Review on Jura 71445 CLEARYL Filter Cartridge by Gary Reed

I have had a Jura Z7 for about 3 years and regularly perform all necessary maintenance on the machine including cleaning and replacing filters. I have always used these original filters. I live in an area with very good water quality, the water quality is below 100ppm. Everything I've read said I don't need to descale if I use them regularly. Not true! This weekend my machine unexpectedly started a coffee brewing cycle, but nothing came out of the spout and water, and the dry coffee grounds were dumped into the grounds and water containers. Although I cleaned the car recently, I cleaned it again. All the water went straight into the tank, nothing through the spout (except some through the cappuccino spout). A google search revealed that it was a serious brew group fault that would be very expensive to fix. After further research, I found a Yelp review from HOTNCOLD in San Jose, California, where I decided to bring my car in for repairs. Some reviews said that HOTNCOLD recommends descaling despite using filters, so I decided to give it a try. I did the descaling with the tablets that came with the machine but I never used them. I had the same result with all the water falling straight into the container by the end of the descaling cycle. Suddenly brown water spurted out of the sink. I then ran another cleaning cycle and now the machine is working fine. HOTNCOLD fixed my car without touching it!
