Introduction
Work in progress - a partial solution. Feedback welcome. The partial part is that I still may have to stop the “Rinsing” process during startup. But I can make coffee.
My machine is a Saeco Exprelia full automatic espresso machine. It has been working well for several years, until the stream of espresso dried up into drips and then finally ceased. I should of course have descaled it in time!
The message to me was error E05 which means “Water circuit blocked”. This error code can also happen in other ways. The water flow impeller can be blocked too.
The YouTube guide “How to clean your Saeco brew unit” is a good idea to check first.
The completely blocked boiler would no longer allow the descale program to complete.
Time to do some disassembly.
