Question about Danby DDR401 Dehumidifier
My dehumidifier display is flashing 'E3' the fan blows air ,but compressor not running. A thorough cleaning didn't change anything. Can you describe what E3 means ?.

You can try cleaning the humidity sensor, which is on a circuit board
housed in a nylon clip attached to the cooling coils.
The sensor is in a plastic clip, which can be opened up and cleaned.
Some report success. Didn't work for me.
I ended up rewiring the unit so that a 5v control
line from the lower relay board goes through the SPDT bucket full switch,
turning on the control board when full (so it beeps), but otherwise
enabling the compressor and fan. The fan and compressor
are controlled by relays, which are driven by a ULN2003AN
relay driver. I fed the empty side of the full bucket switch back into
the relay driver to turn on the compress and the fan on high.
I plan to put a dehumidistat in series with this control line;
now it just runs till the bucket is full. A Broan DH100W dehumidistat
is 20 bucks. Could also put in a rotary switch to control the fan speed,
but for me high is enough.
I think this machine is made by Goldstar for Kenmore and Delonghi.
Stuff is just made to break and through away these days, which is a shame.

This dehumidifier is built in such a way that the fan runs all the time;however the compressor works only when it is needed. These infos are not specified in the booklet. It does not work like the old ones.

There are many reasons for a dehumidifier to not work or collect water.
Here is a tip that I wrote to help people to figure out what is going wrong with their dehumidifier.

Be Safe or don't do it....
On the side with the lint screen, remove the five screws holding the top panel in place. The sensor that needs to be checked in mounted on the radiator fins. Remove the sensor and 4 pin connector. With a pin, remove the loose fitting housing the "sensor"...a circuit board that "shorts" with condensation...check corrosion and look for component damage on the oft chance the circuit board was damaged by some inappropriate poking or mechanical failure. Reassemble and replace sensor...
For a short life span...or out of warranty and only at your risk (IF have significant other or kids or pets or human DNA... don't do this...) .. guide wire through screen notch and attach to outer screen. Build fortress around exposed sensor and talk to insurance agent for a special rider...seriously be careful.
Did you? Clean screen and GENTLY clean fins of lint, etc....(vacuum's brush head should do the trick...)
Taking all appropriate safety precautions.
Here's the 100,000 (yen) tip....with humidifier unplugged, hold down the power button (green button in lower center) and plug in the appliance.
Watch the LCD screen as it conducts a self test...and wha...lah!.
Should have a working humidifier!
no really..."de nada". :"don't touch your moustache" "Doye toche moche"(?), "prego".
