Says the tank is full but it is empty? - Maytag M7DH45B2A Dehumidifier

Sounds like the float valve inside tank may be stuck in closed position. Calcium buildup is very common. Good luck Juliana. Unplug and empty tank of any water and look for the float valve it should be near top of tank. Use a small bucket and mix vinegar and water and brush. Scrub that valve. Clean it up

The full light normally comes on when the tank is full. Emptying the tank and re-installing the tank should allow the system to reset. However, if the tank isn't pushed in all the way... the full switch and indicator light will be fooled into reporting a full condition. My suggestion is, first pull out the tank, look at the float and the tank full switch. Become familiar with these two items and confident that 1) the float is not stuck in the up position; 2) the tank full switch that the float is supposed to actuate will toggle (press your finger against it and let it return.) After this exercise make sure the tank is seated all the way in place. If your issue is mechanical, its easier to fix than if it's electrical, and if it is electronic... (just pray that it isn't).

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.

Hi,

The tank may be full. Your dehumidifier has a safety device that turns off the dehumidifier when the water tank is full. Usually the tank itself either presses against a switch or there's a device connected to the tank that triggers a switch when the tank is in place and full.

If you've emptied the tank and the unit still stops running after a min, inspect the place where the tank rests to see if there's a switch or mechanism that's not being activated. You may be able to turn it on with a simple flick of your finger.

Take care.

I thnk your tank is askew. Adjust the osition of the tank until the light goes off ...
