If your alfi Big Spender 2.20 l leaks at the spout, the riser tube, tap, or sealing ring may be worn. Here's how to diagnose and fix the drip.
Quick answer
A leak at the spout of your alfi Big Spender 2.20 l usually means the riser tube, dispensing tap, or sealing ring is worn or misaligned. Replacing the entire spout assembly with the alfi Steigrohr, Auslaufhahn, Dichtungsring set is the most reliable fix.
Why the spout leaks and not the body
The Big Spender 2.20 l is a vacuum-insulated dispenser, so leaks rarely come from the body itself. When you see liquid dripping from the spout area, the problem is almost always in the dispensing hardware: the riser tube that draws liquid up, the tap that releases it, or the sealing ring that keeps everything tight. These parts wear over time, especially with frequent use or if the dispenser is cleaned aggressively.
Diagnose and fix the spout leak
- Symptom: Liquid drips from the spout when the tap is closed, or a steady stream appears when you press the dispensing button.
- Likely cause: The riser tube (Steigrohr) may be cracked, the dispensing tap (Auslaufhahn) may have a worn seal, or the sealing ring (Dichtungsring) may be flattened or misaligned. Any one of these can cause a drip. Inspect the sealing ring first—it's the easiest to check and often the culprit.
- Corrective action: Remove the old spout assembly by unscrewing the retaining nut (if present) or gently pulling the assembly apart. Install the new alfi Steigrohr, Auslaufhahn, Dichtungsring set (part number 9111002009). Ensure all components are seated firmly and the sealing ring sits evenly. After reassembly, fill the dispenser with cold water and test for leaks before using it with hot drinks.
- When to stop or choose another option: If the drip persists after replacing the entire spout assembly, the leak may be in the dispenser body or the vacuum seal—neither of which is user-serviceable. In that case, contact alfi customer support or consider replacing the dispenser.
