Delonghi coffee maker leaks water from the bottom suddenly, how can I identify the cause fast?

First, make sure the water tank is firmly in place. Leaks can happen if the tank is not attached properly. Check the tank for damage or cracks that could let water leak out.

Also, make sure the drip tray isn't full or out of place, which could cause it to overflow. ​

Next, look at the machine's internal parts. Hard water can cause minerals to build up in lines and valves over time, which can cause leaks. A descaling cycle can help get rid of these buildups.

If the leak doesn't go away, check the hoses and connections for signs of wear or looseness. Water can leak from the bottom if the hoses are broken or disconnected. ​

If these steps don't fix the problem, it could be something more complicated, like a broken pump or seal inside the machine. In this situation, it's best to get more help from De'Longhi's customer service.

They can give you advice based on your model or suggest a trained technician who can look at your machine and fix it.

If not, consider filing a complaint on Xolvie to raise awareness about the issue and inform others.
