To factory reset the TRADFRI wireless dimmer (ICTC-G-1) press the button 4 times (so the red lights starts blinking). After the blinks you might be willing to rotate the dimmer like you are trying to control your lights. It will prevent the device from going to sleep and ensure successful pairing. In case the dimmer was recognized but no actions seems to be detected, try to restart the zigbee2mqtt. See IKEA TRADFRI wireless dimmer (ICTC-G-1) not pairing.
