Blind screen for backflush (58 mm)

Head cleaning of the coffee maker is one of the usual espresso machine maintenance that we should not forget. Clean the head by replacing the strainer in the lever with a so-called " blind sieve " (no holes), pouring a detergent such as Urnex Cafizu into the lever, putting it in the coffee maker and running. By having no way to flow through the water, it circulates inside. After about 3 seconds the coffee maker is switched off, the water leaks out through the back valve. Repeat approximately 10x. The same must be done with a classic strainer so that everything rinses with clean water.
