How do i remove the bottom power cord holder on my Breville 800BLXL 2-Speed Blender

SOURCE: Blender stops after about 2 seconds on every setting

correct - replacing the cord is suggested and simple.

Mine does this as well... 5 seconds of operation and then OFF.
My guess is this is a fail safe where the blender is turning itself off to avoid overheating and what could potentially cause this overheating is the blender is struggling to turn the blades. What could cause this struggling of turning the blades I am guessing is a lack of oil in the blades rotating parts.
If you hold the circular blade part and turn it, you'll probably find that its hard to turn? Mine is... and I oiled it up a bit and found I got a bit more usage out of it... although only temporarily.
Ideally I need to pull it apart and oil it properly.

SOURCE: blender will not run. the power button is lite but

There is a 10 Amp thermal fuse (SF129E) that is supposed to create an open circuit when the motor windings exceed 133 C degrees. Although this fuse should close again when the motor cools down it can become perminantly damaged. Locate the fuse by following the black leads from the coltrol board to the motor brushes. It's inside a cloth insulating sheath secured against the windings with a metal strap and two ty-raps. I bypassed the fuse with a wire instead of replacing it. It would probably just blow again sooner or later. p.s. you need a T10 Torx screw driver to disassemble (screws under rubber feet) $3 at ACE hardware.
