Scale build-up in coffee machines is a costly problem and replacing filters on a regular basis in line with the volume of water you are using is essential. If you have hard water in your area then a proprietary water filter must be installed. If you notice not all steam jets working use a paper clip to clear short term but remove the tip and clean with a detergent such as Puly Milk when possible. When frothing milk wipe the Steam Wand with a Clean Damp Cloth, when finished, purge the wand with a blast of steam to clear any milk in the Tip. Steam Nozzles should be kept clean at all times. Basically you cannot backflush machines unless it has the equivalent of an E61 grouphead. Perform this operation only if your machine is equipped with a 3-way Solenoid Valve that allows Back-Flushing from the Portafilter though the Grouphead to the Drip Tray. It also helps to do this ‘ Back Flushing’ throughout the day without the detergent. Remove the Portafilter and rinse then put back on the machine and run the coffee delivery switch for 10 seconds, stop take the Portafilter off and rinse and repeat this 4 times. 10 seconds, stop for a few seconds and run again. Run the coffee delivery switch for approx. Place a teaspoon of Grouphead Cleaner such as Puly Caff into a Blind Filter Basket in your portafilter.

Common practice is to soak filter baskets in hot water and a detergent, such as Puly Caff overnight to dissolve deposits. It is a fact that more problems are caused by poor cleaning than actual machine failure so a simple daily routine will help the machine, along with keeping up the quality of coffee.
