A good practice
Cleaning
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.
Filter Basket
Clean daily in hot water. Common practice is to soak filter baskets in hot water and a detergent overnight to dissolve deposits.
Grouphead
Clean daily, in the morning. Place a teaspoon of Grouphead cleaner into a blind filter basket in your portafilter. Attach the portafilter to the group. Run the coffee delivery switch for approx. 10 seconds, stop for a few seconds and run again. Do this 4 times. 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. It also helps to do this ‘Back Flushing’ throughout the day without the detergent. This is only possible if machine as
3-way solenoid valve (E61 grouphead)
Steam Nozzles
Steam Nozzles should be kept clean at all times. When frothing milk wipe the Steam Wand with a clean and preferably damp cloth, when finished, purge the wand with a blast of steam to clear any milk in the nozzle. 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.
Water Softener
If you have hard water in your area then a proprietary water filter must be installed. 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.
