Aoa. Guys I have a dawlance H Zone split which works wonderfully well since last 3 years. Today I cleaned it's filter as routine after getting the FC message. After that, I cleaned the condenser grill with a damp use tooth brush. When I turned the AC on afterwards, it's cooling was perfect but after five minutes it gave me E5 error. Tried to Google it but no solid answer. I have turned it off as a precaution, but can someone please help me in this. Regards
