Thanks for your video. I got the same issue on my new machine. The rotary pump sounds louder than a vibe pump. But the dealership said it is normal. How can I show them the sound is abnormal? Thanks
Wot Tanker I have the same issue . It’s about year old . I was told the the pump maybe needs to be adjusted . Have to open it and take a look at it I guess .
Wot Tanker I‘ve found a workaround for my pump noise! There is a screw on the bottom right to adjust the pump pressure. Starting the pump and pushing the screw solved the noise, so I slapped a rubber band around the adjusting screw and another screw on the buttom. But I would be glad to compare your pump noise to mine, I‘ll upload a video this weekend.
