Insider Tip

The Keurig coffee machine continues to grow in popularity, but there are still advantages to using an old-fashioned type of coffee maker.

Low Water Levels in Water Tank

Your first step should be checking the water supply to see if it’s low. If it is, your machine won’t be able to boil the cold water. To correct this, check the water levels. Most coffee pots and appliances will have water lines to show you how much fresh water is necessary. Going past these lines can stop the flow of water, so don’t overfill. Whether you use tap water or bottled water is up to you.

If you’re displeased with your morning cup of coffee, you might be wondering, “Why is my coffee maker making weak coffee?” It’s a more common problem than you might think.

A Clog in Your Water Pump

You might think that the flow of hot water is enough to clean out your water pump and the system attached to it. This couldn’t be farther from the truth. A clogged water pump is likely due to a build-up of some sort. If you don’t clean your water reservoir regularly, there will be issues down the line.

A water pump is vital for the water flow of your machine. Cleaning your water pump isn’t a huge hassle. Just follow the step-by-step guide provided by the manufacturer.

Level of Noise from Normal Operation

There is a certain level of noise that you can expect from your coffee maker. This could be a clicking noise caused by the pump motor. It could also be a buzzing sound present when brewing. Just because you hear a small level of noise doesn’t mean that anything is wrong.

As long as you have enough tap water in the water tank, you should be good to go with minimal effort. If you feel like the level of noise is unreasonable, reach out to the brand for directions on troubleshooting.

Warning

Use caution when handling a Keurig coffee machine since exit needles can easily puncture human skin.
