🔍 Why This Happens
Root cause analysis for your blender's not blending properly
The blender blade assembly in your blender has reached the end of its service life through normal wear. Cutting edges dull, drive components stretch, and plastic parts become brittle with age. This is a wear item designed to be replaced periodically — like brakes on a car. Your blender's symptom matches the 80% pattern for this specific wear failure.

🛡️ Prevention Tips
How to prevent your blender's not blending properly from happening again after this repair.
Don't overload the pitcher with frozen ingredients — the motor and blade assembly are designed for a specific load range.
Add liquid before frozen or hard ingredients to reduce strain on the blade assembly and motor.
Hand-wash the blade assembly and gasket — dishwasher heat degrades the rubber seal over time.
Inspect the gasket seal monthly for cracks or deformation. A worn gasket causes leaks that can seep into the motor housing.
When replacing worn blender blade assembly, compare the old and new parts carefully. Excessive wear on the old part may indicate an underlying alignment or loading issue.
