Our Blender jar unit had teh bottome blade and seal failed. Rubber seal broke, what do I need to order to get those replacement parts? The jar itself is all good.
Hi Jim, thank you for getting in touch. The jar blade and its part come attached with the jar, part number PS12745729. You may need to replace it to fix the issue. We hope this solves your problem!
