How To Clean The Water Lines
Now that we’ve gathered the necessary supplies, let’s start the process of cleaning out the lines. The first step is to shut off the water supply to the fridge and unplug the refrigerator.
If there is a water valve behind your fridge, then you can easily turn the valve off to stop the water flow. If not, head to your basement or wherever your main water valve is located, and turn that to the closed position.
The second step is to use the screwdriver to remove the water line from the rest of the fridge. Often, this will mean taking off the back lower screen of the fridge and then detaching the water line from the other components. A small wrench can be useful here if required.
If you want to clean the dispenser reservoir too, now is the time to remove it (it’s usually found behind the crisper). Drain all the water out, and run a vinegar solution through the reservoir of about 1 cup of vinegar per gallon of water.
Afterward, run clean water through the reservoir multiple times to ensure there is no lingering vinegar. Because no one likes vinegar tasting water.
From there, run about 3 cups of distilled white vinegar through the water dispenser and icemaker lines. Use the funnel to help get the vinegar into the lines, and let the vinegar sit in the lines for about 10 minutes. Using the clamps can help ensure the vinegar doesn’t leak out.
After we’ve let it sit, it’s time to drain the lines. For the ice maker line, we’ll want to drain the vinegar back out and then run clean water through it several times before reattaching it.
For the water dispenser line, we’ll run the vinegar all the way through the system, out of the water dispenser, and into an empty bowl or another receptacle. Then we’ll also flush the line with clean water multiple times (probably close to 10 glasses of water for each of the lines).
From there, it’s time to hook both of the lines back up. Once you’ve reattached the lines and everything is back in its original place, run about 5 or more gallons from the water dispenser into an empty jug, and dispose of the first batch of ice. Again, this is to ensure all contaminants and vinegar have been flushed out of the system.
