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.

Why does my dehumidifer not work?

If it is not running because it thinks the bucket is full even when it isn't, the problem is that the float is broken or jammed. A replacement is no longer available, but you can find the small switch and tape it so it always stays on. It won't shut off when the bucket is full, but it will run. This assumes all the other panel lights come on properly - you didn't provide much detail about what works and what doesn't work.

Full light is on and won't turn off

There is a float in the back, make sure it is dropping all the way. If the rear tank isn't fully inserted it will also prevent the full indicator from resetting. Occasionally hard water deposits will build up, and it's usually just a matter of cycling the float up and down by hand a few times till it loosens up.

Dehumidifier stopped working because "water bucket full" indicator light stays on, although there is no water in bucket.

In the water bucket is a float assm. scale forms on the assm. and causes it to stick. Remove the float assm. and carefully remove the scale. Should start working again once done. If not you may have to replace it.

I have a delonghi des 14 dehumidifier. Usually it goes into pause mode for 3 mins when you first turn it on with the yellow light on and then starts dehumidifieing.It now stays in the pause mode forever...

Just fixed this problem with my DES14. Its a fault with the circuit board inside the machine and is very easy to fix, even for a novice. Here is how to do it:

1) Open up the machine by removing the screws in the case. (Make sure it is unplugged!)

2) Locate the circuit board on the side of the unit.

3) At this point you have two options. If you want a unit with full functionality you need to buy a replacement circuit board. I found one on MasterSpares ( It costs about 30 pounds. Simply remove the old board and replace it.

4) If you want a working unit for no extra cost (but without the functionality of the humidistat) then remove the rectangular white connector from the circuit board which has red,blue,white and yellow wires entering it. Add an extra wire between the central white wire and the red wire that is adjacent to the yellow. (see photo).

5) Re-assemble the unit. If you have opted for the free option the unit will work when you plug it in and switch it on but will no longer cut in and out with different humidities (or have the annoying warm up period). Thankfully the water overflow cut-out will still work.

Hope it works for you! Feel free to ask if you are confused!

The bucket full light stays on while it is empty. the humidity control doesn't change. the unit is not going on.

There should be a switch that is activated by a float lever that if tripped will make the bucket full light stay on, and will prevent the unit from going on.

If this light is on when the bucket is empty, maybe try to jiggle the float lever, or investigate why the switch is activated when the bucket is empty.

Good luck on this repair.

Full light stays on even though the unit is empty.cant turn unit off/on with button while full light is on.

There may be a little rod of lever which is pressed by the float in the bucket when it is full - I suspect that it may be jammed in the "up" or "full" position.

If you can see it and pull it down to its normal position the machine should start again.
Hope this helps, but if not let me know what you find. Cheers, D.

Maytag electronic dehumidifiers full light stays on

Take out the bucket and locate the "full" switch in the upper right of the area where the bucket slides in. With the unit on, try pushing it in and see if the "full" light goes off.
If so, that switch is fine - if not try to adjust if and replace it if required. Those are generally micro-switches and firms like Radio Shack would have if your appliance parts dealer does not.
