is there a solution for the E3 code?

Float is stuck

Dehumidifiers aren't supposed to cool your house. If anything they generate heat. How it works is, it has cooling coils that it draws air across, which causes the moisture to condense, and be captured. However the heat extracted from the air has to go somewhere, so it just blows out the other side. If you want cool, buy an air conditioner.

There are 5 basic, but solvable reasons for what you described. Please pay particular attention to numbers 1& 2..

1. The humidity extraction level is set to HIGH. Lower it to 32-35%.

2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.

3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.

4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.

5. Ambient air temperature at floor level is between 40 - 60 degrees.
dehumidifiers do not work well between those temperatures
(Unless, you have a Low Temp Unit). This applies mainly to
where the air temperature at floor level is colder than at shoulder level
in basement applications. Raising the unit up off the floor,
onto a sturdy table, counter top, etc, that can handle the weight
of the unit, plus a full tank of water, will usually resolve this
problem.

If none of the above solves the problem, it may be a case of the compressor needs to be recharged with refrigerant gas or that the humidity condenser sensor has failed. These things usually occur in units that are 5 years old or older. It's rare in a unit younger than that. But, it can happen.

I hope this helps you to further troubleshoot & solve the problem. Thanks for choosing FixYa.

Did you solve this problem? Mine is only 2 years old and is having the same problem.

The drain tube that drains the water into the bucket is clogged and needs to be cleared.

To do this, you will need at least an 18" long plastic Zip Tie or something similar. (But, NO wire coat hangers) that will fit into the drain tube or hole. Carefully work the Zip Tie into the hole or tube and gently push it forward. You will reach a bend in the tubing, but you will have to gingerly work past this bend. Once the Zip Tie bottoms out or you run out of Zip Tie. slowly pull it back out while rotating it. This will help breakup the clog. Once you start reaching the end of the inserted Zip Tie, be prepared for some water to follow.

The above procedure should solve the problem. Please let me know. Thanks.

there should be a pump somewhere near the pan, the pickup for the pump must go into the drain pan somewhere if you can find the pump, the nipple the hose attches to is close by please rate

it usually means either a dirty air filter or low freon
