Daily, weekly, monthly and yearly blender maintenance centers on cleaning. Unplug the unit and wipe it down with a clean, damp cloth after every use. At the end of the workday, wipe down the blender using a cloth and soap and water. Using a hose or water pressure can damage the motor. Regularly clean the blade to avoid tainting the taste of dishes with other flavors. Run fresh water and ice through the blender to clean the blade.
Weekly tasks include cleaning air inlet screens, which are on the side of the unit. Inspect the blender’s drive clutch and cutter blades. It’s important to note the cutter blades won’t rotate properly if the drive clutch is sticking. Replace loose or worn cutter blades. When the application requires crushing ice, the blades will wear down more rapidly. In addition, operators should routinely check the container for cracks.
Inspect blades and drive couplings, both of which operators can replace on-site without a service tech.
For units with lubrication points, use food-grade lubricant for greasing. Never use vegetable-based oils, as these will gum up the mechanism and freeze the gears.
Blenders typically don’t get serviced, as they have sealed upper bearings. Challenges may arise with the bowl’s cutter assembly. Lacking a tight seal in this area, liquid can seep into the bearings and motor, causing big issues and necessitating a costly repair. If the cutter makes an unusual noise, abnormal vibrations, it does not work up to speed or the blender leaks out of the bottom, it needs servicing.
The most common operating mistake users make is overloading the blender, which can cause product spills. Also, misuse of covers or improper lids can make a mess and create big problems, especially with sticky syrups. Never turn on a blender with utensils inside. In addition, do not use ice tongs to turn blender knobs, and do not utilize spoons to push buttons.
Blenders typically have a service life ranging from 10 to 15 years for heavy-duty models. Because blenders are not a pricey piece of equipment, if there is a major failure, replacement is recommended.
