Code-specific guidance for F3
A Cooktops & Rangetops that stops normal operation while showing F3 deserves a careful look before you rely on it for a large meal or a full dish load. Use the manual’s safe steps, then reach out if the code persists.
For dishwashers, note whether water remains in the tub, whether the drain pump runs, and whether the door latch feels solid before repeated resets.
