Blade does not cut well ¶
Chopping/mixing blade is dull
Blade Sharpener ¶
You may start to notice that sliced/chopped food are not as fine as they once were. If your blade doesn't cut as well as it used to, you may consider a blade sharpener. It can be done by hand using a sharpening stone or by utilizing an aluminum oxide grinding wheel.
Blade Replacement ¶
Another way to get more efficient cutting blades is to replace them entirely. We recommend visiting our blade replacement guide, and you can find some parts and accessories at the Hamilton Beach website.
Device keeps jamming ¶
Food stuck in blades
Food Build Up ¶
Depending on the type of food that is being chopped/mixed the motor may experience increased resistance due to food residue. A common symptom of jamming is slow rotating blades. If possible make sure you are cleaning your mixing blade after each use. Make note that the Food Processor should not be used on grinding grain, coffee beans, spices, frozen meat, dough, or ice.
Buttons not working ¶
Keys are unresponsive
Device Power ¶
Make sure the Hamilton Beach is plugged in correctly. The device must be plugged in order to operate.
Faulty Buttons ¶
When using the center pulse switch, if the device functions at one speed setting while malfunctioning at the other, this is a strong indicator that the switch is damaged and should be replaced. Sometimes sugary substances or food residue can lead to button jamming. Try and keep liquids and food products away from the switch.
