Profitec GO / GO 100 – knocking or rumbling noises during Fast Heat-Up?
Hi,
does anyone with a Profitec GO / GO 100 experience similar knocking or rumbling noises during the Fast Heat-Up phase?
My machine has been doing this more or less since it was new. The heating element has already been replaced once, but that didn’t solve it. More recently, Profitec inspected the machine and mechanically removed some scale from the heating element. It was noticeably quieter immediately afterwards, but after only a few days of use and very few shots, the noise is already back.
My tap water is quite soft (I regularly measure GH and KH), so I find it hard to believe that significant new scale could have formed within just a few days.
The noise itself doesn’t really bother me if it’s normal for the GO. My concern is simply whether it indicates an underlying issue that could get worse over time.
So I’m mainly interested in other GO owners’ experiences: Does your machine make knocking/rumbling noises during Fast Heat-Up as well? Would you consider this normal behavior?
I can also post a video of the sound for comparison.
Best regards and thx for help
Paul
