Does not fill with water! runs OK if I put water in. Could it be the float?

Answer Frank, Yes, the float 8268895 could be stuck in an up (full) position. It could also be the flaot switch 8268909 on the underside of the tub , but it's most likely a faulty fill valve 8531669. You need to remove the lower access panel and kickplate and check the switch and valve wiring. If you carefully lift and lower the float from inside the tub, you should be able to hear the switch activate and deactivate, that's an even easier and faster test. .
Float Part # AP439OO17. Is there an O Ring or any type of seal on the stem of the Float?

Answer Hello Frank. No, there is no o-ring used on the float 99002363. You will need to check and see if the water is filling to much and causing the unit to over flow out of the float chamber. If so, replace the water valve or the float switch. If the switch is testing good, then the valve is bad. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter.
