What To Do When A DeLonghi Espresso Machine Not Working?

To fix a Delonghi machine, you have to define which part of the DeLonghi espresso machine not working first and whether it can be fixed without intersecting all the internal parts opened. DeLonghi is one of the most popular generalist brands in Europe; however, buyers report that it has a few common flaws that are easily fixed.  

It can be a heating problem, worn-out power switch, noise, defective frothing, water leakage, or simply a system failure from operating. For the customers’ convenience, I’ve listed a few typical issues and associated troubleshooting guides. 

Let’s move to the full, detailed instruction now!

Top Reasons and Answers To The Question of DeLonghi Espresso Machine Not Working

Although it may be inconvenient, there are a few pieces of your machine that you need to carefully inspect in order to prepare a perfect cup of coffee.

It Stops Brewing

If your DeLonghi Coffee Makers & Espresso Machines aren’t brewing, you might want to see if the brew heads have become clogged. Brew heads, used in traditional espresso machines, must be cleaned by damp cloth from time to time. 

A brew head is a device that dispenses water into the coffee. On the other hand, the brew head has filter baskets that hold the ground coffee, which can become clogged with time if users often use finely coffee grounds. The portafilter is also frequently clogged when water is pouring into the coffee.

Every week, you must clean the brewing parts of your DeLonghi coffee maker. You can accomplish this by removing the brew unit from the machine and thoroughly rinsing it with warm water under the faucet. Avoid using detergent solution because it is bad for the brew structure. 

You should also clean the area where the brew unit was removed, as there will be a significant amount of coffee residue remaining.

It Does Not Dispense Water

A coffee machine that cannot properly pour water through coffee grinds or pods is a defective gadget. This issue may arise as a result of a malfunctioning pressure pump.

The majority of DeLonghi espresso coffee makers include 15 bars of pressure. It doesn’t always pull off the adequate pressure to make a high-quality espresso. When the pump becomes clogged and leaks, it ceases pressurizing the milk or freshwater. 

To alleviate the lack of pressure, it would be best if users can alter the filter basket. You will achieve consistency if you update this component. That is most likely how you will troubleshoot this issue.

Another reason for this might be due to the water tank. If users do not properly position the water reservoir, an air bubble can form in the system, obstructing water flow.

You can use 2 to 3 cups of dispensed water to remove air bubbles from the machine. Check for limescale development if you notice the DeLonghi coffee maker isn’t pumping water anymore. 

It Does Not Froth 

The clogged froth and dirty steam wand are usually responsible for 70% of the causes of this problem. If milk type or cup sizes aren’t the problems, frothing or any temperature difficulties with the milk are most likely due to the machine’s need of cleaning.

Scale on the inside of your coffee machine might impair its performance and ability to heat and produce adequate steam; thus, it may need a descaling solution.

It Stops Heating The Coffee

The broken thermoblock function must be the most common complaint that DeLonghi users have been giving to the company’s customer service and technical support. 

Thermoblock is the most common and widely used water heating technology, which boils water in a matter of seconds and keeps your coffee hot for almost two hours. We can never heat water if this heating element breaks. The machine then serves you coffee at room temperature, which many consumers dislike. 

To prevent this from happening, you first need to decalcify with a solution of 1 tablespoon white vinegar or lemon juice to 5 cups of water. The acetic acid from vinegar and lemon will swipe the leftovers that obstructed the Thermoblocks’ proper flow and operation. As a result, the water will flow properly, leading to sufficient water temperature stability.

However, if you don’t want to use vinegar for descaling, you can use cheap descaler liquid as a substitute.

Hot water that does not come from the coffee machine might also be due to the damaged fuses. Even if you replace the fuse right away, the new one will most likely blow as well. You’ll need to replace the temperature control thermostat to ensure that excessive heat is detected and properly handled.

When replacing a thermostat, ensure that it has the same voltage and working temperature as the one you’re replacing.

It Has No Coffee Supply or Slow Drip

It’s possible that your machine’s grind setting is having some issues if it does not deliver coffee or deliver very slowly. Another factor could be a coffee overdose. When this happens, remove the handle from the machine’s group head and press the volumetric key. You can use the coffee amount dial to prevent this problem.

If the water is running fine, it could be the grind setting or a coffee overdose. However, if pushing the volumetric key causes the water to dribble or run irregularly, the problem could be more serious, and you’ll need to call in a specialist to investigate.

The Coffee Has Bland Taste 

If you have supplied adequate coffee grounds or even buy the most expensive coffee pods, but the final taste is still very weak, you might want to look at the grind setting.

If the grind setting on an espresso coffee machine is set too coarse, the coffee may pour faster, resulting in less optimal coffee extraction. To fix this, change the grinder on your machine to make finer coffee.

The shots will be erratic if you use stale coffee for the ground setup – either too coarse or fine. Fresh coffee will result in more uniform shots, as well as fewer changes to the grinder.

As for the pod coffee, it might not be the capsule cradle’s fault but the excessive water supply or wrong coffee strength settings. Keep in mind that the ideal espresso has 1 oz to 1.35 oz of liquid. 

Bottom Line

Whether you are looking for solutions to why your DeLonghi espresso machine not working, I highly recommend thoroughly cleaning all machines’ parts before contacting any technical support. As you can see, half of the solutions for the problems above are solved by descaling or cleaning. 

Simply follow the advice above, and you will find your precious and efficient coffee machine working just fine. However, be careful of electric shock and avoid any parts relating to the heating circuit, and contact a specialist or customer service right away.

      It seems that your coffee machine is old, so brewing is slower. When you add excessive amounts of ground coffee or an over-fine grind, it can cause the filter basket to overflow. Or your unit need cleaning.
