So, I'm having two separate issues with an FX-STP pump:
1. It's making a 'grinding' noise when on. This noise doesn't happen when I don't have the roller head on it, and it persists through mulitple (brand new) roller heads.
2. It's started randomly accelerating to extremely high speeds, then seizing and stopping. It does this only when I have the 'clip' holding the tubing in place; however, it does it no matter how weak the 'clip' tension is, and modifying tubing length hasn't helped.
Video below; anybody have any ideas?
