Topic: brew pressure gage problem (4 msgs / 200 lines)
1) From: HarleyNew LoRyder
Hello One and All-
I have an Andrja Premium. I do regular plainwater backflushes and I do 
cleaner backflushes. The machine makes 2 to 6 shots a day. I have used it 
for about 2 1/2 years now.
The brew pressure gauge started doing crazy fluctions while making a shot of 
espresso. Now it does nothing while making a shot. I have seen it with 
pressure on it after the machine has been on for awhile but not used. I have 
seen it read some pressure if the machine is on long after a shot is done.
I moved to Florida about 2 years ago and was using filtered tap water, for 
about a year. I realized after research that was not good because the water 
here is so hard. I now use only RO water.
Does anyone know what may be cause my brew gauge not to be working? I do 
know how to pop off the shell of machine...any help on diagnosing the 
problem would be greatly appreciated.
Thanks,
H.L.

maybe ya got too many bugs in your eyes from riding without goggles...
seriously, the machine may need to warm yo a bit longer. You can also try t=
he old automobile gauge trick ( I don't know how old you are so you may nev=
er have had to do it)
take your middle finger and thumb and flick the gauge when you turn on the =
machine.
Just flick it a couple of times and I bet it comes on!! Having driven old s=
ports cars all my life it works; I even had to do it in my Dad's old, old F=
ord (found on road dead) truck.

maybe opening and cleaning the connection will do as will.

I'm with Ginny on this one. Give the gauge a good thunking and if it doesn't
work it's plugged, lost its seal, has damaged linkage...
Now if you're one of those fellows in my neighborhood who have drawn a
correlation between diminished testosterone, straight pipes on a v-twin, and
riding to cure insomnia, I rescind this information.

Mr. LowRider,
A couple of thoughts from another Andreja Premium owner: 
The advice is good to tap or flick the gauge to see if the needle mechanism
is stuck although my first thought is that the hard water you used for the
first year of the machine's life has probably clogged the capillary tubing
which feeds the gauge pressure.  Having replaced my gauge and capillary
tubing already, I am familiar with this plight.  A recent previous post
discussion revolved around the gauge fluctuating wildly with the pump
pulsations and the possible remedies.
You could disassemble the gauge and capillary tubing and soak it (the
tubing) in an appropriate descaling solution even full strength white
vinegar then use compressed air to be certain the tubing is open throughout
and also dry; reconnect and tighten firmly careful to not collapse the
tubing with the ferule compression fittings.  You could also (I recommend)
purchase a new capillary tubing which is much longer in length than the
original and as such should minimize the fluctuation problem discussed
earlier.  I think the tubing is $10 at Chris' Coffee or maybe Tom and Maria
are supplying parts now.  Cheap fix!  If the gauge is at fault, then the
entire assembly is somewhere around $55-60.  Since you know how to
disassemble the shell already, the gauge and tubing is easily accessible.
Another comment, good quality R.O. water is devoid of most dissolved solids
that, to some degree, contribute to great tasting coffee.  Also, low TDS
R.O. water is ION hungry and will, over time, attack the boiler and other
metallic tubing, pump, etc. in your machine.  Some alkalinity is good for
the boiler as well as the taste of the water!  I also use an R.O. system to
supply water in a direct plumb configuration and additionally route the
water line through a 10" Calcite filter element that is just about right for
all these concerns.  Once again, the filter housing and calcite element is
available through Chris' Coffee but probably through a number of other
outlets as well.
