Whirlpool dishwasher does not fill up with enough water?

[TomS]

I have a whirlpool DU1055XTSS2 dishwasher that does not seem to fill up with enough water.

How full should it be to start with and if it's not getting enough water would the problem be with the float thing or the water valve?

The water level should be just below the heating element.
The float is just a safety shut off as the dishwasher fills on time, so if the timer sticks the float will kill the power to the water inlet valve and stop of flow of water.

If the water level is to low then replace the water inlet valve, part # W10158387
