Flushing the Water System: Use a sturdy container to depress and hold the water dispenser lever for 5 seconds and then release it for 5 seconds. Repeat the process until water starts to flow at a steady pass and all the air is out of the water line.
Use a hair dryer and thaw all the ice out then shoot hot water down the drain hole with a turkey baster to make sure the drain hole is clear. Once the drain hole is clear, you can put it all back together and you're good to go again.
To ensure you achieve clean water lines in the fridge, you must flush them. Using a small funnel, slowly pour two to three cups of distilled white vinegar into the tube that leads to the water dispenser. Let the vinegar sit in the reservoir for five to ten minutes to thoroughly clean the system.
Blockages are most likely to occur in the defrost drain, with the drain hole usually located at the bottom-back of the freezer.
You won't need any drain cleaners or harsh chemicals. Baking soda is enough to break up difficult clogs. Repeatedly flush the drain until the water flows freely. Check the Drain Pan: Ensure the drain pan at the bottom of the refrigerator is clean and not overflowing.
If you notice a pool of water at the Whirlpool refrigerator defrost drain location, you might be dealing with a clog. To unclog it, use a soft brush or a piece of flexible tubing to remove any blockage.

Remove the food and any crisper drawers. Mop up any excess water and remove the drain hole cover if yours has one. Use the unblock tool that came with your fridge (or else a pipe cleaner, straw or cotton bud) to remove the food and debris build-up. Replace the cover and turn your fridge back on.
While these sounds can be scary and seem like serious issues, the cause is usually quite benign. Most often, a loud sound coming from your pipes is caused by trapped air. By turning off your main water supply and running all faucets for 10-15 minutes, you force any trapped air through your water pipes.
Refrigerators/Freezers
For refrigerators without filters, flush water dispensers by running at least one quart of water. o If unsure of your dispenser's capacity, refer to manufacturer specifications.
Make sure the water supply is properly connected to a cold water supply and the water shutoff valve is fully opened. Check to make sure there are no kinks in the water supply line. A kink in the line can reduce water flow. Straighten the water source line to restore adequate water flow and pressure.
Place a bucket under the end of the water supply line. Turn ON the water to the supply line and check the flow. If the water flow seems weak or irregular, the problem is with the water supply. A regular, steady flow could indicate the water valve has become restricted or clogged.
One of the most common causes of water accumulation in your fridge is a blocked defrost drain. Modern refrigerators have a defrost mechanism to prevent ice build-up. During the defrost cycle, the melted water should drain out through a small tube.
Cleaning Defrost Drain Tube
You can flush out the drain hole with a solution made of 1 tablespoon of baking soda and 2 cups of hot tap water. Use a meat/turkey (bulb) baster to squeeze the solution into the drain hole and flush out the drain tube. When clear, you will hear water running down into the drain pan below.
Alternatively, you can defrost the water line with a hair dryer or by letting the refrigerator sit unplugged for upward of two hours. Restore power to the refrigerator and listen for the water supply to fill the ice mold. If the clog is anything but translucent, consult with a professional for help removing the clog.
The most common reasons your Whirlpool refrigerator is not working are a defective electronic control board, bad temperature control thermostat or a locked compressor.
Clogged Defrost Tube
If your fridge has water pooling at the bottom, the defrost tube is your MOST likely suspect. Your defrost tube is what carries the water all the way down to the drain pan where it eventually evaporates. When working correctly, it helps make sure your fridge has a smooth defrost cycle.
The drain hole can be found on the back wall of the of the fridge. Clearing the hole should just need a couple of pokes with the small plunger (this should be kept in the hole). If the issue is still not resolved, the blockage may just be a bit further down. Use a pipe cleaner in order to reach any deeper blockages.
