Washing white clothes washing in machine become dull very quickly... even if white clothes are washed separately...Any clues to improve that?.....

Why is my washing machine not washing properly?
A common reason why your washing machines is not cleaning clothes properly is because the line leading from the detergent tray to the drum has become clogged up with washing up powder. This means that just a small amount of detergent actually reaches the drum - the rest of it becomes stuck behind the blockage.

You can't. Best option is not to mix colors with white when doing hot wash. Generally colors on own go well with cold wash with the right detergent. When you get new colored clothes like pyjamas rinse separately overnight to get non fast colors out and then put in the general laundry. But always keep whites on separate wash.

These washer are notorious for linting, there is no real solution, reduce wash time to bare minimum, try sorting clothes into different categories, whites separate washed from dark clothes, use good quality detergent. The only way to fix this problem completely is a neutral drain kit, I do not believe Maytag sells one.

WASH PERFORMANCE INFORMATION
12.1 Creasing
Creasing can be caused by over loading SmartDrive or the dryer. Permanent Press or Delicate
cycles have been designed to minimise creasing as they use a lower spin speed. Do not leave wet
clothes to sit in the washer or laundry basket.
12.2 Soiling
Soiling is the result of insufficient detergent for the load. White clothes are better washed
separately. Separate lightly and heavily soiled items, as clothes can pick up soil from dirty wash
water. Cold water below 20oC does not wash effectively. Select the wash temperature according
to soil type. For example, blood and mud are better washed in cold water, while sweat and oil
based soil wash better in warmer water. Loads made up of articles of varying sizes will wash
better (e.g. full loads of sheets may not wash that well). Hard water requires more detergent than
soft water.
12.3 Linting
Wash lint givers (eg. towels, flannelette sheets) separately from lint collectors (eg. synthetic
fabrics). Over loading SmartDrive can increase the likelihood of linting. Insufficient detergent for
the load can increase linting as there will not be enough detergent to hold the lint in suspension.
Over drying synthetic fabrics in a dryer can cause a build-up of static electricity and result in the
fabrics attracting lint.
12.4 Detergent Residue
Over loading SmartDrive can result in detergent residue being caught in the creases of the
fabrics. If this occurs, decrease the load size. Some detergents need to be pre-dissolved. Check
the instructions for the detergent. Cold ambient temperatures, cold washes or short agitation times
may not let the detergent dissolve properly. In these cases pre-dissolve the detergent.
Overdosing of detergent can also cause residue when foam breaks down and will show as white
specs on the clothing. Poor quality detergents can result in residue.
12.5 Black Marks on Clothes
A build up caused by the interaction of fabric softener and detergent (scrud) can flake off and mark
clothes. Do not use too much fabric softener, maximum 75cc. If this is a problem, it is
recommended that SmartDrive is periodically filled with hot water, plus 1-2 cups of dishwasher
powder and left to soak.
12.6 Grey Marks on Clothes
Not enough detergent for the amount of soil on the clothes can result in grey marks on clothes. If
this is a problem it is recommended that SmartDrive is periodically filled with hot water, plus
detergent and left to soak.
12.7 Dye Transfer
Wash and dry non-colourfast clothes separately. Non colourfast clothes left sitting in a washer or
laundry basket can transfer dye to other clothes.
12.8 Tangling
Washing with too much water (i.e. under loading) can cause the clothes to tangle around each
other. Do not load SmartDrive by wrapping clothes around the agitator.

It could possibly be rust marks made by a loose screw or something.

Might try cleaning washer with full load of hot water and a product called Afresh

Hi! I am a habitual cleaning type person and clean clothes rate at the top of my list. I have 4 recommendations that SHOULD help tremendously for ALL your clothes but is most evident in your whites.
#1 is the right washer. I NEVER knew how clean my clothes could come out till the past year and a half I finally bought front loader. And let me tell you was I ever surprised at how clean and soft they were, LIKE NEW! Those old top loaders,even the new ones are no comparison to the front loading systems. BUT expensive if you have to go out and buy a new one BUT also a GOOD excuse to tell hubby you need a new one...LOL
#2 Always use liquid detergents, they seem to wash and rinse out so much better than any powder
#3 A HUGE helping hand I discovered some 30 years back that I STILL have not found that can be beat is "BIZ" bleach. It's miraculous! It's a great pre-treater to soak badly needed whites in and helps to retain bright colors if used in non-white laundry. Actually I even use it in a powder form. AFter loading all my clothes in m y front loader I scoop out a cup and actually scatter it OVER my laundry. Then add the liquid detergent (Tide or the like, I get mine at Costco or Sam's club depending on what region you live in) and wash like normal.
#4 Last but not least, for whites and ALL colors I have found nothing better than DAWN dish washing liquid. Immediately pre-treat ANY stain no matter the size with Dawn and just fold it over and toss it in the laundry. Best if washed within the same week at the latest.
GOOD LUCK to all you Domestic Goddesses! ;-)~

Do you wash whites separately or with bleach? Sometimes changing up the loads to whites with bleach would kill the germs.

You don't have to do the soaking. Use powders for 'front loading machines'. Read your users' manual. There will be settings for woolen clothes, cottons, quick wash, long wash,etc......

Terri, you may need to contact Maytag on this one. Here is service bulletin that was released in June of 2002... "Date: June, 2002 No: TDL0008A-S, MAH5500BWW, MAH5500BWQ Issue Software Improvements: A software improvement was introduced to the machine control board. The improvements focused on.
 Reducing the number of wet clothes loads, spinning and draining complaints.
 Modifications to the time estimation displayed toward the end of spin cycle. Display will no longer fluctuate erratically, time remaining.
 ?dO? is no longer displayed when the door is open. Warranty See specific product for warranty information. Action This board modification was phased into production without a series change. Inventory at the National Parts Center was purged and replaced with the new control board." Hope this helps.
