La Marzocco GS3 makes weird sound like always heating

#1: Post by **gs3_beginner** » July 29th, 2020, 5:26 am

Hi there!

I have seen this thread La Marzocco GS3 constantly heating and I am not really sure if my GS3 has the same problem. I have uploaded a video of my GS3 in which you can hear and "see" the noise (I can hear it very well on my phone, I hope the quality is good enough) you can find it here:

Does someone here know why my GS3 sounds this way?
Is there a piece I can replace or check?

Best regards
D, gs3_beginner

Video is silent.

Hi!

Yes, the Video is not the best at all. I have tried to record just the sound without Video. This should be better:

The video it self is just black.

It looks like the youtube upload removes a lot of the audio quality

How old is the machine?

Mine started to sound like this after about 6 years. A brand new steam boiler element fixed the issue.

Around 4.5 - 5 Years

So you replaced the boiler like the one in the image? Did you do it by your self? Is there a way of testing, if its really the boiler?

The steam boiler heating element is this part.

It's difficult to be sure from the video, but it sounds like a steam boiler leak from the vacuum breaker is not closing completely. If you remove the side covers and use a rolled up paper tube as a stethoscope, you should be able to pinpoint the source. Of course, the site's terms of service applies:

OK, I will give a try next week and keep you updated. Thanks!
