💡 Technical Clarification

Error code O indicates that one of the three sensors for the bin hood is operating intermittently or inconsistently. That said, this code is for reference only and the system should be able to work properly with redundant backup electronics. Otherwise, the issue will be escalated to error code I.

The following steps can be safely disregarded, though are outlined with an intention to eliminate any possible environmental factors underlying this error:

  • Proper seating helps prevent imbalance, wobbling, or tension that could interfere with the bin hood. Please double-check its setup using this short assembly guide: https://youtu.be/bZ3mRNZrMH4.
  • Please make sure there is sufficient clearance for the hood to open, and no nearby obstructions.
  • The hood can be programmed to stay fully upright briefly to prevent premature closure. Try enabling the Keep Upright feature in Popur S7 App → Device Page → Top-right icon for Settings → Dump → Keep upright.
  • The trash bag itself can sometimes interfere. Heavy clumps resting on the bag may pull the hood back—please stretch the bag fully so it reaches the bottom of the bin.
  • If the unit is placed on a plush carpet or thick litter mat, it may tilt slightly and press against the bin, affecting hood movement.

After these checks, plug in the bin hood and power cycle the machine.
