Diagnosing Your DeLonghi Machine

DeLonghi Coffee Machine

When assessing the issue with your DeLonghi machine, it is important to recognize the signs of water pump issues. Therefore, here is a list of initial troubleshooting steps before moving on to repairing the machine:

No water flow from the brew head

If there is no water flow from the brew head, this can indicate a blockage or an interference in the water delivery system. 

An issue with the water flow can prevent the machine from making coffee altogether. 

Grinding noise without water flow

If you hear a grinding noise, this can mean that either the water pump or grinder is impacted. If this is the case, brewing coffee may not be possible. 

The grinding noise can indicate mechanical damage to the machine, which may get worse with use. 

Erratic water flow

If you’re able to make a cup of coffee but it’s inconsistent (in terms of taste and quality), water issues relating to pressure may be the source.

Leaky water pump

Leaky water pumps can place water in other parts of the coffee-making system, which can damage the inside of the coffee maker. Leaky water pumps can also damage the electrical components of the coffee maker. 

Loud noises from the water pump

Loud noises usually relate to parts misaligning or potential mechanical damage to the coffee machine. If you hear loud noises over time, this may indicate pump failure!

Coffee machine not turning on

If your coffee machine isn’t turning on, this could be an electrical issue or an internal problem. 

It is important to rule one out before checking the other. If you are investigating electrical damage, be sure to dry all areas associated with electricity!

Coffee machine displaying error codes related to the water pump

Error codes mean that the machine itself has detected an issue. If your coffee machine is displaying error codes relating to the water pump, this is the likely root of your problem.

Common Reasons Why DeLonghi Coffee Makers Fail to Pump Water

DeLonghi Coffee Makers

There are multiple reasons why a DeLonghi coffee maker might fail to pump water, such as clogging, airlocks, and water tank issues. Check out the full list below: 

Clogged Water Intake

In order to identify clogs in the water intake system, check if there is water flow from the brew head. If there is no flow, this could indicate a clog in the system. 

Also, if you hear any strange (grinding) noises, such as a struggling pump, you may be dealing with a blockage.

To resolve clogs, try inspecting and cleaning the water reservoir. Once that is complete, check the water tubes for any blockages. Finally, descale the machine to remove any mineral deposits. 

Faulty Water Pump

A faulty water pump is usually accompanied by a lack of water flow and unusual noises. Also, if you touch the water pump, it may be vibrating or moving excessively, which can indicate that it is working harder than it should be. 

If these issues persist after troubleshooting and consulting the user manual, consider pump replacement. It’s always a good idea to consult a DeLonghi technician before replacing any parts of your machine. 

Airlocks in the System

An airlock refers to trapped air in the water system that prevents it from working properly. Airlocks can prevent water from flowing and block the machine’s ability to produce a cup of coffee. 

In order to fix an airlock, turn off the machine and look into the water reservoir. 

Then, you may want to fill the water reservoir and jostle the machine around (tilt, tap, shake, etc.) for a few minutes. Following that, run water through the machine to see if it was an effective fix. 

Water Tank Issues

Water tank issues are quite common and can be caused by improper insertion or a need for refilling. Every few days, make sure to check that your water tank is aligned properly and filled adequately to avoid issues.

Scale Buildup

Limescale (mineral) buildup is often encountered with coffee machines that are used frequently. Limescale can impact water flow by blocking it, which is why the descaling procedure should be done regularly. 

Faulty Electrical Connections

Beyond mechanical and chemical issues with your machine, there could be an electrical origin to your problem. Electrical connections can be impacted through problems with the power supply, overheating, water leakages, and faulty switches.

Solutions and Fixes for Your DeLonghi Machine

Solutions and Fixes for Your DeLonghi Machine

When cleaning your DeLonghi machine, split it into two parts: descaling and coffee grounds. 

Use a descaling liquid to remove mineral deposits that can accumulate with use. Once that is finished, clean out the coffee ground from the machine and rinse it well. 

To unclog your machine, check the coffee filter, grinder, and water system. If all seems to be clear, the issue may be mechanical or electrical. 

To assess if your water system is working well, run water through the machine and take note of how the machine handles it! 

When to Seek Professional Repair

Sometimes, DIY fixes are not enough to repair your faulty machine. In this case, it may be time to call a professional. 

You may be able to bring your DeLonghi machine into your purchasing store for service, or someone may be dispatched to your location to assess the damage.

Regular Cleaning and Maintenance Schedule

It is crucial that you regularly check and clean your machine. It can be easy to forget these maintenance tasks, so it might be wise to create a weekly or biweekly cleaning schedule to prevent issues. 

Conclusion/Final Thoughts

It is important to understand and maintain your DeLonghi coffee maker to ensure consistent performance and delicious coffee every time. 

Make sure to check your coffee maker weekly to ensure that it is working properly. If you’re consistent with your upkeep, your DeLonghi coffee machine will continue producing cups of coffee worth savoring!

Can I repair my DeLonghi water pump on my own?

What should I do if my DeLonghi machine is still not pumping water after troubleshooting?

You should contact DeLonghi directly to have a professional look at your water pump. They may even identify a non-water pump issue as the source of your troubles!
