Common Symptoms & Causes
If your InSinkErator Cover Control Plus is experiencing any of the following symptoms, a worn or damaged stopper cover is likely the culprit.
🔨 Pro Tip from Dave
The Cover Control Plus uses a twist-and-lock stopper assembly, and the most common mistake I see is forcing the new cover on without aligning the tabs properly first — this cracks the replacement right out of the box. Look for InSinkErator part number STP-00 or the Cover Control stopper kit, which includes both the cover and the mounting collar. Make sure the disposal is unplugged before you start, since this model’s switch is integrated into the cover itself.
- The stopper cover cracks, chips, or breaks apart during normal use
- The cover no longer sits flush or seals properly over the drain opening
- The stopper cover feels loose and shifts or spins uncontrollably
- Visible warping or discoloration on the surface of the stopper cover
These issues are typically caused by everyday wear and tear, prolonged exposure to heat and moisture, or accidental impact that degrades the stopper cover’s rubber and plastic components over time.

Frequently Asked Questions
Do I need any special tools to replace the stopper cover on my InSinkErator Cover Control Plus?
No special tools are required — the stopper cover typically snaps or twists off by hand. Having a soft cloth nearby to protect the sink finish is helpful.
How do I know if my stopper cover needs replacing rather than just cleaning?
If the cover is cracked, warped, or no longer sits flush over the drain opening, replacement is the better option. Cleaning alone won’t fix physical damage.
Will any stopper cover fit my InSinkErator Cover Control Plus?
No — use only a replacement cover designed specifically for the Cover Control Plus model to ensure a proper fit and seal. Check InSinkErator’s parts list for the correct part number.
