Re: Silvias a gusher
Fair enough MM67,
That would have to be a pretty rare occurrence though, given the millions of Rockys thatll be out in the wild. Id still reckon its most likely cause would be related directly to the burr-plates themselves or the way they were originally fitted. And even though the guy in question makes suggestions to the effect that it might be possible to cross-thread the top burr carrier and continue down in this fashion until the burrs are close enough to grind, Id like to see the bloke who could do that and hed have to be a lot bigger than Big Arnie.
Like I mentioned above though, there have been a few instances of MDF grinders suffering from this problem but I still believe that it is most likely due to the manner in which the burr-plates have been fitted. They are precision ground cutting tools and must be fitted with care and accuracy and I guess if even the slightest unevenness during fitting occurs, then grinding for consistently good quality espressos is going to be difficult. Ive even noticed warnings on the care needed to properly fir new burr-plates to a number of large commercial grinders, so I guess its a problem that is recognised and manufacturers have seen the need to draw attention to it.
Cheers,
Mal.

Re: Silvias a gusher
Hmmm,
I remember reading one about a Gaggia MDF with this trouble MM67 but not a Rocky.... To the best of my knowledge
. I suppose it would be possible if the burr plate(s) were incorrectly fitted but otherwise its hard to imagine given the amount of metal involved in the burr carrier system and the length of thread engaged between them :-?.

Re: Silvias a gusher
There is a thread on HB about a rocky where the burrs wernt quite parralel and made it very difficult to get good shots. maybe something going on.

Re: Silvias a gusher
One month old and in repairs? Was it brand new? Did you leave it on steam or without water?
For future reference, if its new and you havent done anything to bust it yourself, you are entitled to a complete refund or replacement (YOUR choice) and dont have to accept a repair if you dont want to. Of course, if you like the ppl and trust them it doesnt matter but I hope you werent talked into having a repair when you would have preferred a straight out replacement.
Four steps off burrs touching on your Rocky (which is also new?) seems incredibly fine to me, I think my burrs touch close to zero and I run my Rocky at 8-10. If the coffee is tasting good, maybe leave it, but if you still think its possible its not quite right I would take it back and ask for a replacement. You are entitled to one.

Re: Silvias a gusher
after discussions with Renzo the guru it appears that my lil gurl mightve had a lower temp then the new boiler somehow, one of those one in a zillion things which confused the heck out of me.(which isnt all that hard to do)
In the end problem sorted, changed all my settings and seems to be working better now on a 2 clicks from true zero on bullwinkle.
Thanks for the help everyone.

Re: Silvias a gusher
Sullo,
My Rocky is set on 4 and it always has hovered around that value, so using a low setting on the rocky is nothing new to me. My Silvia, which is a few years old will spit and hiss after being on for a while once the brew switch is hit and then settle down to a nice stream. The Silvia is very sensitive to the amount of coffee in the PF. If the pf is not dosed fully then it can lead to fast pours. You need to have the level of the puck in line with the line around the inside of the basket after tamping. Ideally it should be a little hard to load the PF as I have found that a PF with a little resistance to being locked in gives the best pours. This doesnt mean arm wrenching hard, just a little more resistance than an empty one. If you remove the pf again you should have an impression of the screw and slight impression of the shower screen.
Cheers,
Matt

Re: Silvias a gusher
Are you sure the zero is where the burrs meet?
You may find it goes into the negative.
With it empty and without turning it on, can you adjust the setting below zero?

Re: Silvias a gusher
seems weird that a grinder that has so many steps is set so low, its on 1 now?
this obsession sometimes does my head in!
I should take up stamp collecting, much less stress.......
Nahhhhhhhh

Re: Silvias a gusher
As long as your grinder will allow you to do so keep going finer with the grind until the timing is right and go from there by taste.

Re: Silvias a gusher
Although this may be too much information, I have the best partner in the world, for lots of reasons, but for this thread one reason, is she has no way of pmsing or any mood related symptons. Yes I truely am a lucky man(thank god she doesnt read this!)
But Im convinced bloody Silvia does, tempramental lil witch she is.
Id so love to jam a PID or something in her, but Ive a promise not to mod till warranty expires

Re: Silvias a gusher
the invoice only lists 1 x betsy boiler, so Im guessing thats all that was changed?
I would imagine that if the thermo was replaced that wouldve been listed too?
appreciate the feedback here guys

Re: Silvias a gusher
Mmmm...
Doesnt sound like they have been swapped....
But maybe the new boiler comes complete with new thermostats (and this one is hotter)..... or they refitted the old one but it isnt making good contact with the boiler..... so it switches when the boiler is at a higher temperature.

Re: Silvias a gusher
Ill have to check the hot water one tomorrow as shes is off for the night, told her off gave her a pointed gesture etc. Without pf it initialy does spit and splutter a lil bit then 10-15 secs I get the familiar 5 streams of hot water. But thats given me a good thing to check, Ihavent lifted the lid to see what he did, was hoping for the best.
If he has mixed them Im not going to be very happy arggg, what a week.
thanks Mal
