Based on pointers from other posts here i understand my no steam issue is likely 1 of 3 things. The steam micro-switch is fine. Ive tested it for continuity and its all good. So I suspect either the steam pump has died or the control board is dodgy. 2 questions i hope someone can help with:
1. How do I test that the pump is operable given i cant get power to it? I figured continuity across the two connectors but that doesnt appear to work even on the brew pump which i know works. (Incidentally does anyone know what the Ulka pump model is that SB has used for the steam?...i read its a 4bar pump but thats all i know. its smaller than the brew pump but I cant quite see the identifier tag on mine without pulling the whole machine apart.
2. could the steam pump be successfully replaced with another ulka pump from an old breville or other donor machine? im talking a standard "15 bar" pump. I have a cheap old breville cluttering my bench that could finally serve a purpose! pump does the same job of pulsing water to prime the boiler during steaming in that so any reason it wouldnt work as a dedicated steam pump in the em6900?
any advise to these questions appreciated...
