6. Maintenance
Regular cleaning and maintenance will ensure the longevity and hygienic performance of your WC pan.
6.1. Cleaning the Ceramic Pan

- For the CleanOn rimless design, wipe the entire inner surface of the bowl thoroughly.

- Do not use abrasive cleaners or solvents, as they can discolor or damage the plastic.
6.3. General Care

7. Troubleshooting
This section addresses common issues you might encounter with your WC pan.
| Problem | Possible Cause | Solution |
|---|---|---|
| Water continuously runs into the bowl. | Faulty flapper/flush valve seal or fill valve issue. | Inspect and clean the flapper/flush valve seal. Adjust or replace the fill valve if necessary. |
| Weak flush. | Low water level in cistern, clogged rim jets (unlikely with CleanOn), or partial blockage in trap. | Adjust water level in cistern. Check for blockages in the trap or waste pipe. |
