new one, save every piece.

possible faulty pressure switch or a faulty drain pump

sounds like you have a leak in the base, tip the unit over on the side to see if water pours out if so you need to check what base item is leaking.

There are two ways that dishwashers generally fill. One is a float inside the tub, the second is a tube which fills with water, loops and goes to a pressure switch below the machine. That switch is usually about 1.5 inches in diameter, two wires and a small hose going to it. The float witch is found below the float in the motor area. With the float, sometimes they jam with too much old detergent or food goo. Clean out. Both can have the switch weld closed. Change the switch in either case. Since the unit is not filling with the power off, I'm going to guess the water solenoid is okay.

It sound that the problem is cause the water level switch (stuck in the "full" water position). The switch level is usually a diaphragm device with a small clear tube attached between the switch and the bottom of the washer's outer tub. I am not familiar with this specific machine, but if you will open the rear panel you will find it easily. Clear first any obstruction in the tube,In case it doesn't help, disconnect the wires from the unit (you should disconnect first machine's power cable !!!!!) and measure with a multi-meter on its tugs for continuity and disconnection while you are inhale and blow to its tube. In case it doesn't react, you should replace it. Good luck !
