What does E5 Mean on Hisense Air Conditioner? 

Any electronic equipment can malfunction due to various reasons, and most of the time, they will show you an error code to indicate the issue. Accordingly, the problem that is shown by e5 on Hisense portable air conditioner is the water collection tank has become full.

You may wonder why this case occurs because the latest Hisense portable air conditioners come with the feature of fully self-evaporating. So, the AC has the ability to recycle the water gathered by condensation. Therefore, draining is not needed.

So, what is the reason behind it? The climate changes make the water tank full. If there is extreme humidity, the air contains excessive moisture. Thus, the AC itself cannot fully evaporate the moisture. As a result, the water tank becomes full.

When the tank is full, the air conditioner shuts down by itself. Otherwise, the water can overflow from the tank.

Apart from the above-discussed issue caused by the humidity, there may be some other reasons behind this error code.

2. The Evaporator Coil is Frozen – the evaporator coil needs adequate warm air to function properly. Otherwise, it can be frozen. Apart from the low temperature, a lot of contaminants and filthy air filters can cause this issue on the evaporator coil. When the AC is turned off, the melted ice will fill the tank. Whenever you turn the AC on, the machine notices that the water level is high inside the tank, so it will show the error code.
3. The Refrigerant Level is Low – the refrigerant usually remains stable, and so does its level. But sometimes it can leak because of tear or wear. If the level decrease, again, the evaporator coil can be frozen so the error code can appear. Moreover, it is a treat to the capability of cooling air.
