Samsung gave us very little guidance but your website explained that we needed a new ECS module. We ordered a new module and replaced it. We were able to pull the old module by removing the panel on the right side of the dishwasher. Replacing the ECS took care of the problem. Be sure to put a towel under the module before you remove it. This will soak up any water that drains out and keeps it from triggering the "leak" sensor. If you reconnect the power to the dishwasher and it immediately starts trying to pump out and drain the dishwasher, water is in contact with the leak sensor. At that point, you will have to try to reach under things and towel dry or wait several days for it to evaporate on its own.
