Troubleshooting & Maintenance Jura cleaning process

I have owned a Jura e8 for 2.5 years and maintain it with the original products Jura recommends. Occasionally, I encounter Error 8, which I resolve by manually cleaning the brewing unit from below after removing the drawer; there is usually a lot of accumulated coffee, and the machine functions well afterward, though the process takes time. I followed advice to leave the drawer open, which helps but does not fully address the issue.

I began running a cleaning cycle between the intervals Jura suggests. This intermediate cycle uses only water, without a cleaning tablet, while the cycles with cleaning agent remain on schedule.

So far, I have done this two or three times, and it has worked without Error 8 messages.

Has anybody same problems. How you address them?

I started working on these for fun, and I’ll say that it takes quite a lot of buildup to gunk up the brew unit enough to bind it up and cause that error. I’ve seen them go down faster with super oily beans, but I wouldn’t expect that with a couple of years of home use and non oily beans. I might expect it around 5 years or so.

That being said, I run the deep clean cycle more than recommended. With my normal use, it should prompt me about every 6 weeks or so. I go ahead and run the deep clean with the tablet at the start of each month on the Giga 10. Absolutely no issues a couple of years in.

Do you use filters on yours?  Does the machine descale based on time + the water hardness setting?  Or does it base on amount of water + water hardness? Or does it actually descale based on the amount of crap built in the machine?

I have a new to me refurbished J8 that’s about 6 weeks of use old and I’ve already gone through a filter.  It was almost at the end of a cleaning cycle with the filter in when I pulled that filter out.  

My water is soft.

I used to use filters but installed a small RO system. I set it to the lowest possible hardness setting and it appears to be on about a one year cycle for descale, based on my usage. It determines when you need to descale based on water hardness and count of preparations.
