![]() Then place the empty filter basket into the portafilter and run water from the machine through the basket. Use a pin to clear the small holes in the filter basket. The small holes in your filter basket can become clogged, preventing the flow of water. Try using less coffee in your portafilter basket and tamping it less firmly to allow water to flow through. If the coffee is tamped too firmly or the dose is too large, water will be unable to flow through the puck. It also means there’s some room for error when dosing your portafilter. The Breville Duo Temp Pro is a semi-automatic espresso machine, which means it allows the user to tweak and adjust the shot.

If espresso isn’t flowing from your portafilter, the culprit could be the espresso puck or the filter basket itself. There’s nothing more disappointing than dosing and tamping your portafilter, only to watch a weak dribble of espresso, or worse, nothing at all, flow from the machine. Problem: Coffee Is Not Flowing From the Portafilter Basket Clean the wand according to the instructions in your user manual. If this doesn’t get the steam flowing, use the wrench in the center of the cleaning tool (or any wrench that fits) to remove the tip of the wand. Insert this pin into the tip of the steam wand to try to clear out any blockages. Your Breville Duo Temp Pro came with a cleaning tool that has a small pin on it. If both of these easy fixes don’t solve the problem, there could be a blockage in your steam wand. If your steam wand isn’t producing steam or isn’t steaming sufficiently to create quality milk foam, don’t despair! First, check the simplest fixes: make sure that the dial is turned to “steam’ and that there is water in the tank. Problem: The Steam Wand Is Not Producing Steam Or the Milk Texture Is Poor Purchase a replacement pump like this one. It’s quite easy and inexpensive to replace the pump on your Breville Duo Temp Pro. If your flow rate is too slow, your pump may be faulty. Around 250-300 ml of water flow in 30 seconds at 10 bars of pressure indicates a good flow. ![]() If your pump is making unusual sounds or you feel that it isn’t pumping as well as it once did, do a test by running the pump with no portafilter in place. If your machine isn’t pumping water at all, and you don’t hear the sound of your pump working, it’s a safe bet that it needs to be replaced. ![]() These pumps are small and inexpensive, making them ideal for home espresso machines, but they have a lifespan of around 5-6 years, so it’s conceivable that your espresso machine will outlast its pump. The Duo Temp Pro uses a vibratory pump, which is a small piston that moves back and forth to pump water through the machine.

Solution 2: Change Your Tamping Technique Replace the shower screen and ensure that the water is now flowing freely from all around the group head, with no blocked areas. Remove the shower screen and clean off any debris. If the water doesn’t flow evenly, the problem could be a blocked or dirty shower screen. ![]() If you’re noticing channeling in your puck, try pulling out the portafilter to watch the water flow out of your group head.
