Flush control does not respond
Note whether a button, lever or sensor feels loose, sticks or produces no normal flush action.
This page covers toilet working parts: the flush control, cistern filling and water that continues to run. If waste water rises or drains slowly, see Blocked Toilet.

Note whether a button, lever or sensor feels loose, sticks or produces no normal flush action.
Listen for filling, note the cistern water level only where it can be viewed safely, and avoid forcing a control.
Record whether water continues into the pan, the cistern keeps filling or the sound stops after a while.
If waste water rises, stays high or drains slowly, see Blocked Toilet. If the flush mechanism, refill or continuous running is the issue, this page is the best place to start.
Add the control type, cistern sound and visible water movement so the repair enquiry stays distinct from drainage.
