La Marzocco GS3 MP temperature curve and boiler offset

I just looked inside mine, I never knew there was a HX adjustment there. Did adjusting yours flatten the temperature profile? I'm very interested to try this as I have a Scace device to help dial it in. I'm only hesitant because I'm not sure how sensitive it is to get dialed in and there doesn't see...

La Marzocco GS3 New Firmware - Boiler Offset Issues

This has not been my experience based on measurements with my Scace. Although it's been over a year since I last tested, so I'm going from memory- inverting the offset from negative to positive, but keeping the value the same, is providing similar results from before I updated the firmware

La Marzocco GS3 MP temperature curve and boiler offset

I've noticed the exact same thing using my Scace on my GS3 since I purchased it. The temperature will slowly rise throughout the shot. Here is my hypothesis. All machine require a boiler offset because the group head naturally is cooler than the water in the boiler. The group acts as a heat sink, co...

La Marzocco GS3 New Firmware - Boiler Offset Issues

With the new firmware, the display will alway show the same temp as the programmed brew boiler temp. The offset is now invisible to the user. The machine treats the offset as the number of degrees to add to the programmed temp that the boiler requires to get the desired brew temp. Hence the need to ...

La Marzocco GS3 New Firmware - Boiler Offset Issues

After the firmware update if you don't update your offset setting, your actual brew temps with your current settings are now around 196-197F depending on the factory programmed offset. To brew at 199F, you will need to set your brew boiler temp between 204-205F

La Marzocco GS3 New Firmware - Boiler Offset Issues

No, this was not called out. I don't think La Marzocco USA was even aware of it until I emailed them. They said they were going to have to speak with the engineering team in Italy to figure out what's going on. So yes, if you don't update the offset, you're now brewing almost 6F cooler than you woul...

La Marzocco GS3 New Firmware - Boiler Offset Issues

I finally received an email back from La Marzocco USA. I don't think they were aware of this issue. They said they would let the engineering team in Italy know. Once they figure out what's going on, they said they would communicate it. If you feel better waiting, we should hopefully hear something f...
