No dehumidifer does not hot air gushing out the top.it is normal.

Normally dehumidifiers collect the water that they have pulled from the air in the tank. Therfore no hose is required. You just have to empty the tank when full. Most models have a float switch which shuts off the machine when the tank is full. Hoses to get rid of water are normally only fitted on industrial machines.

Yes its very normal.

This may be caused by running the unit in continuous mode, rather than timed mode. The heat is generally is generated when the defrost mode cycles on, to defrost the cooling coils. This happens more frequently, if the air space around the unit is obstructed or it's operating in a temperature range of 40 to 60 F. Cleaning the air intake filter at least once a week, can help solve this problem, too.

Maintain a minimum of 12" free air space around all sides of the dehumidifier. Use a timed mode rather than a continuous mode. Make sure the room is within the proper operating temperature range and clean the air intake filter weekly.

Hope this helped you troubleshoot and solve the problem.

Hi,
There are many reasons why a dehumidifier willnot work or collect water.
Here is a tip that I wrote to help people to figure out what is going wrongwith their dehumidifier

sounds like your evaporator coil is dirty its the coil where the air goes in

Againg, if theres no moister in the air it wont remove water. if you feel the location for exmaple a basment feels cool when entering , then mosuet exist. dehumidifer will make any location warm when removing the coolnest in the air. within summer hot months it will collect more water than in the winter months. if it does feel cool and machine dont remove the water. call a repair person.

MOst likely the room the dehumidifier is operating is is too cold for proper dehumidification to take place. Try warming up the room and I believe then your dehumidifier will work fine.

That's pretty normal. Most of these portable units blow quite a bit of heat.

sounds like a sealed system issue it has a 5 yr. warrenty on the sealed system, cost to repair might mean an new one instead
