Our dehumidifier had an error code e1, felt warm, and wasn't taking the humidity out of our basement air. I removed the cover to the filter area (5 screws) and found a wall of ice. I used a hairdryer to melt part of it away. It wraps around the tubing toward the back. How do I fix this? I really need the dehumidifier to get the musty dampness out of the basement. Thanks!

Re: Delonghi dh400p dehumidifier error e1 with ice
The condensation drain is being blocked from draining....kinked hose or lint...the symptom is cold air being blown across. If you left it unplugged...defrosted and works...check the drain on maintenance schdule

I bought a cheap digital humidistat at Walmart to keep an eye on the humidity in my basement. I hung it on the wall not too near my dehumidifier. I have found that the settings on the dehumidifier are misleading, but I found a setting that keeps my humidity between 40% and 55% (at around 70 degrees), as measured by the humidistat.
First, try cleaning out your filter if you haven't already. It gets angry if it can't get any air.
If not, I don't know how brave you are, but I ripped mine apart to fix the problem. I took off the panel with the filter (5 screws) and you can see a collection tray with another little collection gutter under that. Both of mine were filled with junk, mostly dust that had gotten wet to make this awesome disgusting sludge. If you can get at it from there, try to clean the sludge out of the collection tray and the little gutter. I ended up taking my whole unit apart so I can get the collection tray out (dumb design, you have to take apart the whole dang casing to get at two screws that hold the collection tray in).
how warm is the basement,if the temp of the basement is lower than say 70 degrees,the unit will not function,true dirty coils can have this effect also and a refrigerant leak on these will cause the same result,if the temp is low,use a fan to move the air and this will help with your humidity problem too
If the room tempature is close to 60, the coils may be frozen (completely encased in ice). If this is the case, move it where the water can drain off - about 1 gallon which may NOT run into the drain bucket. I out mine over the floor drain. Turn off and it will defost over night. Only specially made dehumidifers work below a room temo of 60 degrees (the temp of a basement in winter). Does it need to be running? A digital humidity sensot from Radio Shack is cheap and may tell you the humidity is OK - only 50% or less.
E1 code for the primary humidity sensor behind right side grill. Unit MUST be unplugged from outlet. Take right side grill out, unplug sensor from wire socket and plug back. If no help, you need new sensor.

An electric dehumidifier includes a refrigeration cycle that is very similar to a window AC units and refrigerators. They cool the air in the basement to condense and collect water and remove humidity, heat the air as a required consequence of the refrigeration cycle and dump it back to your basement.
Two sources of humidity in basements include warm outside air that naturally cools due to below grade earth contact and water passing from the ground though the floors and walls and evaporating into the basement. Dehumidifiers do most of the work in the summer when higher temperatures outside enable air to hold more water content.
In the winter, cooler outside air contains less moisture by weight eventhough it may be raining and the relative humidity in basement will be less because the air is warmed relative to the outside. The lower moisture content in the winter also absorbs the water passing through the walls and floor.
From an energy perspective, you may want the humidity set NOT below 50%. This will keep humidity below the level mold desires, but prevents the dehumidifier from doing more work and eating more energy than needed. A cheap battery powered temp/humidy meter left in your basement will help. Sources that include the "mold triangle" (temperature, water & food) often separate fact from expensive hype.
If the dehumidifier doesn't keep up, consider adding a moisture barrier to the basement walls and floors such as Dry-lock and floor paints to ****** moisture entry. Moisture barriers act very similar with water as insulation does with heat. They don't eliminate the need for a dehumidifier, but they reduce the work they do and energy they eat.
I Had an E error (not an E1 error) when I was fiddling with my humidity/temp sensor on the face of the radiator fins (behind air filter). The sensor was WET. I dabbed it dry, let it sit all day, and re-assembled. It works fine now.
Only thing I can tell you to do is to make sure that the evaporator in the back is ice and cold. If the evaporator is not cold the unit will never remove moisture from the air. And if that is the case you have a sealed system problem. The unit may have a leak so there is no gas in it. The compressor may not be working or the humidstat my not be working properly. So check those thigs out or if its under warrenty call for service.
