Always follow basic safety precautions when using your dehydrator. Read all instructions.
General Safety

  • Do not touch hot surfaces.
  • Do not immerse cord, plug, or base in water or other liquid.
  • Closely supervise children near the dehydrator.
  • Unplug when not in use, and before cleaning. Allow to cool before putting on or taking off parts.
  • Do not use dehydrator if it is damaged, not working, or if the cord or plug is damaged. Contact Customer Support (page 14).
  • Using third-party parts or accessories may cause injuries.
  • Do not use outdoors.
  • Do not place on a stove, near gas or electric burners, or in a heated oven.
  • Be extremely cautious when moving the dehydrator if it contains hot liquids, and when removing trays if they contain hot liquids.
  • Do not clean base with metal scouring pads. Metal fragments can break off the pad and touch electrical parts, creating a risk of electric shock.

Power & Cord

  • Do not let cord (or any extension cord) hang over the edge of a table or counter, or touch hot surfaces.
  • This dehydrator has a polarized plug (one prong is wider than the other), which fits into a polarized outlet one way. If the plug does not fit, reverse the plug. If it still does not fit, do not use the plug in that outlet. Do not alter the plug in any way.
  • This dehydrator uses a short power-supply cord to reduce the risk of entangling or tripping. Use extension cords with care.
  • The marked electrical rating of an extension cord should be at least as high as the rating of the dehydrator (page 3).

Your Cosori Dehydrator features an automatic fan, which circulates warm air to evenly dry food. Dried foods are a great treat to snack on because they keep almost all their nutritional value and flavor. Dehydrating is the perfect way to preserve snacks, fruit, vegetables, bread, and even flowers.

  • To start or stop the dehydrator, press START/STOP.
  • To change the temperature, press TEMP/TIME once, then press + or –
  • To change the time, press TEMP/TIME a second time, then press + or –


  • To turn sounds on/off, wait for the display to show “–:–”, then press and hold + for 5 seconds until the dehydrator beeps 1 time.


  1. Remove all packaging from your dehydrator and its accessories. Make sure all package contents are included (see page 3).
  2. Clean the base and trays with a moistened cloth.
    Note: The trays can be washed in the top rack of a dishwasher only if you remove them before the drying cycle starts. Do not wash the base in a dishwasher. Do not immerse the base in water.
  3. Place the dehydrator base on a solid, level surface. Plug in. Stack the drying trays on top of the base.
  4. Run the dehydrator for 30 minutes at any temperature, without adding any food. Make sure that the room has sufficient ventilation, in case the dehydrator produces any smoke or smells. This is normal.
  5. Rinse the trays in water. Dry all parts.

Note: You only need to do this the first time you use the dehydrator.



  • Place food on trays. The trays can hold up to 1.1 lb (0.5 kg) of food. Place food on the bottom tray first, and use the top tray last. Be careful not to overload the trays.

Note: The trays can be rotated to provide more spacing between each tray.
Note: Use the dehydrator in a warm, dry room. Depending on humidity in the air and moisture in the food, dehydration time may vary.


  • Plug in. The dehydrator will beep, and the display will show “88:88”. The dehydrator will switch to standby mode after 3 seconds, and the display will show “–:–”.
  • Press TEMP/TIME to choose temperature. The temperature will blink on the display, and the + and – buttons will light up. Use + or – to change the temperature (95°—165°F).
    Note: Temperature changes in 1°F increments. Press and hold + or – to change the temperature rapidly.
  • Press TEMP/TIME again to choose time. The time will blink on the display, and the + and – buttons will light up. Use + or – to change the time (0:30–48:00).
    Note: Time changes in 30 minute increments. Press and hold + or – to change the time rapidly.
  • Press START/STOP to start dehydrating. The dehydrator will start heating. START/STOP will stay lit, and the other buttons will turn off. Temperature and time will cycle on the display every 3 seconds.
    Note: If you press START/STOP again to stop dehydration, the timer countdown will reset and the dehydrator will go into standby mode.
  • Optionally, you can change the time and temperature at any time by pressing TEMP/TIME.
  • When the timer finishes, the display will show “End” and heat will turn off. The dehydrator will beep 5 times, and the fan will continue running for 5 seconds before stopping.
    Note: The dehydrator will always remember your previous temperature and time settings.


  1. Unplug the dehydrator and allow it to cool before cleaning.
  2. If you used a recipe that left traces of liquid or other residue, use paper towels to wipe down the trays before cleaning.
  3. Soak trays in hot soapy water for easy removal of food residue.
  4. Use a soft brush to clean the trays.
    Note: The trays can be washed in the top rack of a dishwasher only if you remove them before the drying cycle starts. Do not wash the base in a dishwasher. Do not immerse the base in water.
  5. Clean the surface of the dehydrator base with a damp cloth.
  6. Dry all parts before storing or using the dehydrator.
  7. When storing, turn the base upside down and wrap the cord around the center of the base. Secure the cord under the clips.
  8. Set the base back upright and stack the trays on top of the dehydrator as normal.
