Question about DeLonghi DHE90 Dehumidifier

Open Question

My DeLonghi DHE90 runs but after filling the bucket with about 2" of water the radiator turns into a big block of ice and freezes solid and eventually the bucket handle freezes to the unit. There are flakes of rust all over the inside of the unit, and now red rust can be seen on the exhaust grill. It never stops running once it starts and the compressor gets very very hot! No more water drains into the bucket. Its not shutting of the freeze cycle for some reason!

If yours has a button/switch to turn on a pump, that will redirect the water to the drain. Sllee

same thing happend to me. I wasnt sure if it was the settings or me. I unplugged it for awhile, read thru the instructions turned it back on setting it according to the instructions and it began to work again. Not sure if it had to do with the unit being off for awhile or I entered the correct settings. Im just happy it began to run again

SOURCE: Pump not pumping

I have bought a used replacement pump and barrel. First I swapped the barrel, still did not fix it. I replaced the pump, used pumps show up on ebay every once in a while. The new used pump worked great.

Place the old pump on a table with the two silver screws to the right, and I opened up the old pump, very carefully unscrew the two screws. Twisted it to get it off the nipples, and pulled it apart. If there are 2 springs inside the long chamber to the left you have a broken spring. The long little spring should be connected, through the shaft to a cap to the right. Mine spring broke off at the cap and the little piece was blocking the hole. The cap is fine, I need to find that spring. The spring I am talking about is about 1 inch long and fatter on one end than the other.

My dehumidifier does not seem to be working properly. I can't find the manual to tell me what the settings should be. Would appreciate your help. It is a DeLonghi DE400P. Thanks Shirley


What is the specific problem? Is no water being collected by the dehumidifier or do you have another issue?

Make sure that the dehumidifier is in a room in the operating temperature range (at or above 44 degrees F). Make sure that the room door and windows are closed and that the room is not larger than 2200 square feet. Make sure that the collection bucket not full and is properly seated in the dehumidifier. Check and clean the air filter on the dehumidifier. (Vacuum the filter or rinse under running water three times. Then wait until dry to replace it in the dehumidifier.) Look at the coils of the dehumidifier. If you have ice on the coils, defrost the unit (turn off, unplug and wait for it to melt). If the ice reforms quickly, you may have a leak in the coolant system. Then the unit needs repair.

Next make sure that you have good air flow around the dehumidifier and that the desired humidity set point is lower than the humidity of the room.

I hope this helps.

Does not collect water in bucket but runs all the time


Does it have a filter?

also:

"
It may be that the humidity level or temperature in the room where your dehumidifier is located is too low.

When the outdoor temperature is below 50 F, the indoor air will be dry even when the air inside is warm, therefore when it's cold outside the dehumidifier may collect little or no water.

Air conditioners will also remove moisture from the room, even if it's hot and humid outside, resulting in little or no moisture collecting in the dehumidifier bucket.

Some dehumidifiers have a deicer which turns off the compressor but keeps the fan running. When the compressor is off, moisture is not removed from the air. The deicer turns off the compressor when the room temperature is cold.

Some dehumidifiers do not have a deicer. If the room temperature is low enough, ice may form on the evaporator coil. The ice prevents the dehumidifier from removing and collecting water. If ice forms on coils, unplug dehumidifier until ice melts and room temperature rises."

My DD50E has stopped collecting water and filling up. It runs but doesn't collect water.


Hi,


There are many reasons why a dehumidifier will not work or collect water.

My humidifier is leaking inside. i notice there is a small tubeoutside the bucket and not connected to nothing so it leaks out.what should i do?


If the room temperature 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 defrost over night.
Only specially made dehumidifiers work below a room temp of 60 degrees (the temp of a basement in winter).
Does it need to be running? A digital humidity sensor from Radio Shack is cheap and may tell you the humidity is OK - only 50% or less.

You should be able to connect the unit to a drain hose - then you won't have to empty the bucket. Have you tried that?

Otherwise, you only have 2 options I can think of:
1) empty the bucket frequently (before it fills up) or
2) siphon off a bit of the water before jarring the bucket

BTW, I eventually gave up on using dehumidifiers unless I was trying to dry out wet carpet. They are a hassel, and they are essentially A/C units that doesn't give you cool air.

No water in bucket


possible that the cooling fins have frosted over...this happens when a cold surface appears in a humid room that does not have enough heat to prevent the freeze-up on the fins. If you look at the fins (above the water bucket), you may see the frost. One solution is to turn up heat in room, followed by placing a fan to blow air through fins if still frosted. If you do not have a frost problem, then ensure compressor is running. If comp is running, then return dead unit.

Will not shut off


My unit is a Fedders A7DH65B2A and your Maytag unit was made by Fedders and is just like mine w/ different label... I've purchased two of these units (one for me & one for my father-in-law) and they both quit pulling moisture from the air (but ran constantly) about 1 month past the 1yr warranty. My unit also acted really strange one day when the problem was occurring - it flashed on & off erratically and wouldn't power off unless I pulled the power cord. In short, I took it apart and found several issues and eventually figured out the chain of events that led to this: 1) The thermistor went bad and the unit could no longer sense when the evaporator coil started freezing up (normal situation that the unit should detect & then do a defrost cycle). As a result, the evaporator coil turned itself into a big chunk of ice (can see by removing the air filter and looking into that slot at the coil (looks like a radiator). 2) the big block of ice on the coil grew large enough to start making contact with part of the plastic housing above the evap coil that's used for the power control circuit board. The plastic in that area then got ice all over it and since it looks like a little tray, it will hold water (when the ice thaws) and then the power control board will be sitting in a puddle of water (or ice - either will cause malfuntions like not being able to turn the power off using the front panel switch). 3) the puddle of water in the power control board tray caused this circuit board to corrode (happens very quickly when the unit is plugged in since electricity accelerates this kind of thing...). So... a poor quality thermistor (this straps to the bottom right side of the copper pipe that loops out & back in to the evap coil and has a wire coming out of if) caused premature defrost circuit failure. This caused a big block of ice to form where it shouldn't be. The ice caused condensation/moisture/ice to form on/under the power control circuit board and corroded the circuit board and caused erratic power control issues. RepairClinic.com had a replacement sensor board (included all sensors - yes, the thermistor too...) so I purchased it (~$40) and used only the new thermistor off of it to plug into my original sensor board (and strapped it back to the evap coil w/ the chrome looking clip that was already there). Problem fixed! Well, almost... I did have to clean the corrosion off my power control board as well, but it survived luckily. After doing this to mine, my father-in-laws unit experienced similar symptoms. I did the same fix to his and presto... fixed. Cheap low quality thermistors on these units. I need to find a higher quality replacement thermistor before round 2 happens on each unit. Good luck!
