Found unit off. Tried to fill, found shutting off too soon. As soon as probe gets hot, fill shuts off. Spoke with Jim at Jackson and there is a water level board with sensitivity control that needs to be installed. Will order and return. 2/20/17 found unit off. Removed low water level sensor and made sure it was clean. Reinstalled sensor and made sure tight seal and no contact with machine body. Filled and unit stopped at proper level. Ran unit, drained, refilled 5 times with no issues. Unit working properly at this time. ** No charge labor for 2/20 per Service Manager **No Charge travel and miles per Service Manager
