It's keep the water inside what do I have to do ??

Sounds like the output fitting has melted inside and clogged up the output pipe. These couplings are one way valves to keep water from draining backwards when not in use to keep from burning elements. They are plastic inside. I would turn off water and replace those after a visual inspect if needed.

Keep the water draining hose at lower surface than the washing machine. also check for any blockage in the water draining vent and water draining hose.

My water dispensor INSIDE the door froze up.
I payed a repair guy $75 to use MY BLOWDRYER to "thaw" the frozen water line INSIDE the freezer door (below the water dispenser).

He said anytime the frozen food extends over the freezer shelf and touches the freezer door for a long enough period of time, the water line inside the door FREEZES!!

PREVENTION: "Keep some airspace between the door and frozen food."

Water inside the door is NORMAL. What needs to happen is to OPEN the drains at the base of the door. Water enters around the glass and ABSOLUTELY cannot be stopped, so, alternatively, each and every door on each and every car is designed to accept water inside the door. You may notice a plastic sheet just inside of the door panel.....This keeps the water off of the (damageable) door panel, and directs the water to the bottom of the door.
Normal condition.

The unit needs to be tilled toword the outside. If it is level it will dip inside. There should be very little water inside.

The water comes from condensation inside the gas tank. Keeping the tank full of gas will help a lot. Keeping the bike indoors and warm will help even better. Condensation forms on a cold can of Coke. The same happens inside a cold gas tank. Please rate my answer. Thanks.

Please keep in mind that I am attempting to diagnose a problem with your appliance without being there and with very little information.
My first guess is you will need to replace the water valve. How fast is the water coming out. If it's a trickle, you have a bad water valve. If it is flowing as hard as it flows when the ice maker calls for water,
there could be a problem with the switch inside you ice maker is bad and continues send a signal to the valve to keep sending water. You can check this by unplugging the ice maker from inside the freezer and if the water valve stops sending water. You will need to replace the part inside the ice maker or replace the whole ice maker.

some water is left to keep the drum seal moist.

you should not be able to see the water.
