Krups Type Blender 577

Hi u can order you're parts at this site :::
cheers www.ereplacementparts.com

Check the blade assembly if it is loose tighten it up. If it is worn out or cannot be tightened up then buy another jug complete with blade. If it is the glass jug model then the blade assembly is available without the jug and they also have a replaceable seal at the base.

SOak them in hot water with some dawn soap maybe that might do the trick.

Krups Blender 577 - first try not easy but next time it will be.
Replacing the rubber coubling is extremely difficult with this model.
After almost destroying the air in/outtake grill on the side in pursuit of a good lock of the axe I tried so hard to use a nose plier to grab the post and unscrew the coupling counter-clockwise but it just did'nt fit (it needs to be long and narrow/needle like). So I ended up cutting off more rubber on the coupling and also cutting of plastic from the black plastic cover which is just under the rubber coupling. In the end I was able to cut that plastic so that I could actually take off the whole casing (you need a torx 20 with a hole in it)with the rubber coupling still attached and detach two power cables so that I had much more space to properly grab the post and then it was very very easy to unscrew it counter-clockwise. But up until then I lost my insanity twice :-).
The next time it will be easy.

I am sorry, from the description I cannot work out what seal you are referring to. Please can you let us know the exact model number of the blender and whether the jug is glass or plastic?

This place has spare parts in the U.S.

They deliver worldwide. I am in Australia and just ordered the rubber ring and on the list there was the glass jug.

My blender would do that if I didn't screw the jar on firmly enough. Sometimes the action of the blades will even loosen the bottom from the jar during blending, so I always hold the jar handle while the blending is going on. That way if it starts to undo, I can twist it back tight. Before I learned that trick I had smoothies leaking out the bottom - what a mess! Also make sure you put the gasket/seal on in the right order. If it's in the wrong place it won't seal correctly.

I carved off the rubber with a knife; inserted a flathead screwdriver throught the slot in the bottom to hold the gear in place; using pliers I unscrewed (COUNTERCLOCKWISE) the rubber gear.
