Check your settings for your load.
Did you know when ecowash is on will reduce water temp. regardless of setting? pg4 #7
Have you used the clean washer cycle after 30 loads? pg11

chlorine bleach is a highly corrosive addition to laundry that is not necessary... try Borax and Hot water. If the clothes sat in the Bleach for the entire wash cycle it would damage them and shorten the life of the clothing fibers considerably...

lf means long fill check your fill hoses and make sure the water is comeing out. sounds like a problem with your inlet valve and/or your water from your house is not right.

RL means at the start of the CLEANING WASHER cycle a load isdetected inside the drum.

Try removing clothes from drum and start the cycle again.

try using less bleach

This is from not enough HOT loads.

Fatty deposits gather between the basket and tub during COLD washes.

Then they are being released in large numbers when you do your whites on HOT.

It is recommended to do 1 HOT load per week.

Do an empty load with some degreaser added (like Goo-Gone) on the fullest/hottest setting you have.

I can send you a PDF of the manual let me know..

If the washer does not come equipped with a "Clean" cycle, then run the washer on it's hottest setting. "Sanitary" or "Whitest Whites" will do. Hope this helps.
