Check that the hose connection is secure and that there aren’t any kinks or blockage in the hose. The hose should always slope downward not go vertical or in an upward direction. If the hose is clean and water flows out freely, check the placement of the unit.

The unit not being level could be another factor as to why it’s collecting water in the bucket and not out of the drain hose. Make sure that the unit is level. If there is a slight slope to the floor, adjust the unit so that the hose is closest to the drain. In units that were stored for the winter, for an extended period of time or in a highly dusty area, there may be grime build up in the main water outlet that connects to the drain accessories. Use a pipe cleaner to help clear the buildup by inserting the pipe cleaner in the main water outlet.
