Yes, it's easy to fix. Turn the Master ON/OFF Switch to OFF and unplug the unit. Remove the air intake filter and clean it. You can vacuum it or wash it. If you wash it, use warm water and dish washing liquid. Rinse and allow it to thoroughly dry before reinstalling it. DO NOT operate the dehumidifier without the filter installed.

The above should take care of the O1N Error Code.

I have a Blyss WDH316DC dehumidifier with E3 in display. What does this mean?

What E3 Means? This is simply an error code with your dehumidifier please.

It s not clear whether you can attempt to reset your unit or fix it on yoir own. So sorry about this.

It appears yoir unit requires repair by a qualified dehumidifier service technician.

You can exploit the warranty if this is still valid. Simply return to point of purchase with your original receipt

I have a Frigidaire LAD504TDL dehumidifier and code 'ES' shows on display. What does this code mean? Unit runs but not much water in tank.

Good Morning Mark, thank you for your post!

I see that your Frigidaire dehumidifier is displaying an error code of "ES" and you would like to the meaning of that error code. The "ES" error code stands for evaporator thermistor error. This could be a possible problem with your control panel, thermistor, or a wiring harness. I would recommend contacting your manufacturer for further assistance with your dehumidifier. Best of luck! -Matt


Followed turn on instructions in manual.CO display 2 days. continually. Unit gets Very warm & fan runs if turned off. Have to unplug to stop. Unit used approx.3 mo in '14 & just restartd this week.

could you be mistaking the room humidity indicator for the time? reason I ask is on these one display units this happens more frequently than Id care it too , the one display shows both time and room humidity also set point humidity , the only way one can tell is on some models there is a tiny light that shows up next to labeled function , easy to miss It , also if your machine is sort of new (last few years) it has been decided that it's more efficient to let the circulation fan run all the time , regardless of room humidity . this makes it a little annoying (noise) but they do cycle the compressor to regulate the room humidity

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.

Fault Codes

This is more of a tip since I have not actually fixed anything yet. As a test, remove the upper front cover where the buttons and displays are. (2 screws on the bottom then pull off a the plastic snaps) Inside the case on the far left, there is a piece of crimped copper tubing, open on the top end, welded to the refrigerant line, with a black sleeve covering 2 wires out the bottom end. This is a thermistor. I CAREFULLY applied heat with a butane lighter (the mini torch kind, not the "candle flame" kind), taking care not to burn anything. I applied ONLY enough to make it slightly warm to the touch. Do not think of melting anything, as this is not the purpose. Applying too much heat could damage the thermistor. With the bucket in place, the unit started right up. After I did this, it failed again in a few minutes, so I heated it again, and thus verifying it as the source. I have done it a third time, never getting it much over room temperature, and it is still running after almost an hour after doing nothing else. Since this temperature sensing is an analog function to the microcontroller that runs everything, the fault could be any bad connection or solder joint along the way from this thermister to the controller. But is sure appears something in thermistor. I hope my description is complete and clear. Good luck.

Dead dehumidifier

Pull the bucket out... reach up under the bottom edge of the display bezel and pull down on the back edge to get the filter out; rinse out/off thoroughly, dry and reinstall it...

Get some airflow thru there!

Good Luck!

I dropped the water bucket by accident on the dehumidifier, and I have the same problem. Here what I found :
First, remove the water bucket and find the circuit diagram, it is very useful.

E1 code is related to the room humidity sensor, E2 code is related to the room temperature sensor and E3 code is related to the safety thermistor sensor. If you have one of these error code displayed, you will probably have to replace the sensor.

The humidity and temp sensors are located on the same board. To access it, remove the water bucket and you will see the 2 screws holding the front panel. Remove the screws, then gently prayed the front panel. Be careful, there is two plastic clip on the top of the panel and they are really easy to break. The board is located at the top right, under the cover. The safety thermistor is located on a pipe on the right side of the dehumidifier.
