Question about Dehumidifiers

Open Question

I have a Micromark D 250 de-humidifier that I bought in 1994. The water level cutoff switch has gone, although the mechanism/float within the tank is working fine. Where can I obtain a new switch please?

SOURCE: De Longhi DE220 De-Humidifier not collecting water

Hi there - you have to vacuum the filter several times. You can pull it out of the back left hand side of the unit. Vacuum it several times, and then start the unit on the lower fan setting, at a humidity level of around 60%. It will kick in after a bit, and then you can start adjusting the humidity level to where you would normally use it.

Sometimes - after you have vacuumed the filter, it still doesn't work. I used my fingers to pick lint off the filter, and ran a BIC safety razor over it as well, to try and get more out of the filter. You can also wash the filter in warm water, and leave it to dry over night. Don't put it back in until it's completely dry.

This will work! Cheers... E

Flashing light is on(power on/off pad)


red lights on dehumidifiers almost always indicate a full water catch bucket , this does not allways mean it's actually full of water , the machine thinks it is , some thing has gone ary with the level sensor in bucket , these most times are a simple float switch, that can get knocked out of position when one is emptying the bucket , also this same float switch also allows machine to know there's a bucket in place to catch water , sometimes bucket is not in correct place to catch water so machine wont start

Tank is empty the monitor says its full the humidifier is connected to a hose


If it has a float to detect water level, it may be stuck in the full position.

The De-humidifier thinks the bucket is full constantly


This occurs when either the float valve in the top of the water collection bucket is stuck in the UP position or the bucket was not installed properly, making contact with the bucket safety removal switch on the rear wall of the bucket holder.

Checking an correcting those 2 issue should solve the problem. Be sure to turn the unit OFF & unplug it before attempting corrective issues.

Didn't LG produce some bad Humidifiers several years ago and have a recall on not working units? I recall reading this in Consumers Reports. I bought one back then and it has not produced a drop of...


If has not produced a drop of water for several years, then it's not working properly. But, this may be a case of setting the humidity level to high. In other words, if you set it at 70% or Maximum, that's the humidity level that it will maintain, not remove. To remove humidity, the level must be set low (35% or Minimum).

To test the unit, based on what I just said, place it in the bathroom, set the level as low as possible and turn the shower on medium hot. Do Not turn the bathroom exhaust fan ON. As you leave, close the bathroom door. Return in 15 minutes, turn the shower OFF and check the bucket water collected. If there's any water in it, it's working fine. It was probably a case of the humidity level being set to high.

Hope this helped you. Please let me know. Thanks.

When my dehumidifier is on, it says there is 90 humidity. I come back an hour later, it is still running and no water in the bucket.


Hello,

If there's no water in the reservoir, first make sure that water is getting to the humidifier. The humidifier must have a good stream of water available to it. If there's water in the water line but the reservoir doesn't fill, replace the float mechanism inside the humidifier.

Take care.

How to clean filter


The de-humidifier is a niche product. Its only job is to remove moisture from air to alleviate the problems of mould and mildew. It is very similar in operation to a window air conditioner.

A dehumidifier though will add heat to the room, while an air conditioner will remove heat.

The de-humidifier is an appliance that requires regular maintenance. This may be because it’s icing up, overflowing, not removing enough moisture, or simply time for a good cleaning to maintain its efficiency. If you don’t feel handy enough to attempt this project contact your appliance repairperson.

The following is a step-by-step method used to return your de-humidifiers to its peak efficiency.

Tools required

1 Multi pocket container (old ice cube tray)

2 Long handled brush

3 Oil can

4 Rags

5 De-greaser or spray detergent

6 Selection of screwdrivers

7 New filter


1… Remove water collection bucket and put aside.

2… Remove the filter from rear of machine. Filer is usually within a frame and simply pops out. If no filter proceed to next step. If it is a disposable filter simply replace it with a new one. Other types are made in a plastic frame and can be cleaned and reused. To clean a filter lay it flat in the sink and sprinkle surface with powder laundry detergent. Plug sink drain and turn on hot water. Cover filter with enough water to submerge. Soak for 15 minutes. Remove from water and rinse. Hang up to dry while proceeding to next step.

3… Remove the rear grille from the main body of de-humidifier. If none proceed to next step. If there is resistance then look for hidden screws. If grille locks into cover proceed to next step. Once removed place the grille aside until later.

Tip: Dehumidifier may use different types and sizes of screws. Use ice cube tray to segregate.

4… Remove metal cover of de-humidifier to access inner workings. Cover screws may be difficult to see because are often painted to match body color. Usually two or three screws along each side of base. Once screws are removed lift the cover straight up. Use extreme caution at this point. Front grille may be secured to cover. Some fronts are put together like a puzzle. Parts often interconnect or are screwed to one another. If front grille lifts off with cover try to separate before proceeding. Front grille may lock into groove along front edge of cover. Avoid pulling off any wires from humidistat or indicator light.

5… When cover removed this will expose the heating and cooling coil. They may appear as one but are actually two separate coils in very close proximity. Both will need to be cleaned.

Use a narrow brush to remove surface dust and dirt from the front and rear surfaces of coils. Use an up and down motion to avoid bending fins. Area between two coils must also be cleaned. Use caution, the fins are soft aluminum and can be easily damaged. Once surface dirt is removed, spray with de-greaser or light cleaner. There is a good product on the market called HVAC cleaner. As the name implies it is meant for Heating, Ventilation, and Air Conditioner coil cleaning. If this is not available Fantastic Spray cleaner used in kitchens and bathrooms works quite well. Remove dirt and excess cleaner by slowly pouring warm water into fins. Do not allow the water to enter any electrical connections or components. As an added precaution cover the motor with one of the cloth rags to protect it from the water.

6… With cover, rear grille, and front grilles removed locate fan motor for oil holes. Add a few drops of oil to each end of the motor body. Use a general purpose (3in1) oil or clean motor oil. A #30 oil is sufficient. Three or four drops on both ends of the motor body are sufficient. Add the oil slowly, pausing a few seconds between each drop. If added too quickly over-lubrication will result.

7… Straighten any bent fins. Use a fin comb if available. If no fin comb then use something soft such as a Popsicle stick. Straightening the fins will increase the efficiency of the airflow through the coils. Use caution as these coils are filled with high-pressure refrigerant.

8… Wipe any dirt from fan blade using a soft rag. Do not bend blades. This would cause a vibration that would harm the motor.

9… Vacuum all surfaces including front and back of grille assembly. Vacuum underside of metal cover. Vacuum dirt buildup from base and any other exposed surfaces.

10… Drain any water left in the base and allow it to dry.

11… When completely dry plug in and test operation. On some models testing may require temporary override of bucket overflow switch. Test that cooling coil begins to sweat water within few minutes of operation. If everything appears okay unplug and reassemble. Insert water collection bucket slowly to avoid damaging float switch mechanism.

Adjusting dehumidifier on furnace


This model furnace does not come with a built in humidifier. Humidifiers are normally an optional add on. If you have a by-pass type humidifier it is none adjustable. Water level is normally float controlled and operation is control by blower circuit. When ever the blower runs the humidifier operates when in the heating mode.
