Question about Bionaire BDQ24 Quietech Dehumidifier

Does this dehumidifier auto restart after power interuption?

There are very short power interuptions where I live and I've discovered that certain pieces of gear (like a dehumidifier that runs in the background) should survive an interuption and restart afterward. I use lockout timers for gear like this, set to about 5 min, to prevent compressor damage from power flickering. But, of course, for this to work, the gear has to restart after outage. I've already got one dehumidifier, the Soleus 25pint/d, that does not auto restart... and it's a pain in the a__. Is the Bionaire 20pint/d the duhumidifier for me? Thanks Dave P.S. If anyone has any mods for making these dehumids survive an outage, please lemme know.

Thanks for a stab at it, JD. Well, sure, UPS units are an option. But realize that anything with a motor in it, i.e. a compressor, has a large current demand, particularly when it starts. Since a dehumidifier operates on a humidistat, there's no way to tell it 'you're operating on the UPS unit right now, so don't start up if you're stopped'. Starting the compressor on an UPS unit that won't support the draw will damage the compressor. UPS manufacturers specifically state these details in the fine print. But more to the point, I don't have to worry about this with my refrigerator, freezer, furnace, etc. It would be nice if manufacturers simply accomodated this rather common situation. I know that some do. It would be nice to have a list of all 25pint/d dehumids that restart after power failure. Also, it's also possible to restart, but on some manufacturer predetermined setting. So it would be nice to know which gear restarts after power failure and also resumes settings. It would also be nice to have a million dollars. All equal in likelihood.

But, thanks for the suggestion JD and have a great day,

Hey dehumidiguy,

Have you considered an appropriately rated UPS unit for ridethrough ? American Power Conversion offers a sizing calculator on their website that will tell you the size UPS needed to provide ridethrough based on the load size and the amount of time you need it to continue operating.

Good luck,

Frigidaire dehumidifier has an error code of EC and does not take in any water. The temp in the basement is a constant 68 degrees.

First, I'm not a Frigidaire tech.
* Check your warranty. Call for service.
* Contact (note Live Chat link);
*** following is for information only ***
* Checking basic problems;
* The humidifier will only run if the "Humidity" (water or moisture in the air) is higher than the current setting on the humidifier. If it's set to maximum dry setting then expect it to run almost 100% of the time. If it is set to a "wet" setting then expect it run only for short periods.
* Colder room temperatures will reduce the frequency of cycles as cold air will hold less moisture than warm air.
* You may note that running a AC unit in the same room as the dehumidifier will give you mixed results as both units will "fight" or work against each other. Humidifier will heat the air as it exits while the AC will cool the air. Best to not run the AC while the dehumidifier is in operation.
* Note that AC do "dehumidify" the air as it passes through. But not as effective as a dedicated dehumidifier.
* Be sure to check the tub and filter (make sure they are seated properly.)
* Contact Frigidaire or your local Appliance store for service.

Our new Santa-Fe Classic dehumidifier is leaking water from the bottom of the unit. It's also sending a small amount of water correctly through the tube for dispersal. We've only had it for two...

The classic model drains thru the clear hose using gravity. The drip pan in that unit is about 1/2 way up in the cabinet. Make sure the drain hose exits the unit and runs flat or downhill. If the drain hose is coiled vertically or run up hill causing water to trap within the hose it can cause water to back up in the dehumidifier drip pan and overflow causing your problem. If your drain is higher than the base of the dehumidifier, you can raise the dehumidifier or you can purchase a condensate pump kit that will allow the drain water to be pumped up to 15 feet above the dehumidifier.

The drain hose may have become disconnected from the drip pan as well. To check, turn off the humidistat to stop the dehumidifier from running. Next disconnect the cord from the power supply. Remove the six screws holding the cabinet side (with the label) from the cabinet and remove the cabinet side. The drain hose connects to a nipple on the bottom of the drip pan.

Contact Therma-Stor service for further inquiries at 1-800-533-7533 - they are located in the USA and are very helpful.

Dehumidifier is leaking from the bottom,also for a brand new home what should it be set at and should in run constantly or only at certain times?

Yes it should if it is a window unit. How long it runs depends on how much room space you want cooled and what size unit you have. If you live in an area that has high humidity you will want it to run more often to remove the humidity. Some units have a setting so that it is running all the time to circulate air, but the compressor is only on when the air is too warm.

Demudifier worked great, all a sudden it just stopped. No power. Now it won't start up. What should I try?

First, check the outlet that it's plugged into, to make sure that there's still power to the outlet. If there isn't, then the circuit breaker for that outlet has been tripped, in your home's circuit breaker panel. Leave the dehumidifier unplugged and reset the circuit breaker. If it trips again, without the dehumidifier unplugged, then the outlet is at fault. Perhaps there's a loose wire connection or the interior of the outlet is cracked.

If it didn't trip without the dehumidifier plugged in, plug the unit it in,. But, before you do, make sure the dehumidifier's Master ON/OFF Switch is OFF. Once it's plugged in, turn the Master ON/OFF Switch to ON and set your controls. If it runs now, GREAT! If it trips the circuit breaker again, there's either a short in the power cord or an internal electrical short. Which will require extensive troubleshooting to find.

Hope this helps you solve the problem. Please let me know. Thanks.

Ice build up got my curiousity. took off the front cover to find an electrical piece on the tray wire attatched. doesn't seem to plug into anything. wish i had the specs.

Its a condensation sensor...senses "short" circuit conditions or ionized water.

"Defrost" The circuit opens up and easily cleaned with 90% rubbing alcohol...use with care...(no flames or power ..all safety precautions, etc...)

Reassemble and reset dehumidifier per unavailable service manual. If you received one, would love the link!

Otherwise (unplugged) push power button and plug in appliance. Will power cycle and run self test.

Hopefully it works by now!

Code (CH) (01) on front panel, what does it mean?

I believe it is a water tank code. Re-seat the tank, unplug wait 15 seconds and replug the power cord and see if this resolves the error.

Background relating to other possibilities.
When the water bucket reaches its capacity, the bucket switch opens to shut off the dehumidifier. If the bucket switch fails while it is open, it will prevent the dehumidifier from running. To determine if the bucket switch is defective, use a multimeter to test it for continuity. If the bucket switch does not have continuity, replace it.

Dehumidifier trips ground fault outlet and no water in bucket

The compressor is trying to start and pulling high amps which trips the GFI...
You are better off replacing rather then repairing that unit.

Dehumidifier will not run.

Have they messed with the wires to the humidistat??
Either they are unhooked or they shorted out the wires and burnt out the transformer...

Runs, but overheated, tripped outlet causing freezer full of rotten food

There was a recall on these - it depends on the age.  I bought mine in 2003 or 2004, and they sent a repairman out to replace a circuit board.  Call Maytag to see if yours was in the recall.
