| 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”. |
|
| Causes can be: |
|
| * Clogged boiler - the subject of this guide |
| * The water flow impeller can be blocked |
| * Water pump may be worn out. A sign of worn out pump is rinsing problems on startup. |
| * Something else... |
| 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. |
