WMB91442L washing machine not completing cycle

Could be several reasons:
- Selected the "Night cycle" program (means standing with the drum full of water, reason: too much noise in the spin cycle)
- Set to the "Rinse hold" (means standing with the drum full of water, reason: wrinkles on the clothes)

According to your description I think that this is not a failure otherwise error E20 will be appears on display.

Once the washing programme has come to an end, END illuminates on the programme progress display.
If RINSE HOLD was selected, the display beside the START/ PAUSE button flashes.
1. After a rinse hold, the water must first be pumped out:
- Either press the START/PAUSE button (the water is pumped out and the washing is spun according to the completed programme;
After the START/PAUSE button is pressed again, the spin speed can still also be changed during spinning), or
- Turn the programme selector to PUMP OUT and press the START/PAUSE button (the water is pumped out without spinning),or
- Turn the programme selector to SPIN or SHORT SPIN and press theSTART/PAUSE button (the water is pumped out and the washing is spun or gently spun).
At the end of this programme step, the END indicator will illuminate.
2. Open the door.
As soon as the DOOR indicator lights up green, the door can be opened.

I would replace the pump impeller first!

This is completely normal, the machine puts water into this chamber during the rinse cycle to wash the softener into the machine.

Check that the cold water is turned on. The washing machine uses cold water to rinse, and if the cold water is not on, unit will end without completing cycle.

I have found with my aquasmart that if you use the 'high efficiency' the water does not cover the clothes sufficiently which is why the soap residue (noticeable more on dark clothes) is visible. I don't use high efficiency. even on conventional sometimes I still have to check that the water level is high enough. Also **use only liquid, low sudsing detergent and do not put it on the clothes-use the dispenser only. As for my machine... Time for the repair man to check the sensing I think

Most diswashers have a complete cycle that lasts over an hour. The machine fills with about 1.5-2 quarts of water, rinses the dishes for a few minutes, then empties the water, then fills again with new water and rinses for a few more minutes, then empties. This is to get a good bit of the looser gunk off the dishes, and to soften up any other stuff that has dried on there. Then the machine fills a third time, the soap door pops open, and it washes for a much longer time to hopefully dissolve away pretty much anything left on the dishes. Then it empties, and does a rinse the soap off cycle, and usually a final cycle that rinses again with a little bit of rinse agent to help them dry quickly.

The whole process uses about 2 gallons of water.

Apparent malfunction in the timer circuits. Specific Component replacement not available.

washer fills up but wont start washing i can turn the knob just passed the numbers and the little marks and it starts washing and when it gets to the rinse cycle it wont rinse but when it gets to spin cycle it spins good

You will need to have a qualified LG technician come out and see what the problem is.  You may have a water level switch issue.

Following up my comment from yesterday, I took the machine apart and discovered that the black rubber cover on the valve that releases the cold water had perished and cracked, and wasn't opening properly.
I tested the hot and cold solenoids and everything checked out ok. Was just the cold valve sticking.
The wash cycle was working because I was using hot/warm water. As the rinse cycle needs cold water to get started, it was not working and the rinse and spin cycles wouldn't complete.
I have swapped the valves over for now (put the working hot one on the cold side and am using cold water only). It's working while I order a replacement...
