Blenders typically have a service life ranging from 10 to 15 years for heavy-duty models. When these units stop working, it is generally time for a new one. Proper maintenance not only helps to provide a more consistent blend, but it also prolongs the blender’s service life.

Although these units’ sealed motors usually require no maintenance, there are simple steps operators can take to keep blenders running smoothly.

Keep all components as clean as possible. This entails wiping the exterior down with soap and water regularly. Keep the container and blender’s base as clean as possible before and after use.

Do not use hoses or any water pressure for cleaning as this can damage the motor and impact its operation. Blender bases are not dishwasher safe or submersible. Clean the container by running fresh water and ice through it.

With older blenders or in high-volume operations, routinely check the container for cracks. The blades should turn easily with just slight resistance. They should be cleaned often to ensure the quality of the blend.

Use food-grade lubricant, rather than vegetable-based oils, for greasing lubrication points to avoid gumming up the mechanism and gear freezing.

Blenders rarely require service since the upper bearings are sealed. The biggest issues that occur with this equipment happen if there is excessive play with the bowl’s cutter assembly. This can cause liquid seepage into the bearings and motor, creating major issues and leading to an expensive fix. Signs service is needed include unusual or excessive noises, abnormal vibrations or leakage.

Some of the mistakes many operators make include pulling the container off the motor base before it stops rotating completely or trying to put it back on while it is still running. Both can damage the unit.

Because blenders are not pricey pieces of equipment, major failures typically lead to replacement. Service tends to take place on-site, although some repairs are shop jobs.
