AS00009453 Genuine Anti Drip Valve for De'Longhi Coffee Machines, DeLonghi Non Drip Valve Replacement

Stopping the drip once your cup is full is the job of AS00009453. This genuine De'Longhi anti drip valve shuts off the flow cleanly when the machine stops delivering, so water or coffee doesn't keep trickling out. It suits De'Longhi coffee machines, but we don't have a model list on file yet. Match the number with your old valve or your model's exploded view before ordering.

Anti drip valve problems in De'Longhi coffee machines

When the pump stops, there's still water and coffee sitting in the lines. The anti drip valve closes as the pressure drops so that leftover liquid stays put instead of running out. As the seal inside wears or picks up scale and coffee residue, it stops closing fully. You may notice coffee or water dribbling from the spout after brewing, puddles on the drip tray grille between cups, or a drip tray that fills while the machine sits idle. Descaling can free a sticky valve, but a worn seal needs a new valve.

Changing the anti drip valve

Unplug and cool the machine, then empty the water tank and drip tray. Locate the valve using your model's exploded view and take a photo of how it's oriented, because a valve fitted backwards won't seal. Fit any new seals that come with it and push hoses fully onto their spigots. Run water through a couple of times and watch for drips.

Questions about this part

My machine still drips after descaling. Is it the valve?

It's a likely suspect. Descaling clears scale, but it can't restore a worn or hardened seal. If dripping continues after a full descale, a new AS00009453 is a sensible next step, provided your model's parts list shows this number.
