Washers manufactured today and in the past few years are not designed with lint filters. The engineers rely on the dryer to remove any lint left on the clothes that doesn’t get flushed down the drain.
Residue or lint on load:
Did you sort properly? Sort lint givers (towels, chenille) from lint takers (corduroy, synthetics). Also sort by color.
Did you overload the washer? The wash load must be balanced and not overloaded. Clothes should move freely.
Lint can be trapped in the load if overloaded. Wash smaller loads.
Did you select the correct water level? The water level should be correct for the load size. Clothes should move freely in the water.
Did you use enough detergent? Follow manufacturer’s directions. Use enough detergent to hold the lint in the water.
Did you line dry your clothing? If so, you can expect some lint on the clothing.
Check the following
Was paper or tissue left in the pockets? Is your water colder than 70°F (21°C)? Wash water colder than 70°F (21°C) may not completely dissolve the detergent.
Did you use the proper cycle time for the load? Reducing wash time (duration) is another way to reduce lint.
These tips should help in reducing the amount of lint left on your clothes.
As far as the white blotches it sounds like the bleach is getting stuck in the dispenser or hoses from the dispenser to the tub.
If you never use bleach in the washer then you could have a problem with the laundry detergent that you are using. The washer itself is not able to cause this problem. It just fills with water, agitates, drains the water and spins the clothes out. If you have been using bleach on some loads, then you could have bleach residue on the top of the washer that the clothes are being dragged on top of that is causing these spots. In this situation, I recommend that you thoroughly wipe off the top of the washer to eliminate any bleach residue that could be present.
If the Oxi clean in not being dispensed then the problem may be with the Oxi water valve or the control.
This feature doesn't work with all cycles. Try the "Whites" cycle and see if dispenses the Oxi additive.
