Avast K1 Kalk Stirrer not stirring

[Jipolley]

I’ve attached the video, but the top piece is spinning but the actual shaft that goes down to the stirrer stops with minimal resistance (from the Kalk at the bottom). What’s the fix for this? Is it buying the Avast Kalk mix I just discovered or need a whole new unit? Only been running it for a year

looks like there is a set screw that needs to be tightened.

I'll try that. Thanks!

Update if anyone else ever runs into this issue with the Avast K1 Stirrer: If your stirrer’s gray shaft spins freely but stops under any resistance, check the connection between the shaft and motor. I removed the motor and shaft assembly and found that the two retaining screws were no longer gripping the smaller shaft securely. I pulled the gray shaft out, coated the end with superglue, reinserted it into the motor coupling, and let it set. It has worked perfectly since.

Sorry we missed this Joel. If the superglue doesn't hold long term please email us and we can help further. We recently reengineered this part to be significantly stronger and it now uses all 316 stainless steel threads and hardware so it will not strip out over time.

Got it! If it fails again I will reach out

As an aside, not all kalk is created equal, some brands just don't spin well in my K1. Even with your fix, you still don't want to over tax the motor.
