How to install replacement part

Well our krups type 575 just went on the blink aswell. So I thought I'd take a look inside .I started by unplugging unit and removing the 4 rubber spacers, then removing the torque (# 20 Torque with hole in center screwdriver) Then I placed thin flat screwdriver through the slats in the bottom keeping the motor from rotating ,thus I could unscrew the rubber knob with teeth counter clockwise .So finally could remove outer casing .It seems the print out board on ours is fried so I hooked the power source directly to the motor and reassembled . Now it blends fine only one speed ,fast ,it is turned off and on by the switch on the wall. Hope this can help in some way good luck.

There is a slit in the middle of the bottom of the blender. You turn the gear drive until the metal slot in the shaft lines up with the slit. Put a flat head screwdriver through the slit into the slot in the bottom of the shaft. Now hold the screwdriver to keep the shaft from turning and remove the gear drive. It took me a few tries, but it finally came loose.

You need the remove the old gray rubber knob. I did it in a barbaric way just hacking at it with scissors. Once you've removed all the rubber, you can use pliers to remove the remaining metal base. Once that's removed, place the new piece on the post and spin it on. Most important, spin clockwise to loosen, not counter clockwise like most items.

The old gray rubber part is left-handed threaded. To remove it just turn it clockwise like you are trying to tighten it. You make have to take the bottom of the blender so the wheel doesn't turn.
