My luvelo had a fuk up the other day, well i did. I vac sealed 4 steaks and had it set on dry, it sucked in blood and fuked the suction, would still seal, but no vacuum.
Being the mechanic i am i ripped it to bits, plugged it in and tested it out, the motor was still running but the pump wouldnt rotate, close inspection found the pump had overloaded and the glue between the pump shaft/piston and the electric motor had broke, i pulled apart, re-glued with super glue and let sit over night.
vac sealed 2 whole chooks and some sausages yesterday, never skipped a beat.
Just an FYI for y'all.
