I have a Kenmore Elite Dehumidifier. Yesterday it just stopped working. When I plug it in, the panel does not light up at all, nothing, no power! Warranty ran out last month. It is 13 months old. Thanks....

Debi, before we assume there is something drastically wrong with the unit itself. Let's look at some other things that may be causing the problem.

1. Is the outlet that unit is plugged into still have power? Has a circuit breaker in you home's
Circuit Breaker Panel been tripped? If so, unplug the unit, before resetting the circuit breaker.

2. Was the water collection bucket recently removed to empty it? If so, was it reinstalled
properly? In other words, was it installed "squarely" into the holder and making contact with
the bucket safety removal switch, on the rear wall of the bucket holder? If not, this would cause
the unit not to activate.

3. Does your model have a float valve in the top of the bucket? If so, the float may be stuck in the
UP position. Which indicates to the unit, that bucket is full. If you have a float valve, jiggle the
arm of float to make sure it moves freely. And reinstall the bucket properly.

I hope all of the above helps you to troubleshoot and solve the problem. Thanks for choosing FixYa.

The drawer is empty of water but the signal says 'full'. Is there a broken part? Thank you, Eileen

No, probably not. Either the float valve in the top of the bucket (drawer) is stuck in the 'UP' position or the bucket wasn't installed properly.

For the stuck float valve. Remove the bucket and look in the right or left corner of the bucket for the float valve. If it's stuck in the 'UP' position, jiggle the handle to make it return to the 'DOWN' position.

When reinstalling the bucket into it's holder (whether it had a float valve or not), be sure that it fits "squarely" from top to bottom into the holder. It should not tilt down at the bottom. The bucket must make firm contact with the bucket safety removal switch inside the holder.

Hope this helps you to troubles shoot and solve the problem. Please let me know. Thanks.

The dehumidifier does not shut off when the resevoir is full and therefore over can I fix this

Turn the unit OFF and unplug it from the wall. Remove the bucket and empty any water that may be in it. Then, look at the top of the bucket for a float valve control. It slides from left to right, depending on whether you want it to shut off at half full or three quarters full. Slide the float left until it snaps for 3/4 full or all the way to the right until it snaps for 1/2 full. The bucket must be properly aligned for the float to work.

In your case, the float may have moved to the middle. Or the bucket is not squarely into it's holder, from top to bottom.

Troubleshooting the above should solve the problem.

My dehumidified says its full but it is actually empty? what should I do?

The actuator switch, which is commonly called the bucket safety removal switch, is not making good contact with the bucket. Turn the unit OFF & Unplug it. Remove the bucket from it's holder and check the inside of the top of the bucket for a float valve. The float valve's arm may be stuck in the UP position. In which case, jiggle the arm to get it to return to the DOWN position. If your model doesn't have a float valve, look inside the bucket holder for what will look like a trigger switch. This is what the bucket must make firm contact with. Reinstall the bucket making sure that it fits "squarely" into the holder from top to bottom. When installed properly, the bottom of the bucket will not be tilting down.\

Plug the unit back in and turn the unit ON. If any of the above was corrected, the unit should turn ON and function normally.

Hope this helped you troubleshoot and solve the problem.

This usually caused by one of two things. The bucket is not installed properly or the float valve in the bucket is stuck in the UP position. The float valve is not in all models.

Turn the unit OFF & Unplug it. Remove the bucket, look in the top of the bucket on the left side closest to you. If you see a float valve you have that model. If the float is in the UP position, jiggle it so that it will return to the down position. Then reinstall the bucket. Plug the cord back in and turn the unit ON.

If you don't have a float valve, make sure, when you reinstall the bucket, that it fits "squarely" into the holder from top to bottom. When installed properly, the bottom of the bucket should not tilt down at all. The top, back side of the bucket must make firm contact with the bucket removal safety switch.

Hope this helped you troubleshoot and solve the problem.

Dehumidifier indicates that it is full even though it is not

Look inside where the water reservoir sits, you should see a small float. This float triggers a switch that shuts the unit off when it gets full. You want to make sure that float is able to move freely (not caught up on the edge of the reservoir), and that it makes a "click" sound when you lift it up. If it's moving freely, but the unit still thinks it's full, you may have a faulty switch.

The unit is several years old - the float keeps falling in and the unit shows full -can I get a new float and will that fix the problem?

If the float falling in tells you its full probably not. Unless the float floats off a switch. Then a new float that wont fall off would probably do it.

If the float keeps falling off...why not tie a small piece of fishing line to it and suspend it above the switch? It will stay where its needed until water lifts it up.

'bucket full' light on, but bucket empty

There is likely a switch operated by a float to turn that light on and turn off the compressor, sometimes manufactures use a rubber "O" ring on the float shaft and they can slip. take the cover off the pump and check the float or in some cases one of two floats are used. Once float turns the pump on and off and the second float shuts OFF the compressor and turns ON the full reservior light.

Sensor says it's full; it's not full and won't operate

Check for a sticking float arm. The float arm activates a microswitch when the tank is full. Also look for a sticking Microswitch. Here is a picture of the float arm.......follow the arm to the location of the microswitch. If neither are stuck, look for a loose wire in series with the microswitch. Hope you find this to be very helpful moving forward. :-)

Bucket full light will not go off and unit will not operate (there is no water in the bucket).

The bucket full light is controlled by a manual 'float' switch in the bucket itself
-when the water level lifts the float ...turns on the light and does not allow the unit to operate because it believes it is full.

It is very common for the 'float' to gets misaligned, hung-up, etc. when you remove and re-insert the bucket. Sometimes the 'chain' gets twisted, turned...which does not allow the float to ...float...rather it is 'hung-up' which indicates it is 'full'...when in fact it is clearly not.

To check this:
  • remove bucket from unit
  • look into the top of the bucket opening to locate the 'float'...generally 2" round plastic ball on a shaft, (or chain)
  • softly cup the float in order to lift this up...with the unit stilll plugged see if the light goes off...this is very likely
  • then be sure that the float mechanism is able to freely 'float' in the space....i.e. you are trying to simulate the impact of rising water levels in the bucket
  • as it rises (in your hand the machine will turn off/light it drops....the light shuts off, allowing the machine to run (when humidity levels demand it)
  • then re-install the bucket....being very careful to lift the float, while you insert it...there is generally a little nack to it...but you quickly learn how to do it easily (I just reach into the space...cup the float...put the bucket on an angle...slide it in....release the float into the bucket...(remove hand)...then finish pushing the bucket into place
-hope this helps
