# Maintenance and troubleshooting for Totem Digital smart bins

> Cleaning, periodic checks and fixes for common smart waste bin problems: the door does not open, the battery does not charge, or the indicator stays red.

Regular maintenance keeps Totem Digital smart waste bins hygienic and working. This page covers cleaning, periodic checks and fixes for the most common problems.

## Cleaning

* Clean the housing with a damp cloth and neutral detergent. Do not use solvents, abrasives or pressure washers.
* Wash and disinfect the inner liners and the inside of the compartments regularly.
* Wipe the solar panel with a soft cloth and water, without pressing on the surface. Dust, leaves and snow reduce charging.
* Clean the presence sensor window so the door opens correctly.

## Periodic checks

| Frequency | What to check |
| - | - |
| Every emptying | The bag is fitted correctly, the door closes fully |
| Monthly | The solar panel is clean and unshaded, the sensor works, the LED lighting turns on |
| Every 6 months | Floor anchoring, paint and seals, door hinges |
| Yearly | Technical check of the battery and electrical system by authorized staff |

<Tip>
  In winter, clear snow from the solar panel. Short, cloudy days can reduce autonomy, especially on models with a smaller battery.

## Troubleshooting

<AccordionGroup>
  <Accordion title="The door does not open automatically">
    * Check the fill-level indicator. If it is red, the bin is full and the door stays closed until it is emptied.
    * Clean the presence sensor window.
    * Check that nothing is mechanically blocking the door.
    * If the indicators and lighting are off, the battery may be flat (see below).
  </Accordion>

  <Accordion title="The bin is off or the battery drains quickly">
    * Check that the solar panel is clean and not in shade.
    * After a cloudy period, leave the bin in the sun for a few days to recharge.
    * If the problem continues, the battery or panel may need inspection. Contact support.
  </Accordion>

  <Accordion title="The indicator stays red after emptying">
    * Check that the new bag does not cover the level sensor.
    * Remove any leftover waste from the bottom of the compartment.
    * If the indicator does not return to normal, contact support.
  </Accordion>

  <Accordion title="The door opens by itself with nobody there">
    * Check for objects, plants or a constant flow of passers-by in front of the sensor.
    * If possible, turn the bin to reduce false triggers.
  </Accordion>

  <Accordion title="4G data does not reach the monitoring system">
    * Check that the SIM card is active and has a data plan.
    * Check mobile coverage at the location.
  </Accordion>

  <Accordion title="The compactor does not work (WYC-2021-120)">
