Why i can not power on the unit?

Before jumping to any conclusions, remove the water collection bucket and check the inside of the bucket for a float valve (if yours is so equipped). It may be stuck in the UP position, which will not allow the unit to start. If it is, jiggle the arm of the valve to make it return to the down position.
Reinstall the bucket "squarely" into the bucket holder, making sure that the back of the bucket makes good contact with the bucket safety removal switch. This is important, because if it doesn't, the unit will not start.

If all of the above fails, check the outlet the unit is plugged into, to be sure the outlet still has power. If it doesn't check your home's circuit breaker panel for a tripped circuit breaker. If you find one, unplug the unit, before resetting the breaker. Aslo, check the outlet for a loose wire connection.

Hope this helps you to troubleshoot and solve the problem. Thanks for choosing FixYa.

Make sure the bucket is installed properly. It you are CERTAIN it is installed properly and you still get no power to the unit (you said you definitely have power at the wall outlet) return it to the store and either get it demo'd or replaced. Definitely rule out the wall outlet by testig with a light or a radio before you load the unit into the car.

Any more than what I have suggested may void any warranty you may be entitled to. Don"t wait.

Thank you for your question @ FixYa.com

To troubleshoot the problem: First start with the wall outlet. Is there still power to it? If not a circuit breaker in your homes breaker panel may have tripped. Is there a lose wire connection in the outlet or is the outlet damaged inside? If all of these things check out OK, try plugging the unit into another outlet that's on a different circuit.

Other causes:

The bucket is full. Unit shouts off completely when this occurs.

The bucket is not installed properly. Remve bucket and reinstall it "squarely" from top to bottom
into the bucket holder.

If the ambient room temperature is 112 degrees F or lower than 32 degrees F, the unit will shout down to protect the compressor. Wait 3 minutes and then restart the unit.

If all of the above troubleshooting fails to resolve the problem. Call Haier Customer Service

Try resetting the bucket, making sure that it is set properly and triggers the safety lever/switch. If that doesn't solve the problem. Turn the Master ON/OFF Switch to OFF, unplug the unit from the wall outlet and wait 12-15 minutes. Plug the unit back in and turn the Master ON/OFF Switch to ON. If the bucket is installed properly, the unit should revert back to the original factory settings.

Hope this helps solve the problem.

Check the outlet that the unit is plugged into, to be sure that it's still has power. If it doesn't, a circuit breaker for that outlet may have tripped. Or the outlet receptacle may have a loose wire. Try plugging the unit into another outlet that is not on the same circuit, as the one it's currently plugged into.

To figure out what Code F2 is, I took a look at the Owners Manual for the Model # AD70USS, Strangely, the Owners Manual doesn't list an F2 Code or any codes for that matter. Because that model number humidifier, does not have an LED screen.

Never the less, to reset your unit using an alternate method. Turn the Master ON/OFF Switch to OFF and unplug the unit from the wall outlet. Wait 12 - 15 minutes before plugging it back in. Then turn the Master ON/OFF Switch to ON and the dehumidifier should have reset itself. If it doesn't check the positioning of the water bucket, to make sure it's contacting the safety switch. Eventhough, you're using a drain home, it's still important.

Hope this helps you solve the problem.

Try reinserting the bucket, making sure that it's positioned properly. So that the safety switch is engaged. If that still doesn't solve the problem. Turn the MASTER ON/OFF Switch to OFF and unplug the unit from the wall outlet. Wait 12 - 15 minutes and plug the unit back in. Turn the MASTER ON/OFF Switch to ON and hopefully, if the bucket is positioned properly, the unit will have reset itself.

Hope this helps you to solve the problem. Please let me know.

First, check the outlet that it's plugged into, to make sure that there's still power to the outlet. If there isn't, then the circuit breaker for that outlet has been tripped, in your home's circuit breaker panel. Leave the dehumidifier unplugged and reset the circuit breaker. If it trips again, without the dehumidifier unplugged, then the outlet is at fault. Perhaps there's a loose wire connection or the interior of the outlet is cracked.

If it didn't trip without the dehumidifier plugged in, plug the unit it in,. But, before you do, make sure the dehumidifier's Master ON/OFF Switch is OFF. Once it's plugged in, turn the Master ON/OFF Switch to ON and set your controls. If it runs now, GREAT! If it trips the circuit breaker again, there's either a short in the power cord or an internal electrical short. Which will require extensive troubleshooting to find.

Hope this helps you solve the problem. Please let me know. Thanks.

Hopefully, it's not a problem inside the unit that's causing the circuit breaker to trip. Is there another electrical appliance plugged into the same outlet or on that circuit that is ON and draws 15 amps of power? If so, that's the problem. If that's not the case, turn the circuit breaker OFF and remove the outlet cover, so you can inspect the receptacle and it's wiring. A loose wiring connection or a broken or cracked receptacle could be the issue. If you don't find any damage reassemble the outlet and turn the circuit breaker back ON. Instead of plugging in the dehumidifier, plug in a lamp or something similar and turn it ON. Leave it on for more than 5 minutes to see if the circuit breaker trips again. If it does, you'll know the problem is either with the outlet receptacle or the circuit breaker. If doesn't, plug in the dehumidifier (Make sure the Master ON/OFF Switch on the unit is in the OFF position, before plugging it in. Then turn the Master ON/OFF Switch to ON and set your controls. If the circuit breaker trips again, the problem is in the dehumidifier. You will need to call Whirlpool Customer Care, as it's an internal electrical issue.

I hope what information I have provided to you, will help you trouble shoot and solve the problem.

either try a different outlet to see if the G.F.C.I. is bad on this outlet or if the dehumidifier trips on another line it could be the units motor start capacitor that shorted or the compressor is bad
