Have Flow But Getting No Flow Error
If your Gaggia Anima Prestige is able to produce coffee or steam, but it is showing a No Flow error, review the following instructions to restore functionality and clear the error message.
In some situations, you will be able to get flow through the machine for all functions, but the machine thinks there is no water flowing through. There is a device in the machine called a flow meter, and it tells the machine when water is flowing through or not. The device operates by having small fan-like blades spin when water passes through it. If those blades get stuck from excessive scale buildup or debris, then they will not spin. As a result, even though water is flowing through the machine, you will get a flow error.
If your machine uses a water filter, temporarily remove it from the water tank and add Gaggia Decalcifier to the water tank. The descaler needs to work its way into the system to start dissolving the scale buildup in the flow meter. You may have to keep restarting the machine so that it can keep attempting to prime, which will draw the descaler/water solution into the system. If at any point you are able to clear the flow message then you will want to perform an immediate descale of the machine. After you have descaled, run 4-5 tanks of plain water through the hot water function for the wand in order to ensure the system is completely free of debris.
