I own 2 Haier air conditioners. Same model number, purchased at the same time. Plugged them in yesterday and one is collecting water in the bottom and shuts off. The only way to get it to come back on is to use drain plug and drain out water. Whats causing this and whats the solution?? Help!!

Condensation occurs when warm, humid air is pulled across a cold fins of an air conditioner and blown out the front as cool, dry air.

What is happening with your air conditioner sounds to be normal operation - here's why:

The condensate usually drips onto the ground from traditional window air conditioner units or through a pipe to the ground from remote air handlers of split systems. Since yours has no place to drain away into soil or waste pipe, it is collected in a compartment that must be emptied, just like a dehumidifier. When the compartment is full, the unit shuts off - otherwise the compartment would overflow on the the flooring or carpet. This could be a very expensive repair if hardwood floors were damaged or carpeting were to become moldy. Even more so if the the space under yours were finished - like an apartment building or if you used this on the second floor of your home - and damage to the ceiling below were damaged.

You could operate the device if it were connected by a hose to a drain at or below the bottom of the connection point (a floor drain, shower drain, etc.) or if the unit were placed on a counter top and allowed to drain into a sink or other drain / waste pipe below the the hose connection point. The hose must not get higher than the connection point at the drain plug on the air conditioner to work properly.

I hope this helps and good luck.
