I have a Electrolux ESL 4135 (built in) dishwasher.
I have got the flashing fault code” come up saying the Siphon is blocked. No where in the instruction booklet does it tell you how to unblock it, or even where that is, and the instruction manual seems to indicate it is something I can do myself, like cleaning the filter.
The actual code number isn’t a code number as such, it is one of the programme buttons, specifically the “Quick 50′ wash” button which is flashing and the manual indicates that this means there is a problem with a blocked siphon.
