You will have to tip the machine over to drain some of the water, so play it safe by letting the Keurig rest.
All of these parts are easy to detach by hand. The funnel requires a little force if you haven’t removed it before, but you don’t need a screwdriver or any special tools to remove it.
Be aware of hidden components. The coffee pod holder consists of 2 parts, so pull them apart and wash them both thoroughly. Also, wash the lid on the reservoir tank. Use the soapy water and a microfiber cloth to clean the outside portion of the machine as needed.
When you reinstall the coffee pod holder, notice the tab slots inside the Keurig. Align the tabs on the funnel with the slots to easily slide it into position.
The pod holder consists of 2 parts. Pull them apart by hand to access a funnel hole in the larger, topmost piece. Sometimes washing the part in hot water is enough to clear out most of the debris. Double-check the funnel after washing it to make sure it’s free of debris.
The needle pierces the K-Cups during the coffee-making process, so it will always be accessible in the top part of the Keurig. You can’t harm the machine by cleaning out these holes. None of the mechanical or electrical parts are there, so take the time to clear out all of the coffee grounds.
Any water stuck inside the machine will also come rushing out as the clogs clear, so work over a sink to avoid a big mess.
Another way to access debris in the water line is by sliding off the cover on top of the machine. You will see a big, clear tube running towards the needle. Squeeze the tube a few times to force out any dark-colored sediment stuck inside of it. [4] X Research source
To avoid damaging the coffee maker, always dilute the vinegar with water. Never run pure vinegar through the machine. Keurig sells a commercial descaling product. It is effective, but it tends to be a bit pricey. If for some reason vinegar doesn’t work, the descaling product is worth a try.
If your Keurig does not run without a K-Cup inside it, put a used K-Cup in the coffee pod holder. This causes a little bit of coffee or tea to run through the machine, but it doesn’t prevent the vinegar from clearing out the lines. The vinegar smell gets a bit overwhelming, but it is a safe and natural way to flush out calcium scales. As long as you dilute the vinegar, the liquid won’t be acidic enough to damage the Keurig.
Go through this process at least twice, even if the Keurig seems to be in working order. Any vinegar left over may degrade the line, but more importantly, it will foul up your next cup of coffee!
Another way to test the machine is by sprinkling some baking soda into your mug. Baking soda fizzes when it comes into contact with vinegar.
