Water is pouring from water dispenser onto the floor, unable to flow into machine even if drawer is removed. How do I fix this?

If you remove the top cover you will see the soap dispenser unit on the left. It has a large rubber hose connecting it to the drum. If you remove two screws at the front you can free the dispenser for maintenance. You can undo the clips on the various hoses and check that they are clean.

Some people report some dripping from the soap dispenser even when the hose is unblocked. This seems to be a design fault.

The pipe from the soap dispenser to the tub is quite large, it seems as if the water isn't getting out of the dispenser quick enough. Pull the whole dispenser out of the machine. There is a release clip at the back of the cup with the tray fully open. Clean out all soap residue and scum. Sometimes there is also a spot or setting for liquid or powder detergent. Adjust accordingly. Reassemble and try it again.

You may have to remove the washer top (three phillips screws at the back, then push top back about two inches and lift it off) then drill a hole in the top of the plastic dispenser to allow you to use an object like a screwdriver to maneuver the offending part around so it will drop down and allow you to open the dispenser drawer. Use foil tape to seal hole if you don't want to buy a new dispenser. Clean out blue plastic dispenser parts so detergent will siphon out completely. Pushing down on the center tab at the back of the dispenser should allow you to take the dispenser drawer the remainder of the way out. In the future, make sure you do not use over 1 tablespoon of HE soap (and 1 teaspoon of fabric softner) max per load. Even less if you have 2x or more detergent.
