Troubleshooting
Cistern not filling with water
Check that the main water supply is turned on and that the isolation valve to the cistern is open. Ensure the inlet valve is not obstructed.
Water continuously runs into the bowl
The outlet valve seal may be faulty or misaligned. Check the flush mechanism and seal for debris or damage. Adjust or replace the seal if necessary.
Low water pressure or slow filling
Verify the water supply pressure. Check for any kinks or blockages in the water supply pipe. Ensure the inlet valve's filter is clean.
Flush buttons not working correctly
Ensure the flush buttons are correctly linked to the flushing mechanism. Check for obstructions or disconnections between the flushplate and the cistern.
Frame seems unstable
Confirm that the frame has been correctly installed and securely fixed to both the wall and the floor according to the manufacturer's instructions. Re-tighten fixings if necessary.
