⚡ TL;DR — Quick Answer

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

What Causes Leaking Water?

KitchenAid coffee makers feature programmable timers and thermal carafes.

Step-by-Step Fix

Follow these steps specifically for Kitchenaid machines:

  1. Inspect the Kitchenaid brew group gasket for cracks. Replace with OEM part if damaged.
  2. Check internal hose clamps. Kitchenaid 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 Kitchenaid units, this requires professional repair.
