It is perfectly normal for the pressure to rise for the reason JohnB stated. Todd Salzman Whole Latte Love
If it truly is building to 10 bar when you're not pulling a shot, something else is amiss. Hi Benjamin I had the same issue on my rotary pump machine when I got it and was convinced something was wrong. The pressure increase however is totally normal and is caused by the water expanding in the water boiler when it is heated up. The water boiler is totally saturated (no air in it) so a small increase in volume by the water results in a large increase in pressure. Excess pressure if bled of via the OPV valve so nothing to worry about. The rise in pressure is mostly evident when starting up, as that is when the largest volume difference is going to show up, but you will notice it a minute or so after pulling any shots.
