Motor runs when door is open- water does not come in- seems stuck

depending on the brand and mdl the unit may be equipped with an overflow safety. If ther is water under the dishwasher in the floor pan then the sensors will trick the dishwasher into thinking it is leaking. Check under the kick plate . if it is moist then take a hair dryer and dry it up up until there is no moisture at all. This should cancel out the pump command and you can start over .
