If the lever / rod which is moved by the floating part in the bucket moves up and down OK, but the light stays on, then I would suspect the microswitch which is on the other end of the lever / rod to be faulty. This is a job for someone with electrical training, so don't go there unless you know what you are doing!
Hope this helps you a bit more. Cheers, D.

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.

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.

Full light stays on always

Don't know your model specifically, but most dehumidifiers have a float that shuts the system down when the tank is full. Maybe the float is not going up and down like it should. With the power off and the tank out, see if the float is descending like it should when the tank is out. Popping it up and down a few times might solve the problem.

How do you put floater device back in water tank

It should just snap back into place, inside the small compartment in the top left of the water tank.
When you snap it back into place it should be able to move freely, up and down.

Hope this helps you.

Have hose hooked up but it does not drain. Compartment fills with water and needs dumped manually. Want the hose to work so twice-a-day dumping in basement not needed. Thanks!

You connected a hose to the hose outlet on the catch tank ... right? The tank will not drain even though there are no kinks in the hose and the end is lower than the tank, right? Did you put a hole in the tank before you attached the hose? I will bet not ... and I will not laff at you ... I did the same.

Put a hole in the tank (where the hose attaches), reattach the hose and all will be well.

Thanks for your interest in :-)

Dehumidifer shuts off when tank is only 1/4 filled

Sensor calibration . Make sure you are using the factory bucket, I believe it senses the weight of the bucket and water combined.Check and make sure the platform is not taped for shipping .

Unit collects water but periodically continues running despite full bucket which is flush in unit, what could be causing this it doesn't happen everytime.

there is a floater switch on the machine over the bucket (and sometimes in it). the floater tells the machine that the bucket is full. if the floater is stuck, the machine will assume that the bucket is not yet full, and will continue to run. check that floater switch with the bucket out. you may need to press in the bucket switch so the machine thinks the bucket is in. then lift the floater and see if it stops running. if not, the switch is bad.

Check the point on the tank (Bucket) where the hose connects to. Make sure there is no obstruction at the outlet of the bucket to the hose connection. Next make sure the hose has no kinks or no loops that may trap air to the drain. If necessary for a long run to the place of drainage raise the dehumidifier to a higher level for better drainage.
