What to do if 'F' appears on my Hisense I6421C Hob display?

If the error indicator "F" appears and does not disappear, disconnect the Hisense hob from the power mains for a few minutes by undoing the fuse or switching off the main switch. Then, reconnect the hob to the power mains and switch it on using the main switch key.
