My 2-year old mechanika IV water pump (from reservoir) fails from time to time. Either during coffee making, before or after, pressure drops to 0-2 and water no longer flows.
It has been in service 2 times now and they do not find the cause because they cannot reproduce the problem. Everything points to a faulty relay or something else in the control box, so I want to replace the unit (quote for 350€ installed!).
It is coded Gicar M2004 9.9.06.30G00, which I cannot find online.
I do find 9.9.06.30G01 and G02. Newer Are these newer versions of the same unit?
