Hello All,
Hoping someone might be able to shed some light on this.
Got a Sunbeam EM6900 that has, to date, been faultless in its operation (rare, I know) other than a new GH seal, which was an easy fix. A few weeks ago, I was making a brew in the double basket. Freshly ground from EM4800 grinder at usual setting, levelled, tamped with usual pressure. About 2/3 of the way through the extraction, there was this "clunk" & "fizz" and coffee starting pouring out of every little gap in the GH. The needle on the pressure gauge instantly dropped back to zero.
My initial thoughts were:
* Maybe I had simply overdosed the basket (I sometimes cram a wee bit more in, just for an extra kick!);
* Had the grind too fine;
* Tamped too hard.
* Combination of all three!!!
So I adjusted the grind a few notches to slightly coarser, tamped slightly easier and didnt overdose. The result was a drinkable brew with considerably less crema which extracted quite watery.
In the last few weeks, I have adjusted grinder back to usual setting (pre-problem), whilst still not overdosing and tamping too hard. Results still not great, and have had this same problem a few times since. Last night was the latest - thought Id try my "ideal" way of doing things, but again I had coffee everywhere!
So Ive deduced that really the problem seems to be in the machine, not the user. Can anyone help me with this? The machine has been great till now, and being my first unit, any problem is new to me.
Appreciate any assistance / views on this.
Cheers,
CF.
