Error code 14 and 15 with the flashing red wrench! I was able to first fix the problem with a simple reset, shown in the beginning. Eventually, that didn't work anymore. The wires bend sharply going into the connections under the digital display. Straightening the wires and taping the connections seems to fix the problem. (paid link)
