Hi, welcome to Just Answer. My name is ***** ***** I look forward to helping you! Turn the power off at the mains for at least 4 hours. That will reset the electronics. If the error comes back, the power interruption likely damaged the electronic control. Let me know what happens after the extended power cycle.
