Making coffee at home is convenient because you can enjoy it without waiting in a drive-through line. However, if your De’Longhi Coffee Maker is not brewing, you may need to troubleshoot the machine. Although it can be frustrating, there are a few parts of the machine that you should check before you can enjoy a perfect cup of coffee again.

De’Longhi Coffee Maker Troubleshooting

According to 33 Coffee Makers, there are a few simple steps you can take to expedite the troubleshooting process for your De’Longhi Coffee Maker. First, make sure that the machine is plugged in and that the water reservoir is filled. If there is not enough water in the reservoir, the machine will not brew. Additionally, check if the filter basket is properly placed in the holder. Sometimes, the filter basket can be loose or off-axis, so ensure it is correctly positioned. Finally, check that the carafe is sitting firmly on the warming plate before pressing the brew button. After going through these troubleshooting steps, your machine should brew correctly. If not, further inspection of the machine may be necessary.

Clearing a Clogged Brew Head

If your De’Longhi Espresso Machine is still not brewing, it is possible that the brew heads are clogged. According to 33 Coffee Makers, the brew heads dispense water into the coffee and can become clogged along with the filter baskets and portafilter. To address this issue, check the brew heads and portafilter once a week to ensure they are not clogged. If they are, use a pin or a long, sharp object to remove the coffee grounds.

Properly Positioning the Water Tank

Another aspect to consider during De’Longhi Coffee Maker troubleshooting is the water pumping. If you notice that the coffee maker is not pumping water, check the positioning of the water tank. If the tank is not placed correctly, an air bubble may form in the system and block the water supply. To address this, remove the water reservoir and empty it. Then, check the compartment for any coffee remains or debris and clean it. Refill the reservoir and put it back in place. Finally, turn the machine off and on to restart it. To remove air bubbles from the machine, dispense 2 to 3 cups of water. If the coffee maker still does not pump water, check for limescale buildup, as this can also cause the issue. If limescale is present, the machine will need to be decalcified.

Infuser Is Jammed

Another possible cause for your De’Longhi Coffee Maker not functioning properly is that the infuser may be jammed. As stated by Crema Coffee Garage, the infuser, also known as the brew unit, is situated adjacent to the grinds bin, where the used coffee grounds are ejected. It is common for the used coffee grounds to become stuck either in the upward or downward position during the brewing process. Additionally, the infuser can become jammed if there is a power interruption while brewing, if a door is opened at an inappropriate time, or if any other part of the brewing procedure is interrupted.
