Troubleshooting
This section addresses common issues you might encounter with your LAUFEN Pro Wash-Down WC.
| Problem | Possible Cause | Solution |
|---|---|---|
| Toilet not flushing properly or weak flush. | Low water level in cistern, blocked rim holes, or issue with flush mechanism. | Check water level in the concealed cistern. Clean rim holes if blocked. Consult your cistern's manual for flush mechanism adjustments. |
| Water leaking from the base of the toilet. | Loose mounting bolts, faulty wax ring/seal, or crack in ceramic. | Tighten mounting bolts (do not overtighten). If leak persists, the seal may need replacement. Inspect ceramic for damage. Contact a plumber if necessary. |
| Slow drainage or blockages. | Partial blockage in the waste pipe or toilet trap. | Use a plunger. Avoid flushing non-biodegradable items. If severe, a plumber may need to clear the blockage. |
