So it seems like the Plum is dripping. This can happen due to a few circumstances. After the Plum pours the last glass of wine from a bottle, there can be a build-up of wine droplets on the inside wine circuit that can result in a small drip. Plum recommends removing an empty bottle once finished to avoid this.
A Plum may also seem to be dripping if the protective packing tape that runs along and under the spout is not fully removed. Wine can get caught if the tape is left on and will appear to be dripping.
During the removal process, the wine valve will open and wine can come out of the spout at any point, which is why glass is needed to be under for the entire time until the door opens. There can also be a build of wine crystals in the spout area and we recommend wiping the area with a soft cloth soaked in hot water or a soft bristle brush. There are three situations where the Plum can exhibit an undesirable drip:
Liquid adhesion around check-valve, resulting in 1 stray drip after a pour or a few drips after the Plum finishes pouring the bottle
Cork or sediment debris in the wine circuit, leading to a persistent drip of variable frequency
Bubbles in the wine - this will cause pressure to push a valve open, causing a drip
Occasionally cork debris can become stuck between valves; to solve this, go into Settings > Maintenance > Drip. The Plum will walk you through this process, but, it'll do a specialized pour with your wine, resulting in a perfectly drinkable glass and pushing out whatever is keeping the valve open and causing the drip.
If dripping persists, the next step is to finish the wine on the side that is dripping. You can do this by drinking through the bottle as you would normally or by going to Settings > General > Remove Bottle, then having a decanter ready as this will entirely drain the bottle.
Once the unit is free of wine, you should run a cleaning process. This uses the Plum cleaning kit, and you'll also need a large container for draining. Fill the cleaning bottle up to the neck with hot water (120F-140F), add 1 cleaning packet then closing with the provided cap shaking vigorously for 30 seconds, and follow the instructions on the bottle.
Then go to Settings > Maintenance > Clean then select the side. Your Plum will run cleaning from there. Once completed, this should resolve any dripping issues.
