Topic: Espresso machine go *Boom* (9 msgs / 578 lines)
1) From: Cj. Aberte
Ok.. don't split a gut! It didn't fall down it blew up!
Quite frightening too. Least you believe that the only people with 
pressure problems are those with piston machines, I'm here to say it 
'taint so! With a shower of sparks (a nice sized boom) and a hearty 
hi-ho silver the Andreja went over the hill Thurs. night last! No, no 
warning no leaking no weird sounds.. Just sitting in the LR after 
supper having just drawn a couple and away it went.
Fortunately it's not a big problem (self fixable with a new part) and 
under warranty. Should be back in service early this coming week. 
Meantime refreshing my press pot techniques - glad I own something 
that doesn't require electricity to get a cup!! Meant to keep the 
press pot for "hurricane" withdrawl emergencies - didn't think about 
this happening. Meantime it's helping us all cut down. Between 
laziness (time fixing) and clean up, there are times we'd rather do 
without than "fuss"... Helps cut back the stash faster and getting 
MUGS instead of cups is addictive.

Wow, what self destructed? From your story sounded like an electrical
failure of some sort, did it attempt suicide and blow it's electronic
controller "brains" out?

Apparently it blew out some kind of pressure regulator. The sparks 
were when it showered a bit of steam/water out the vents (apparently 
cause it was sparking top/back area after the blow out..).
We pulled the plug immediately (yeah, like you're going to leave 
something with pressure in it already spitting, in a puddle with an 
electrical connection immediately behind it...) ! Once we cooled 
it, released the pressure we looked up the manual (yep, there *were* 
contingencies for such things happening..) and after wiping up the 
puddles and drying out the area, we plugged it back in (following 
directions to do so). The pressure just kept climbing (since it 
reheated we're assured the electrical didn't burn out). Unplugged it 
again after it passed twice normal boiler pressure and turned it in 
as a *bad* 'spresso machine having a tantrum.
Nothing unheard of as they knew *exactly* what happened and with a 
few moments questions knew what we needed and had it off the shelf 
and on it's way to "shipping". Unfortunately it sits right at the 
back door and has to take it's daily abuse as we walk past and vilify 
it's decision to go "further" south. Best of all - if such things 
have bright sides - it didn't happen early morning or when we have it 
set to heat before we get home! *THAT* could have been dangerous if 
not downright disastrous! After the fact we have begun thinking about 
NOT preheating it when we're not conscious or around!
No lessons here unless it's be careful around electrical equipment. 
Hopefully it might run around the brains of people that leave their 
machines on all the time...

That sounds bad enough, but when I read the subject line, the first thing I 
thought was that the boiler had exploded.  That would have been a lot worse.

5) From: miKe mcKoffee

That's what I thought too, which I've never heard of happening before. As in
pstat failed stuck on (which is what happened) PLUS safety over pressure
valve didn't open. But safety valve did it's job. Worse case scenario if
pstat sticks on normally would be machine would keep venting steam/water
until tank low and then low water safety would shut machine down. One of the
big advantages of direct plumbed machines is no tank to run out of water,
disadvantage in case of boiler pstat failure would of course be no tank to
run out of water so would keep feeding water and venting steam until problem
detected! Which is one reason why even though the Bricoletta commercial
rated for 24/7 operation I use a timer. If pstat happened to fail during
timered warm up would result in about an hour venting flooding the
counter...

WOW!  I have a "Premium" and leave it on 24-7.  Even forget it when away on
short trips........always hot and ready; direct plumbed and drained.  Never
think about a catastrophic melt-down!
Now, I am worried!  I hate to cycle it on and off each day as I think it
works innards excessively with the expansion and contraction of heat up/cool
down.
Hmmmm, this needs more consideration!
Thanks for the in"flux" of paranoia, 
Mark

Sounds like a bad pressurestat. Usually a fairly inexpensive and  
simple fix--Jerry the tech supervisor at Caffe West  walked me  
through it over the phone.

After replacing my Livia's p'stat, I thought I could leave it on  
24/7. But after a hellish, sooty and sweaty couple of hours spent  
changing an ossified grouphead gasket (despite having religiously  
backflushed and periodically cleaned the shower screen), I have  
decided it's no biggie to shut off the machine at bedtime and when  
nobody who drinks espresso is at home to use it.  I also store the PF  
out of the machine when it's turned off and parked loosely on the  
grouphead (just tightly enough to mate and heat up--get your minds  
out of the gutter, thank you) when it's on, to prolong the life of  
the rubber gasket.

Could be worth a think or two. After the sparks I was more worried 
about the possibility of fire, but then once upon a time I left a 
skin overflow for a mere 2 mins. After that mess I'm not sure I'd 
want to come home to even a pressure valve release venting for an 
hour! Even discounting the mess and water damage I'd be much more 
scared of problems with the electrical plug (timer in - that's what 
could have sparked along with the insides) immediately behind it. The 
situation might be totally unique as far as the setup goes and the 
location. I'd wonder what would have happened if we hadn't been there 
to turn it off (with the boiler pressure 2x recommended and still 
climbing at the time of testing) had it not been turned off...
Maybe a total freak of a situation (at least the way it blew). I'll 
at least hope so. I know after reading the list for over a year quite 
a few of you out there are leaving various models on while 
"unsupervised". My guess would be that someone in the business (doing 
repairs and sales as well as parts) is going to see the failures that 
occur more often than we hear about them. I wouldn't put too much 
emphasis on the fact that they knew which of the few things that can 
actually go wrong with any given machine happened and diagnose it 
quickly. I'd also think that if this were something that were a real 
problem, we'd all be hearing cautions about NOT leaving machines on. 
I'm darned *sure* that SM's wouldn't be allowing it's customers to 
use equipment without cautions under such situations.
  I'm not sure I'd be leaving anything on that heats that much (ever 
seen what can happen when a hot water heater blows?) for extended 
stays away - I remember a X-mas holiday away with a power failure and 
broken pipes all over the house as well as a frozen relief valve on 
the water heater... Might be ok, but I'd think if it were as little 
as over a weekend I might rethink adding it to my list of things to 
do when shutting down.
Heck, here in the lightning capital of the US, when we leave the 
house over an afternoon we start thinking about pulling plugs and 
turning off the "electrics" in the house (during the summer 
primarily). It only takes replacing a kitchen full of appliances or 
one strike getting your media center to make it easier to think ahead 
than regret it... again . And while insurance will help, it's 
still a royal pain (and you cover what insurance won't).
Oh, well.. enjoying a *great* Ethiopian Yirg I got nearly a year ago. 
Light roasted and what a refined taste! Actually getting back into 
the joys of "press potting" again! Change will do me good. ;)
