Unit wont turn on,,, water full light flashing

without the model number I cant be 100% sure , but due to your description of the last thing u did , Id say the light is flashing indicating that the water catch bucket is not installed correctly back as it was before , most units have a safety that wont allow a unit to operate unless the water catch bucket is installed and M/T as this would allow it to dump water to the floor if it were not

if the red light is flashing this means theres a fault , most common fault on these are water catch bucket is full or not seated back correctly

red lights on dehumidifiers almost always indicate a full water catch bucket , this does not allways mean it's actually full of water , the machine thinks it is , some thing has gone ary with the level sensor in bucket , these most times are a simple float switch, that can get knocked out of position when one is emptying the bucket , also this same float switch also allows machine to know there's a bucket in place to catch water , sometimes bucket is not in correct place to catch water so machine wont start

cont button just means continuous run mode . the power light is lit , the full light is out . try reseating the water catch bucket a few times , most machines have a safety that wont allow the thing to operate if bucket isn't just perfect in its slot (you don't want water on your floor )

if water full light stays on the compressor wont start and remove water from air , investigate why light stays on ? is bucket really full? is sensor knocked out of its fragile holder ? is bucket all the way inside machine so that sensor is connected ?

Usually, when the red water full light glows, it means that the water collection bucket is full & needs to be removed and emptied. Once that's done and the bucket is reinstalled properly, the red light will go out and the unit will turn back ON.

Hi, Sounds like the circuit board...they often will just do that...IF you can get one it will be half the cost of a new unit...
There are many reasons why a dehumidifier willnot work or collect water.
Here is a tip that I wrote to help people to figure out what is going wrongwith their dehumidifier

Dehumidifier is running but no water is in bucket

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 doesn't run, 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.

An automatic overflow switch and Container “Full” indicator light are provided to turn the
dehumidifier off before the container overflows. When the indicator light on the control panel
glows, the water container must be emptied. If the light remains on and the dehumidifier does
not begin to operate make sure the float is attached to the water container.


When the condensate water container is full, the indicator lights up.
1. Turn the power off before removing container. Wait 3 minutes for
any remaining water to drain into the condensate container.
2. Tilt the container forward then lift carefully by the handle.
3. Empty and gently re-insert the container.
Important:This water is not suitable for drinking.

Please rate and god bless:)

I have a 45 pint. I have to slide the bucket in and out of the unit multiple times. Make sure to wait a few seconds after each time to see if it will recognize no water (sometimes the red light comes on, but then changes it mind). Also, I've found that leaving the bucket a little crooked will make it respond. It sucks, I know. Mine is only a year old too. Should not be a problem like this!
