Have the freon checked, quickly. This condition can damage the compressor if you let it run like that.

You need to get some pan pills and put them in the drain pan.

SOURCE: Kenmore 580.75151500 A/C unit smells...


As you know, the evaporator unit (the one that the filter covers) gets a lot of condensation which is drained thru the back (outside) of the unit. That's why the unit is installed a bit tilted to the back.

The factory drain hole is too small and gets plugged up easy, some units don't even have one, the water sits for long periods of time. bacteria grows and the smell starts.

Unplugg unit from electrical outlet.

Make sure the unit is tilted back a little.

Drill two 1/4" inch drain holes in the same back bottom corner and set a bucket to collect the dirty water that will come out while cleaning it.

Get a quart of air conditioning grill cleaner (the ecol-friendly, it is purple in color) mix it on a spray bottle with water on a 1:1 ratio.

Use masking tape and some plastic to cover electrical controls in front of unit.

Following application instruccions on bottle, carefully spray on evaporator and condenser, avoiding electrical controls. Rinse with pure water, 2 qts. minimum on each grill, let it drain for about one hour.

Uncover controls and connect unit to power outlet.

Run the fan-only for about 10 min. and then the compressor.

There are more professional ways to service the unit, but performing this simple steps will keep your unit in good shape.

Don't forget to rate this post!! Good Luck!!

How do I get rid of the bad smell coming from my filter queen

Change all 4 of the filters, and wash the dirt container with soap, water and a little bleach. The only other thing that would cause a bad smell would be the actual motor, but that would be more of a burning smell. Good luck!

Smelly water with water softener

Your local home depot sells a product called AFFRESH that is made for front loaders to clean mold as well as stagnant water smells from washing machines. I have also hear other techs suggest vinegar and water but personally I would much rather have the unit smelling nice and flowery smell instead of a vinegary smell. Also it is important to note your drain line should be at least 6" higher then the top of your washer if it were less then the water that is supposed to leave the machine goes back inside the machine thus giveing some a stagnant water smell or like bad eggs.If you have any further questions message me back
Thank you

Hi I have a LG Intellowasher 7kg WM-1290FHB we have had some problems with it draining and it was flashing OE which was blocked drain etc.. we checked this and the pump which was blocked due to a lodged...

Hi from retired Englishman in SW France,
Bad odours could be coming from a few places.
  1. the plumbing u-bend or
  2. the fact that there is 'foul' water being left in the drum.
  3. No washes at 90 degree+ !
I would suggest checking the plumbing u-bend for trouble first, (you have done this next bit- but it makes interesting reading!!!) then following the notes on checking and cleaning the drain filter and the drain pump to ensure there is nothing 'obnoxious' hanging around the two of them! Finally run the occasional 90+ wash to kill bacteria.
Here are my complete and generic guidance notes for checking both the drain motor filter and the drain motor ;-0)
If you are unsure where the filter is, it is often behind the front lower (kick) panel (or in some machines at the rear in an awkward position!). These panels are either held on by (plasic) screws or will just pull off. Most filters are held in by a round cover/knob. Sometimes the filter will not come out with the cover and you will have to persuade it to come out to play.

It's surprising what people have found in theirs! It is always worthwhile checking it on a regular basis.
Now- whilst the filter is removed it is normally possible to see the drain motor and ensure it is not jammed by a foreign object such as a needle or a toothpick. It should be able to be turned by hand/finger- the power IS OFF!
At this point it is also possible to test if the motor works. No clothes or water in the machine, select a spin cycle and put the power back on. You should be able to see the motor turning at some point, possibly straight away. Using something suitable like a glove see if it is easy to briefly slow the motor down. If it is easy then the motor is malfunctioning.

I would not think the smell will be coming from/through the split in the rubber- not unless it is emanating from the u-bend.

We always use an anti-calcium powder in the wash AND I run decalc through it frequently as we live in a VERY hard water area ;-0(
Certainly carry out some 90+ washes fairly regularly, to make sure any bacteria is vanquished.

If this has assisted you please consider a 4 thumbs up for the rating.
Thanks and good luck,
John C

I did not replace the water filter for a while, when I replaced it, the water taste and smell molded, HELP!

You will need to remove off the filter and flush the entire system befroe the new filter is replaced. So take the filter out and clean up use some light dilute pottasium per manganate( KMNO3) as a disinfectant or use any what you have to get rid of the mould taste, flush out well , clean your filter again with some light disinfectant and reset. So not use the first set of water/ice maybe to clear up all traces of bad taste. This will get rid of your problems. Good day

Yes you can use lots of soapy water & pressure washer or hose to clean the vortex unit but remember it will take at least 36 hrs to dry out internally.

Moldy smell

Turn it off, unplug it. Remove filter and check if filter and/or filter and pump housing are clogged with something "smelly". When you're at it check the drain pipe for too.
