Maytag dishwasher soap will not rinse out

Likely the float valve is deformed and no longer seated on its micro switch. Remove the bottom kick plate and look for a flimsy white spike seated on a micro switch but bent out of its proper position. The float looks like an upside down cup located near the front left corner of the inside of the dishwasher. The shaft of the float is a skinny 1/8 inch flexible piece of plastic. It deforms routinely under the light weight of the cup and the heat accumulating below the dishwasher. You can reseat the shaft on the micro switch for a temporary fix. For a permanent fix try re-enforcing the shaft with aluminum tape and a long sewing needle. Keep the retrofit very light weight to avoid over weighting the micro switch. A jammed water level sensor float can cause either no water (your situation) or water overflowing onto the floor. Usually the overflow water flows around the shaft of the float and pours our from underneath the kick plate
