Likely your printer is not able to reach and hold the requested 225°C

While this should theoretically be possible, I've read several times about stock hardware not being able to reach the max. temperature. I have replaced the wiring harness (for different reasons) with a slightly greater diameter and also use a different power supply, so I do not have any issues with stable >230°C. Before it sometimes hit the same error when there was unwanted air or the room was slightly colder than usual.
