Two things could make no water come in. The water valve being bad, or the float being stck. If you need me, you can reach me at ApplianceEducator.com Tom

Here is a link to your unit with a schematic
Maytag MDB7130AWS

If I understand your post the dishwasher never fills with water. Even on rinse only cycle. Is this correct?
Do you have a volt/ohm meter.
If not go buy one, digital multimeters are inexpensive these days. You do not need a fancy one. It is a good idea to get one with leads that are a couple feet long.

Measure voltage at the start of a cycle when it should be filling with water.
Measure from L1 (power side of water valve) to far far side of float switch (looks like this goes to pin 5 on your control board). If you have 115 volts here then measure across the water inlet valve. If you have 115 volts here then either the valve is shot, the inlet screen is clogged or you have a problem with your water supply.

If you have 0 volts on all the above then use the resistance setting of the meter to be sure you do not have a broken wire going to these components from either line (L1) or the control board (looks like pin 5). Best to disconnect power to the unit when doing this. When measuring resistance always disconnect one side of what ever you are measuring. This ensures that you do not measure a parallel path.

Dmatuszko, with out a whole lot of confusing diatribe, let me see if I can help you. When you open the door of your dishwasher, on the front left hand corner is a float cup. That is the float switch assembly. Some times there is a cover over it. If there is take the 1/4 inch screw out, and remove the cover. What I want you to do is lift the float up and down. If you get close to it, when you bring the float cup up, and then let it down slowly, you should here a click. That is the switch making contact. If you here it, it is most likely OK. In thirty years in the business, running about 8 to 10 service calls a day, I might have replaced 5 float switches. Since someone probably gave you bad advice to replace the control board, that would leave the water valve. Replace it. If you had gone out and bought a ohm meter, like Mr. Deman asked you to. What you might find is if you checked ohms on the water valve solonoid, because you read ohms don't mean its good. Again, I would replace the water valve if you hear the click of the float switch. If you need me I can be reached at ApplianceEducator.com Tom
