Several factors can contribute to your Delonghi coffee machine not pumping water. Let’s explore some of the common causes and how to address them:

Insufficient water level in the reservoir

One of the simplest explanations for a lack of water pumping is an insufficient water level in the reservoir. It’s important to maintain an adequate water level to ensure proper functioning of the machine.

To troubleshoot this issue, check the water reservoir and refill it if necessary. Always remember to follow the manufacturer’s guidelines for water level requirements.

A clogged water filter or coffee grounds can obstruct the flow of water through the machine. Over time, mineral deposits and coffee residue can accumulate, leading to reduced water flow. To address this, clean or replace the water filter regularly.

Additionally, ensure that no coffee grounds are blocking the water pathway. Clearing any obstructions will help restore the water pumping function.

Airlock in the system

Airlocks can occur when air gets trapped in the water lines, preventing water from being pumped. To release airlocks, you can prime the machine by following these steps:

  • Turn off the machine and unplug it.
  • Fill the water reservoir to the maximum level.
  • Place a container under the steam wand.
  • Turn on the machine and wait for it to heat up.
  • Open the steam wand and let water flow until a steady stream is achieved.
  • Close the steam wand and wait for the machine to heat up again.
  • Repeat the process until the water pumping function is restored.

Malfunctioning pump or valve

If none of the above steps resolve the issue, it’s possible that there is a malfunction in the pump or valve of your Delonghi coffee machine. In such cases, it is recommended to contact customer support or a professional technician for further assistance. They will be able to diagnose the problem accurately and provide the necessary repairs or replacements.
