Posted Sun Oct 7, 2012, 10:42am Subject: LM gs3 idle pressure
Hello. Starting about 3 months ago, my GS3 grouphead pressure gauge began indicating a drop in pressure when sitting idle. It's a home machine, so I only use it in the mornings and evenings, but leave it on 24/7.
When brewing, the pressure is at a solid 9-9.5. However, afterwards, the pressure starts to drop after about 15 minutes and settles to about 3 bar after around 2 hours.
When I brew, the pressure goes back to 9-9.5 so no problems there. However, it used to hold pressure at 9 all the time. Questions are:
Does anyone else experience this?
Is it a problem? If so, is there an easy home fix?
The machine is 1.5 years old, purchased new. Thanks much in advance.
I wish I could tell you, but if it were mine I would have someone check it out. Any machine that changes it behavior like that has a reason.... Machines do things randomly just seem random to us. It always has a cause.

i just had a tech come over and do "standard maintenance", which involves changing all gaskets throughout the group head. All pressures are back to normal. I was a little shocked at how much wear happens in just 1.5 years of use. best to do this on every year i think. it's like having a new machine.
