IBC SFC-1 F028 — Reset button fault
F028
The controller detects the reset (wrench) button being activated unintentionally — for example pressed continuously by something leaning on the panel or during cleaning. It flags the input as suspect.

Why a code is not a diagnosis
The cause is usually physical (something pressing the button) or a failing control panel. The code does not distinguish.
Safe things to observe
- Check whether anything is leaning against the control panel or if the button is stuck.
- If nothing is touching the panel and the code persists, call a technician.
Do not
- Do not force or pry the reset button.
How professional service helps
- A technician checks the reset button for unintended operation and replaces the control module if the button input is faulty.
