First post here guys but have been reading for a while.
So, after attending the aroma festival in sydney a few weeks ago I made an impulse buy on gumtree. My em6910 pump was playing up so I thought instead of fixing that I would just look to see what was around.
Ended up with an ecm giotto that I found on gumtree for $600 which was already stretching the budget.
I completely dismantled it and citric acid bathed the boiler and associated pipes along with mushroom nut. There was some scale in there but not too bad I thought.
Pressurestat was playing up so replaced that.
Every shot I pulled on it had thin crema no matter what, horrible watery taste too. The pump didn't have a nice quiet hum when extracting so I dismantled that and cleaned it,put it back in and there was an improvement but only minor.
Ordered a new pump and put that in yesterday and now there is a definite improvement in taste, however, still thin crema.
So this is the problem now, prior to the new pump and pstat there was some hissing/flash boiling once heated, but now there's only about 1 second of hissing and then nothing. So now I'm thinking the temp is too low.
So I need some advice! I'm pretty tired of it and don't want to put too much money into this as it was a stretch already.
Could it be a heating element problem? It seemed to boil alright before the pump change.
I'm thinking of just selling it as I've had enough but thought I'd see if anyone has some ideas?
Btw, grinder is a mazzer mini, fresh beans weighed to a tenth of a gram.
