Essick credenza humidifier water from right bottle drains completely when it is filled causing water to leak all over floor. just started this, the last three years it worked perfectly

If the water overflows from the water holding well in your Essick D46720 humidifier, there could be a few possible reasons:

1. Faulty Float Valve: The float valve regulates the water level in the holding well. If it gets stuck or fails to function properly, it can cause the water to overflow. You can try cleaning the float valve and make sure it moves freely.
2. Clogged Water Inlet: Check the water inlet on the bottom of the humidifier. If it is clogged with mineral deposits or other debris, it can prevent the water from flowing into the holding well at the proper rate.
3. Broken Water Tank: If the water tank is cracked or damaged, it can cause water to leak out of the holding well and overflow.
4. Incorrect Water Level: If you are filling the humidifier beyond the recommended water level, it can cause the water to overflow.

To fix the issue, try the following steps:

1. Turn off and unplug the humidifier.
2. Remove the water tank and check for cracks or damages.
3. Clean the float valve and make sure it moves freely.
4. Check the water inlet for any clogs or debris.
5. Make sure you are filling the humidifier with the correct amount of water, as recommended in the user manual.
6. Plug in the humidifier and turn it on to see if the issue is resolved.

If the problem persists, you may need to contact the manufacturer for further assistance or consider replacing the humidifier.

if you can see how much water is in it just fill it when its down.otherwise figure out how the float switch works and find out why it doesnt now...common sense rules

not understanding how it works will get you that assumption
the full bottle will slowly empty when the water level in which it sits gets low enough for the atmospheric pressure to displace the water and let in an air bubble
That way there is always water for the unit to work
Same principle as the bottled water drink coolers in the office
putting a hole in the bottle and you will have water all over the floor
you need to check the humidity level of the air because if it is too high then the system will not work and so the bottles will not empty--really simple principle

Ours empties both bottles in one day. That is normal for a dry house. If your problem is that only one bottle empties and not the other, make sure the bottle is properly positioned on the bottom cap valve. To check this, put in only the bottle that doesn't empty by itself when the console is empty. The bottle should "gurgle" as it starts filling the bottom of the console. If it doesn't, re-position it until it does.

This is a sealed bearing motor so there is no oil ports. You can blow out with compressed air and spray motor shaft with WD-40. Be careful not to spray any lube inside motor. If you can get to them blow out motor cooling ports .this should help motor run cooler and quieter. Hope this helps you. Thanks

If the unit is on carpet, use the caster feet supplied with the unit. The weight of the bottles causes the front of the unit to be lower than the back. This prevents the sensor from switching bottles, causing the left bottle not to empty. The caster feet keep the water sufficiently level for the sensor to work.

Here is another thread on the matter.

Hi they should be a hose going to a drain in the floor there are insrtuctions on the wed just google the make and model and you can down load them

had to order mine from the company by calling 18006543545 part #509229-1 Cap, Valve assembly

Normal no, common yes. $10 says the right bottle drains first..... If you want to get the other bottle to drain put a shim under the side that is not draining.
