Delonghi Dehumidifier DE400P / DH400P say...




By jgelman on Nov 10, 2007

" "
Machine worked great for 1 season. Turned it on the next season and comes right up to E1. I am very technical and have had all the covers off, checked all the connections, cleaned some crud out of the tubes, cleaned a little corrosion out of the humidity sensor connector - but can't get this thing to work or the error to go away. Any Help would be greatly appreciated. Thanks, Jon

-   Ok so I tried disconnecting the sensor from wire socket and when I turned it back on instead of getting error message E1 I now have Error message E2. My unit is less than a year old -   paall1

-   A few weeks ago the pump wasn't working so I pulled everything apart and found a small filter that didn't allow water to flow through it. When I removed the filter the unit worked fine. I didnn't notice any direction of flow note on the filter so I installed it reversed and it worked fine after that.

Now the unit goes to E1 right when you turn it on. I'll try your fix...Thanks!-   Guest

Hi.
It is simple and easy to fix. E1 code for sensor behind right side grill. Take right side grill out, unplug sensor from wire socker and plug back. It is solve problem sometimes. Unit MUST be unplugged from outlet.
If no help, you need new sensor .

Thank you.
Dimitry.

I believe the filter is actually a type of back flow valve. I pulled it off, cleaned it out with some bleach and water, put it back on in the same direction.
It works fine. Quiet with not errors
