The E3 Code, indicates that the air intake filter needs to be removed and cleaned. Be sure the unit is OFF and unplugged before removing the filter. Filter cleaning should be performed at least once every two weeks, as part of Routine Maintenance.

all this info is in the manual. Either you threw it away or are a person who does not like to read.

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.

Are you worried as to why there is no Water in the Water Tank/Bucket at all?

Well, a few operational basics must be understood by you please.
For the unit to remove moisture from the air and draw water into the bucket/tank, the set relative humidity (%RH) must be below the current or ambient room relative humidity.

Attempt to lower or reduce the setting you have to a lower value and it should start collecting water in the tank.

Hope this helps

Did you punch out (or cut) the plug that the hose connects to? If not, its blocking the water from draining to the hose.

Please rate 4 stars if this is helpful. Thanks and good luck!

It's basically an air conditioner so if the fan is running---the condenser not plugged up via rats nest---lint----the float switch working---if possible tip over switch working----the system maybe low on refrigerant

The normal operating temperature is above 65 F. Much below unless specially designed for low temperature they will freeze up.
They have a frost detector and will defrost but it is very inefficient and not practical. My experience they eventually form a block of ice on the coils. They heat the room in the process so in a moderate area they can raise the temperature and provide needed circulation.

In the past where the temperature is cool I have faced the output into a corner, raised it off the floor and once the unit got started the heat created from the unit kept the air warm enough to avoid freezing up the coils.

Always check for recalls. Some models have had problems and have been recalled. See the link below.

if your unit is old enough to "not" have a gfci on the plug that goes in wall then im not aware it has any fuse inside it that could go bad , instead these rely on the homes proper electrical ckts to provide fuse/breaker functions that keep a fire from resulting if appliance overloads , now as for reasons of overloads these are many ! can be anything from water in the wrong place to a damaged motor inside

ck your water pump and hoses , the light is telling you it has sensed a problem

id be inclined to think that for some reason the pump is taking too long to pump tank out (or it thinks it is ) this would cause the fault you describe and the safety control shuts pump off for fear of a problem

Sounds like the plumbing is obstructed somewhere, try looking upstream as well as downstream of the pump. A very small piece of crud can cause a clot or embolism in the narrow channel. You might try blowing out the system with compressed air, but beware of getting showered with dehumidifier crud!
