An E5 error on your Hisense air conditioner could mean a number of different things. In some instances, it can be a sign that the water tank needs to be drained since it is full. With portable air conditioners that employ a condensate tank to collect water created during the chilling process, this is a common issue that might develop. To avoid water overflow, the device will turn off when the tank is full.
