My des12 red light wont go off although unit is empty of water

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

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

the units self testing and it takes a moment to ck that everything is ok , red light ind. it;s found a problem , ck simple things first , empty bucket, ck float sensor inside bucket ck for Level (gravity) ck filter for cleaning and reset filter alarm if present , then move on to more difficult things like is something wrong with cooling fan or did water get inside and dammage something

Should have bought a Vicks! My red light goes OFF! No it easy. Unplug the unit for 10 minutes. Fill up with water while waiting. Turn it on! If the red light still come on then you gots scale or build up inside that needs to cleaned out. Follow or call manufacture on how to clean unit...

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.

Actually, the fan shouldn't be working if the water bucket is not installed properly. So, I believe it's more of a case of the electronic controls need to be reset.

To accomplish this, turn the Master ON/OFF Switch to OFF and unplug the unit for 15 minutes.
After the time as elapsed, plug the unit in and turn the Master ON/OFF Switch to ON. The Bucket Full light should not, now be ON. And the unit can function as it should, after you reset the controls for maximum humidity extraction (32 - 35%).

Hope this helped you troubleshoot and solve the problem. Please let me know. Thanks.

The model number you listed did not reveal anything. However, the link below is a link to a Danby model, that had a model number closest to yous. Most of the units have the same parts and function. Click n the literature tab and the Owners Manual will come up.

Hope this helps you. Please let me know.

Did you just empty the container? We have one that sometimes you have to slam it back in to get the red light off. Try to take it out and put it back in. Power it off even if you have to unplug it.

If the unit is titled forward at all, the "full bucket" "trip switch" will not trigger off as it should. Be sure the unit is on a flat, level surface, or leaning backward slightly--this also aids drainage through the drain tube, if that's your set-up.

it should be a float whitch..somewhere around that bucket....take a look, sounds like it stuck ..and tripping whole system
