Summary
If you have a Cooper and Hunter mini split with an EE error code, there is a problem with the water pump.

Water pumps are often used in basements or similar when the condenser water can not gravity drip to an outside location.

These small units are called condensate pumps and usually work without any issues.

A condensate pump will have a small holding container that water drips into. When the start level reaches a certain point, the float will activate a switch that turns on the water pump.

When the water falls to a low level, the float will activate a switch that turns off the water pump.

If they do go bad often, a line is clogged with debris which blocks the water from being pumped out or dripped into the holding container.

Wiring can also be a failure point with a loose connection causing an issue.

Condensate pumps can also fail and need to be replaced.
