Am getting error "E1" on the Cosori display when trying to use it. This error means the NTC sensor is open circuited,...

The replacement battery kit came with two gaskets/spacers with adhesive. But the adhesive (pre-applied to gasket) was useless - not very sticky. The watch would not stay together. Heating the watch and pressing it together was no help. What did work was to clean the gasket and watch faces with some 99% isopropyl alcohol, then use B-7000 multi-purpose adhesive as mentioned above. Let it set for 24 hours with clamping pressure applied to watch. I've worn the watch for 5 days so far and keep checking to see if the face is loosening up. So far no problems.

Part 1: first attempt Here's what I found with my Nutra-Ninja. Melted plastic after unscrewing the wheel driving the blades. Note: It's a left-hand thread. Applied some silicone spray and this eliminated the vibration (for now anyway, will see how it goes). Part 2 second attempt: Took the extractor blade assembly apart (again) to work on reducing the amount of noise coming from the blender. The model I'm working on is the "Nutra Ninja Nutri Bowl Duo with Auto-iQ Boost", models NN100, NN100A, NN101, NN102 - these model numbers use the same motor and extractor (blade) assembly. Removed the bearing retainer: Pulled out blade assembly, cleaned and lubricated it with silicone spray. Then reassembled. Reduced the noise level a little bit. To see where the most of the noise is coming from, the motor can be run without the extractor blade assembly installed. Just attach one of the cups and briefly run the motor to see how much noise is generated. Compare to noise level with extractor blade installed. For my...

Thank you for posting this guide. Had to break the plastic "fingers" to remove the base.

Krups must have a special tool for this purpose.
