Question about Venta - Airwasher LW44 Air Purifier

Open Question

Venta LW 44

I accidentally pushed the button that said "accept" but none of the solutions helped. Does anyone over there have experience with this particular humidifier/air cleaner? It is a plastic boxy thing about 8"x12". It has a connected al together bunch of plastic discs. The discs sit in the water. On the inside top is a motor and fan. This machine is 5 years old. However, I have only used it for about 18-24 months. It is not calcified or dirty. The motor seems to run. The fan turns from slow to fast depending on the speed I push. Their appears to be no obvious way into this motor. The plastic circular disc assembly is supposed to turn. The fan then blows air on the wet discs and it supposedly cleans and humidifies the air. I'm not sure about the cleaning part but it is a good humidifier. Pretty quiet. So now, is there anyone there who can give me help based on this particular machine?

    It's me again. A few months ago you sent me the link to the Venta LW44 manual. I fixed the problem at that time but have another problem and cannot find the link. Could someone please send me that link again? Fargosrp

SOURCE: Water wheels do not turn

Unplug the unit from the A/C outlet.  Turn the fan unit over, and with your finger, spin the fan as fast as you easily can.  Tooth like projections should rotate out of the lower most part of the assembly.  These teeth drive the wheel.  If they don't come out, the problem might be in the seating of that silicon rubber nipple, or the "tooth" assembly could be gummed up with algae and deposits.  You can wash it out.  The problem with mine is the teeth work, but the wheel still doesn't move.  I have emailed the sales office for help.  I love the unit's performance, but it is temperamental.  Good luck, and please post, if you fix it.

When you add water, you should notice bubbles (just a few) on top of the water.  When the water no longer has bubbles, the additive is shot, and you should wash out the tank.  We have dirty air, and it takes about 2 weeks for us.  I spray it with Murphy's Soap to soak a few minutes and wipe it out with a sponge.  Rinse.   Spray the wheel similarly (all over) and spray with a kitchen hose, as hot as possible.  You may have to repeat.  I clean my wheel between tank cleaning, so it doesn't build up.  You should use the additive, because the water has to be slippery to work with the wheel.  Maybe you can find a different "wetting solution,"  that would be cheaper;  Venta gets an arm and a leg for it.  Good Luck.  I like the performance of mine, but it is temperamental.

SOURCE: motor runs but wheels don't turn

The manual available on this page is very helpful: http://www.venta-airwasher.com/html/technical_data.html

Here's what is says about the disc stack not turning:

Problem: Disk stack not turning
Check that the rubber coupling is properly inserted into the bottom of the gear.

It also indicates that there is a 10 year limited warranty, if your unit is younger than 10 years you should probably call Venta at 1-888-333-8218 to inquire about service.

How can I make my own venta Airwasher Water Treatment?


I use white vinegar and hot water. I soak the disk for a few hours. It's amazing. My venta is 10 years old. I also use different scented oils in mine to fragrance the room. I use it daily. I got a new venta but like the older model better. It is my sleeping machine it provides a white noise that I sleep very well to. The new one is too quiet and seems more fragile.

Can airwasher fan repair during working of palnt?


It will not help purify paint fumes and could be a source of combustion. It is best to ventilate using open windows and positive air pressure from a fan blowing from another room into the fume area. Hope this helps some:)

Venta l44 motor won't run less than a yr. old


I own a 3-year old Venta L44 in which the motor stopped turning the wheels inside. It just sat there humming and eventually got hot. I sent an email to the Venta web site asking if they had a recycling program -- they don't. Instead, they replied (after a few days) stating that the motor was covered under the 10-year warranty. They sent me a new motor which was super easy to install. It didn't cost me a thing. It nows works perfectly.

My Venta Airwasher LW44 motor won't start


Test the motor to see if it works. Make sure the motor is removed from the rest of the unit. To find out how to remove the unit please hit the "Go Back button and select the "How to remove the motor button"...
  1. Plug the unit in to a working outlet.
  2. Push the #1 speed button on top of the motor.
  3. You now need to engage the saftey switch to start the motor.
  4. Protruding from the motor are two plastic about 3-4 inch guiding arms.
  5. Look inside the end of both of these two guiding arms. One of the arms are hollow and the other one has a white safety switch in the arm.
  6. Use a pencil or small item to push in on the safety switch.
  7. If the fan sarts to rotate the motor is still working.
  8. If the fan does not rotate then the life of the motor has probably ended and a new motor is needed. ( insert motor part link)

Clean fan area


NOTE:It is easier to remove the motor when the upper housing is still sitting on top of the lower housing unit.
  1. Turn the power off by unplugging the unit.
  2. Next to the speed directions buttons there are thumb tabs. Press the thumb tabs so that they pop up and unlock the upper housing flaps. a tumb tab on
  3. The four flaps should then drop down like the peddles of a flower.
  4. Grab the center of the motor and lift straight up, be careful when pulling the power chord.
  5. The motor, fan and gear assembly should not be seperated from the rest of the unit.
This will let you clean with vinegar and water.

Great product. Germany design at its best
