A blender can leak because of a worn or misplaced seal, an incorrectly assembled removable blade base, a cracked jar or a lid that is not seated correctly. The cause depends on the blender design and where the liquid escapes.
Stop using a leaking blender. Switch it off and unplug it before checking parts that the owner’s manual allows you to remove. If liquid has reached the motor base, controls, cord or outlet, keep the appliance out of use and contact the manufacturer or a qualified repair service.
What Causes a Blender to Leak?
Some jars have a removable sealing ring around the blade assembly. If the ring is missing, damaged or fitted incorrectly, liquid may escape at the bottom. Other blenders use a different arrangement, so do not assume every leak calls for the same replacement ring.
KitchenAid’s jar-leak guidance identifies seal condition and assembly as possible causes for the designs it covers. Follow the instructions for your exact jar rather than applying one gasket orientation to every blender.
Inspect accessible jar and lid surfaces for cracks or visible damage while the appliance is disconnected. Glass or plastic damage can cause leaks, but a leak near the top can also come from the lid, its seal or overfilling. The location alone does not prove the cause.

How Do You Fix a Leaky Blender?
Start with the model’s troubleshooting and assembly instructions. Clean and refit only the removable parts identified there. If the manual provides for an owner-replaceable seal, use the specified part and install it exactly as directed.
Do not assume that tightening harder will solve a leak. The Vitamix S-Series manual, for example, requires its seal to be seated evenly and warns that overtightening the blade base can cause leaking. That method applies to the containers covered by that manual.
A cracked jar needs the correct replacement. Do not patch a food-contact jar with glue, tape or sealant, and do not continue using damaged blade or collar parts. Ask the manufacturer which replacements are compatible with the model.
Replacement cost and warranty cover depend on the product and the cause of the damage. Contact the seller or manufacturer with the model number and purchase details rather than assuming a new jar or blender will be supplied free.

What If the Blades or Controls Are Faulty?
Slow blades, a jam, unusual noise or controls that do not work can have several causes. Stop the blender and follow its troubleshooting instructions. Do not reach into the jar while it is connected to power or while the blades are moving.
Do not add WD-40, household grease or another improvised lubricant to free the blades. Do not open the motor housing or control panel to clean or repair internal parts. A leak or mechanical fault needs the manufacturer’s approved remedy.
Keep the motor base out of water. Clean its exterior only as the manual directs, and do not soak the assembled appliance to remove food debris. Removable jars, lids and blades may have different washing instructions.
If the permitted cleaning and assembly checks do not resolve the leak, arrange service. Vitamix directs owners with a leaking container to Customer Care. Follow the support route for your own blender before using it again.
