I have an aquamedic sp 3000 i picked up at the last brs meeting and i read through the instructions and maintenance to find the hose needed to be lubricated. went bought some vasaline and lubed it up but it still wont turn. I take out the hose and it turns just fine so i know the rotor itself is in working condition. Here's a pic. any troubleshooting help would be appreciated to narrow down the root cause of this problem. Maybe i applied to much vasaline? or maybe i didn't apply enough idk?
