⚡ TL;DR — Quick Answer

Inspect the Delonghi brew group gasket for cracks. Replace with OEM part if damaged.

What Causes Leaking Water?

DeLonghi super-automatics feature adjustable burr grinders and self-cleaning brew groups.

Step-by-Step Fix

Follow these steps specifically for Delonghi machines:

  1. Inspect the Delonghi brew group gasket for cracks. Replace with OEM part if damaged.
  2. Check internal hose clamps. Delonghi machines often leak at 90-degree elbow joints.
  3. Empty and reinsert the drip tray firmly. A misaligned tray can trigger false leak sensors.
  4. Examine the boiler housing for hairline cracks. On older Delonghi units, this requires professional repair.

Frequently Asked Questions

Most leaks appear during brewing or shortly after, which helps you trace them to one seal or hose. Water leaking from a DeLonghi machine is usually a loose hose, a worn seal, or a drip tray that is not seated correctly. Dry the machine and trace where the water appears during a brew cycle — most leaks are repairable without a service visit. Full steps in our Leaking Water guide.

A leaking DeLonghi almost always comes down to three things: a loose hose, a tired seal, or the tray not clicked in. Run a brew with the housing off and watch where the water escapes, then fix that one part. The guide our Leaking Water guide covers each leak point.

To find a leak on a DeLonghi, dry the machine completely, then brew and watch. Water from the front usually means tray or wand issues; from the back, the boiler hoses. Most are seal or hose fixes you can do yourself — steps in our Leaking Water guide.

Leaks on a DeLonghi rarely mean the machine is done for. Check the tray seating, the water tank gasket, and the internal hoses. Trace the drip during a cycle to pinpoint the source, then repair that component. See our Leaking Water guide for the details.
