It sound that the problem is cause the water level switch. 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 tube first from any obstruction, 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 !

Sounds like you've diagnosed the solution on your own.. Most of the inlet valves are spring loaded so that if power is removed or disabled.. it defaults to a closed state and doesn't allow water int the wash basin. To open, they need to be energized by the control system so you may have one of two issues.. a faulty inlet valve that doesn't spring closed when it is not energized or a controller that is comanding that valve to open ( less likely of the two) For a quick test.. make sure the DW is dry inside and open the door. wait and watch for water to enter the basin.. If it does begin to fill up.. your inlet valve could be the root of your problem.. It is also possible that you are back-siphoning waste water in from the drain system. If the water looks dirty then that is more than likely the problem so you may have a clogged pump, kinked drain hose or your drain system itself is not draining as fast as the DW pump forces the water out.
You should routinely clean the pump filter so that the pump can remove all the wash water without having to draw it thru food debris caught in the filter.. Hope someof these ideas will help you solve your problem..

if your dishwasher is cleaning poorly, check these:
Most cleaning problems are caused by the dishwasher not getting enough wash water, so the water-inlet valve is often to blame. This valve is usually at the bottom left or right of the dishwasher, behind the lower access panel. It's the device with the main water line from the house, a rubber tube to the dishwasher, and two wires attached to it.
When a water-inlet valve is defective, you may hear the sound that's usually referred to as "water hammer." If the water-inlet valve is defective, you need to completely replace it.
Dishwasher Water Inlet Valve Replacement
Be sure to read and understand any instructions that come with the new water inlet valve.
Step 1. Disconnect the dishwasher from its power source.
Note: Dishwashers are usually wired directly to the home’s electrical system. To disconnect the power, switch off the circuit breaker or remove the fuse for the electrical circuit the dishwasher is attached to. Try to turn the unit on after disconnecting the power to be sure you were successful.
CAUTION: If you’re not sure you’ve shut off the power properly, DO NOT CONTINUE. Call a qualified appliance repair technician to complete the repair.
Step 2. Turn off the water supply to the dishwasher. This is usually underneath the kitchen sink or in the basement or crawlspace near the location of the dishwasher. Pliers may be helpful here.
Note: If there are no shut-off valves, you must shut the water off at the main water supply valve for your home.
Step 3. Remove the lower panel(s) of the dishwasher. These are usually held by 2 to 4 screws at the upper and lower corners of the panel(s).
The inlet valve is usually near the front of the dishwasher. Attached to the valve you’ll see: 2 or 4 wires, the water supply line from the house and the water feed line that goes to the dishwasher.
Step 4. Remove the household water supply line from the valve. The line is usually secured with a brass compression nut. The water supply line is usually copper or braided stainless steel.
CAUTION: Water supply line may be hot.
Step 5. Remove the fitting from the valve the water supply line was attached to. This fitting may be very difficult to remove. It may help to put the valve into a vice in order to remove the fitting. If you cannot remove it, replace it. The fitting is not an appliance part but a plumbing part that is available at most hardware stores.
Step 6. Remove the screws holding the valve to the dishwasher frame.
Step 7. Label the wires to the valve so you’ll be sure to reattach them correctly.
Step 8. Remove the wires from the valve.
Step 9. Remove the clamp on the black rubber water discharge tube and pull the tube off of the valve.
Step 10. Reinstall the old fitting (or a replacement fitting if necessary) onto the new valve the water supply line was attached to. Use Teflon tape or pipe joint compound as a thread sealant. Make this fitting tight to prevent leaks. Make sure that the fitting points in the same direction as the old one so that the water supply line will meet up with it properly.
Step 11. Install the new valve in the reverse order of the removal instructions.
Note: The water supply line is under high pressure. Be sure to tighten the fittings properly.
Step 12. Turn on the water to the machine, and check for and correct any leaks.
Step 13. Reinstall the access panel(s). Restore the power to the dishwasher and test.
Note: You may have to let the dishwasher run a few minutes before it reaches the next water fill cycle.
Internal filters Every dishwasher has some type of filter to keep large food particles and foreign objects away from the pump assembly:
Drain valve Some dishwashers have a valve (or gate) that should open only during draining. If debris lodges in the valve, it can't close properly, so water drains out during the wash cycle. Most dishwashers drain into the garbage disposer. If yours does that, listen for water flowing into the disposer during the wash cycle. If you can hear it then, the drain valve may be clogged.
Spray arms There's a spray arm at the bottom of your dishwasher--it may have a tall spray tube mounted to the center of it. There may also be a spray arm located directly beneath the upper rack of dishes and/or above the upper rack.
If debris is blocking the holes in the spray arms where the water comes out, it could cause cleaning problems. Regularly inspect each of the spray arms and clean out the holes as necessary.
Water temperature To get the best cleaning results, the water entering your dishwasher needs to be hot enough. Try running the hot water in your kitchen sink for about 30 seconds before starting the dishwasher, to pre-heat it. Also, if your dishwasher lets you select a higher wash or rinse temperature, try that to see if it helps.
To check the temperature of the hot water that comes from your kitchen faucet use a waterproof thermometer. If the water isn't 120 degrees Fahrenheit, your dishwasher may have trouble getting your dishes clean. You could increase the temperature of the hot water to the whole house--and therefore the dishwasher--by adjusting the hot water heater thermostat.
Warning! To lessen the risk of scalding, don't set the hot water heater temperature higher than 120 degrees Fahrenheit.
Detergent cup Dishwashers don't perform their best if detergent is introduced only at the beginning of a cycle, so add detergent to both parts of the cup.

I would check your fill valve screen, where your water line connects to
the dishwasher, lots of times i will see that screen clogged,
especially on customers homes that have wells.
There is no way to change the fill time on these.
There is also the potential problem with the float sticking if it is gunked up it will not allow water in...see that it moves up and down freely and you should here a clicking noise.....If it is not one of these there could be a problem...with the timer...I am providing a link that will help walk you through this problem in a more technical...manner...if you are not comfortable performing these tests...i suggest you forego it and let a tech handle it....
this is one continuous link.....you can scroll down until you see the won't issue.
I hope this helps ..good luck, have a good day& please rate my effort......The Fang

SOURCE: dishwasher wont fill with water
Make sure you get water to the dishwasher. Check to see if the water shut-off valve (located under the sink) is open. If you get water to the dishwasher, but there is still no water inside during the fill cycle, the problem might be with a faulty water valve (located at the bottom of the dishwasher, behind the kick panel, on either side), in which case replace the water valve.
