Hello Mike, I just got this e mail and I am sorry but I have to run out and
will give a detailed response this evening when I can read it carefully. But
don't worry we can get this taken care of right away and it won't be a big
deal.ThanksTodd SalzmanWhole Latte LoveTodd,I've got an issue with my Brewtus
II (purchased 12/26/07 from WLL)that is stumping me.I've got a slow drip out of
the E61 group. I've got an intermittentgurgling sound in the bowls of the
machine. I get an occasional overpressure of the steam boiler, which causes
the pressure relief valveto open. And, lastly, if I've left the machine on all
day, when Icome home from work and pull a shot, I hear one of the
boilersrefilling (not sure which one) before the shot will start. I also
notewhat appears to be more water than normal in the drain pan.Today I pulled
the cover off, started up the Brewtus from "coldirons", and watched what
happened.1. The steam boiler heated up normally. Once up to pressure, the
heatcycled on at about 1.2 bar and off at about 1.4 bar. I noted that
thedripping from the E61 group started once the boiler hit about 1.1bar. The
dripping was continuous after that. The dripping was fromthe bottom valve of
the E61 group with the handle in the full-downposition. If I put the handle in
the mid position, the dripping willcome from the portafilter.2. The water
boiler heated up normally after the steam boiler came upto pressure. The water
boiler reached 95 and then the water and steamboilers cycled on and off
normally to maintain temperature/pressure.3. The gurgling sound appeared to
emanate from the steam boiler.While listening to the noise I noted bubbles
going through the plastictube between the heat exchanger outlet on the steam
boiler and theinlet on the water boiler. If I disconnect the pump control
switch(so that the pump will not come on with the handle in the
full-upposition), the gurgling sound increases appreciably, as does the flowout
of the portafilter. Eventually the flow will go to nothing butsteam. The
plastic tube between the steam and water boilers will havenothing but steam in
it. If I re-engage the pump, water will againflow through the plastic tube,
but it will take 10-15 seconds to getwater flow at the portafilter.4. I get
random occurances of over-pressure on the steam boiler,resulting in the
pressure relief valve opening at around 2 bar. Thereis no apparent pattern to
when this will happen.5. My habit patter when I pull a shot is to first
pre-heat my cupwith water from the steam boiler and then pull the shot. When I
comehome from work (Brewtus has been left on all day) and open the valvefor hot
water to pre-heat my cup, I'll get immediate flow of hot waterfrom the wand,
but then I'll hear one of the boilers refilling forabout 20 seconds. I'll also
note that the drip tray seems to havemore water than expected from my normal
routine of shot pulling.I had thought that perhaps there was a crack or a
pin-hole in the heatexchanger which was allowing boiler pressure and steam to
migrate intothe water boiler and group head. However, if I put a blank in
theportafilter and run the pump, I do not see a concurrent increase inpressure
in the steam boiler, which should occur if there were a crackor hole in the
heat exchanger.I'm stumped. Hope you can help. I figure the p-stat at a
minimumneeds to be replaced, but the dripping and gurgling and waterconsumption
has got me scratching my head.Sincerely,Mike

Todd,
I've got an issue with my Brewtus II (purchased 12/26/07 from WLL)
that is stumping me.
I've got a slow drip out of the E61 group. I've got an intermittent
gurgling sound in the bowls of the machine. I get an occasional over
pressure of the steam boiler, which causes the pressure relief valve
to open. And, lastly, if I've left the machine on all day, when I
come home from work and pull a shot, I hear one of the boilers
refilling (not sure which one) before the shot will start. I also note
what appears to be more water than normal in the drain pan.
Today I pulled the cover off, started up the Brewtus from "cold
irons", and watched what happened.
1. The steam boiler heated up normally. Once up to pressure, the heat
cycled on at about 1.2 bar and off at about 1.4 bar. I noted that the
dripping from the E61 group started once the boiler hit about 1.1
bar. The dripping was continuous after that. The dripping was from
the bottom valve of the E61 group with the handle in the full-down
position. If I put the handle in the mid position, the dripping will
come from the portafilter.
2. The water boiler heated up normally after the steam boiler came up
to pressure. The water boiler reached 95 and then the water and steam
boilers cycled on and off normally to maintain temperature/pressure.
3. The gurgling sound appeared to emanate from the steam boiler.
While listening to the noise I noted bubbles going through the plastic
tube between the heat exchanger outlet on the steam boiler and the
inlet on the water boiler. If I disconnect the pump control switch
(so that the pump will not come on with the handle in the full-up
position), the gurgling sound increases appreciably, as does the flow
out of the portafilter. Eventually the flow will go to nothing but
steam. The plastic tube between the steam and water boilers will have
nothing but steam in it. If I re-engage the pump, water will again
flow through the plastic tube, but it will take 10-15 seconds to get
water flow at the portafilter.
4. I get random occurances of over-pressure on the steam boiler,
resulting in the pressure relief valve opening at around 2 bar. There
is no apparent pattern to when this will happen.
5. My habit patter when I pull a shot is to first pre-heat my cup
with water from the steam boiler and then pull the shot. When I come
home from work (Brewtus has been left on all day) and open the valve
for hot water to pre-heat my cup, I'll get immediate flow of hot water
from the wand, but then I'll hear one of the boilers refilling for

I'm stumped. Hope you can help. I figure the p-stat at a minimum
needs to be replaced, but the dripping and gurgling and water
consumption has got me scratching my head.
Sincerely,
Mike
