Thermostat is showing E 9 error not working

Hi Adilamasham,
Thanks for reaching out. E9 error code means that the thermostat detects a wire in the C terminal but can't complete a power-sharing circuit. Let's check this further.
A few questions: what type of Nest Thermostat do you have? How's your Nest Thermostat wired? What's the power reading of your Nest Thermostat (You can find this information by going to settings > Technical info > Power)?
I'll look forward to your response.
Thanks,
Jennifer
