The water from the group head is uniformly distributed over the coffee baskets thanks to shower screens. Replacements are needed as time goes on because they wear out and get clogged. Every year, most machines get this done, although it's typical to do it every 3-6 months on the most frequently used equipment.
Companies like IMS have produced incredible shower screens that help with water distribution while also reducing the quantity of coffee oils generated back into the group, which has recently been a hot topic. Specialty coffee shops and top-of-the-line coffee-machine manufacturers have swiftly embraced these new technologies. Even though they're a lot more costly, we think they're worth the investment.
It's common practise to remove the screws or bolts that hold up shower screens, except in cases where the shower screen is held up by an actual seal on the shower head itself, in which case it's necessary to remove the seal in order to replace the seal.
The sticky residue of coffee may be removed by back-flushing the machine (with back-flushing detergents) before removing the screen.
Growing Importance of Coffee Machine Shower Screens
Shower screens have been a major emphasis for high-end coffee machine manufacturers in recent years. These shower screens make a huge difference in the taste and aroma of your morning coffee. Because the water passes through the whole coffee puck in a shower screen, it would help to extract espresso more consistent and evenly.
Prior to removing the shower screen, it may be simpler to back-flush the coffee maker (with the proper back-flushing detergents). Most of the coffee oil that might clog the screen and cause it to malfunction will be removed in this manner.
Cleaning up Shower Screens
Before cleaning up the coffee machine shower screens, it's important to note the different types. Some shower screens are easy to clean and maintain, you could take it down with a screw driver. Consider using the Rhinowares Coffee Screen Driver to assist with the dissembling.
Other shower screens do not have a screw inside, these are fixed by the group seals. To remove the shower screens, you may need to use the Pick & Hook Tool to take down the group seals before remove those shower screens for either replacement or cleaning.
