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

SOURCE: DeLonghi 50 Pint dehumidifier DE 500P won't turn back on

If it is not responding when you try to activate the shutoff button and are still not recieving an acknowledgement that the bucket is full you may hav a defective shutoff button. Try contacting the Manufacturer and see if you can purchase just the button. This i a common part and the price is usually reasonable. If you feel very technical inclined you can remove the button and touch the 2 wires together simulating a closed contact. The dehumidifier should now acknowledge the bucket is full. If you recieve the notification then the button is bad. If you found this solution helpful please rate it.

Thanks - Tech101

SOURCE: 'bucket full' light on, but bucket empty

There is likely a switch operated by a float to turn that light on and turn off the compressor, sometimes manufactures use a rubber "O" ring on the float shaft and they can slip. take the cover off the pump and check the float or in some cases one of two floats are used. Once float turns the pump on and off and the second float shuts OFF the compressor and turns ON the full reservior light.

SOURCE: the P1 light is on

P1 means the evaporator coils are freezing up.The P1 error is related to low airflow.This can be due to clogged or dirty filter.Take the filter out and clean it, if its dirty the dehumidifier can frost up due to the lack of air flow and will not work correctly.In some cases if the filter is too old then it has to be replaced.This should help.Thanks.Helpmech.
