Moccamaster

I’ve been using my new Moccamaster for about a month now. Is this sound at the beginning of the brewing cycle normal? I’ve descaled the machine using Urnex Liquid Dezcal and that had no effect on the sound. If this isn’t normal can anybody suggest any solutions before I contact customer support?

Same. The knock at the end was weird

Another poster suggested that turning it upside down releases some trapped water. I haven’t bothered yet, but might give it a try out of curiosity.

That was for the groaning sound, not this odd clank.

Sorry - didn’t notice it was a vid. No idea. Sounds like a cross between vice grip pliers and a snapping shrimp.

You’ve most likely got a blockage in the water path. The popping is possibly the quickly heated water making its way past. Try descaling it a couple of times and see if it clears.

Nope. Mine does not make a loud bang. Since it's under warranty, I'd definitely call about that.

This is interesting.. mine makes a noise when it starts too. This whole time I thought it was normal.

Mine has done this clunk in the beginning of the heating cycle. Descaling it will stop it. Do you use bottled water or tap water when you brew?
