My CUBE is showing an Error, what should I do?

If your CUBE Control Unit is displaying an F1 Error Code:

  1. Turn off the Cube.
  2. Unplug the Cube and then wait a minute before plugging back into the Cube. ( Note:This can be done from the base of the Cube or from the outlet.)
  3. Make sure that the Cube has at least 18" of space on all sides to allow for proper ventilation. 
  4. Feel for air blowing out of the Cube to be sure the fan is working.  
  5. If this does not resolve the issue, perform a factory reset on the Cube by turning it off again. Next hold down the power button on until the display flashes "888". ( Note: You will need to re-sync your remote to your Cube if this is done. Please consult your user's manual for the steps on how to complete this process.)
  6. If the issue persists, your Cube may need to be serviced or replaced. Find the serial number on your Cube (located on the barcode sticker on the bottom of your Cube). Please make sure to enter this on the form when reaching out to Customer Experience. 

If your CUBE Control Unit is displaying an F2 Error Code:

  1. Make sure that the unit has at least 18" of space on all sides to allow for proper ventilation. 
  2. Unplug the unit from its power source for a few minutes to allow the unit to totally cool down.
  3. Plug the unit back in and try running it. If the issue persists you will need to complete an internal reset on the unit.
    • Unplug the unit again and confirm that the cap of the reservoir is securely screwed in. 
    • Turn the unit so that you can see the bottom, and locate the hole below the sticker that begins with "For household use only"
    • Using a thin long tool, such as a screwdriver, pen, or pencil, press the button found recessed behind this hole for 5 seconds. ( Note: This is a flat button and will not produce a clicking sound but if you go straight into the hole you will land directly on it. )
  4. After completing these steps you should be able to set your system back up and run it without issue. If the issue persists, your Cube may need to be serviced or replaced. Find the serial number on your Cube (located on the barcode sticker on the bottom of your Cube). Please make sure to enter this on the form when reaching out to Customer Experience.

  3. Lift the unit and shake it up and down, forward and backwards and side to side with moderate power.
