Tank-Full light keeps flashing

I used my Haier HDN655E dehumidifier once. Unplugged the cord. Emptied the tank. Put the tank back in. Plugged the cord back in and I get a several beeps with the "Tank-Full" light keep flashing.

I had tried the following:
1) According to the manual, it takes 3 minutes for the 'Tank-Full" to disappear and then it will work. I waited for 15+ mintues and I still the same thing, flashing "Tank-Full" light.
2) I pressed the ON button and waited for 15+ minutes and still same thing, flashing "Tank-Full" light.
3) I pressed every button trying to reset. Same thing, flashing "Tank-Full" light.
4) I adjusted the water level latch thingy and same thing, flashing "Tank-Full" light.
5) I took the unit apart (plastic cover). Inspected the components. All appears in brand new shape. (I only used it once.) Reassembled it and same thing, flashing "Tank-Full" light after plugging it again.

when you "...pressed the on switch and it turned on and then turned off and it won't turn back on...", was this done in rapid succession or was some time allowed between switching? if rapidly, the micro inside "locked-out" the keypad for starting, to prevent compressor damage. if not rapidly, then look inside for a possibly a starting relay...did it used to "click"?

SOURCE: Haier HDN655E unit runs but compressor won't kick in

use a jumper cord and go directly to the compressor to see if it will run. if it don't run, open up the motor box and see if there is a klixon overload inside. this should be normally closed. if it isn't replace it. the klixon is a thermal overload cutout. it usually trips because of high winding temperatures and protects the motor inside. the compressor is a hermetically sealed unit. no, or little freon will cause the motor to overheat.

There is an internal fuse. Take off the outer plastic casing. The fuse is on the bottom of the board on the upper right of the unit. It's a 12 amp fuse. I had the same problem and found the fuse blown.

SOURCE: Haier Dehumidifier stuck on 45

Check the coils at the back of the dehumidifier to see if there is any frost buildup on it. If there is, turn off the machine for a while until the room warms up and melts off the frost. The machine works by condensing the moisture in the air over these coils, so if the coils are frosted over, or are not cold enough, the moisture cannot condense. If the coils are not cold enough, you may want to get it refilled with refrigerant. You will need to take it in for servicing in this case.

Hope that helps! Should you have any further questions, please feel free to post them here.

Hi I have problems with my mitsubishi dehumidifier Oasis Elite MJ-E-142NX-A1 The water tank full light stays on even though the tank is empty. I have emptied the water and replaced the container care

Sounds like your float is stuck in the full position, or the sensor that shows full is stuck on full.
If tank is empty but shows full, problem lies where full signal is coming from.

No lights on control panel. Plug is powered.

Independent of the bucket switch, the control panel should light when the unit is plugged into a powered receptacle and the on/off switch is depressed. The problem is likely the 12 amp. fuse located inside of the unit.

Does not turn on

All dehumidifiers have an interlock to prevent them from running when the tank is out. This is to avoid a mess with not tank for the water to collect in. I would say that your interlock switch is in a position which is telling the machine that there is no tank in the unit. Take the tank back out and look into the space with a flashlight to find the switch. It could be on the bottom or the top. Your operation manual might be helpful in locating the switch. Once you find the switch check it for operation. It should move or depress when the tank is put in. It probably is jammed and you will have to determine whether it can be fixed or you may need to replace it. If it moves freely then it is probably defective and will need to be replaced. Good luck.
