Try a Power Reset. Before you go to bed, cut the power to it using the breaker, the plug, or isolation switch. Try next dinner time. Press and Hold the On switch before you turn it back on to fully dissipate power.

It seems that you are out of cycle; meaning you are washing on rinse phase and the you are not getting water on rinse because you are at the end of the cycle. Try this; set the washer to the end of the rinse cycle, let it spin and stop. then wait 1/2 hour then start a wash you will be at the beginning of a new wash 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.

WASHER WILL NOT RINSE:
If your washer doesn't go through the washer rinse cycle, the most likely cause is the water valve. What happens is the water valve will stop letting cold water into the washer; therefore, once the washer gets to rinse it will either stop or not do anything during the whole rinse cycle.
This is because when you selected your water temperature, you selected warm/cold or hot/cold. The hot water came in and you didn't notice any problems. When it got to rinse, the cold water the cold water won't come in. Therefore, the washer does nothing.
To check the water valve, first cut the water off and remove the hoses off the back of the washer. Then one at a time point the hoses inside the washer tub and turn the water back on. If you don't have good water pressure, turn the water back off and remove the strainer that should be in one end of the hose. Inspect the strainer to see if it is stopped up, clean it and reinstall it. Now repeat this test. If you have good water pressure now, reinstall hose and your problem is fixed.
If you still don't have good water pressure, the problem is in your house plumbing and you need to call a plumber. If you had good water pressure the first time you performed the test, the water valve is bad and needs replacing.
TIMER
If your washer doesn't go through the washer rinse cycle the timer may be the problem. Sometimes the timer gets stuck in the middle of the cycle or won't turn at all. If the washer runs, but the timer doesn't turn, the timer is bad and needs replacing.
Do you have anti-flood hoses leading to the machine. If you do there is probably a loose tube in the back causing a small leak. When the hoses detect that water is still flowing after a certain amount of time due to the leak it shuts down and causes the machine to turn off during the rinse/spin cycle

The typical cycle is;
fills to selected water level
agitates wash cycle
drains wash water
spins wash cycle
fills to selected water level on rinse cycle
agitates on rinse cycle
drains rinse water
spins final time
end of cycle

LF = Long Fill

LF flashes when the water level does not change for a period of time after the valves are turned on OR water has disengaged the basket but control does not detect a water level change.
Is water supply connected and turned on?
Are hose screens plugged?
Is water entering the tub? If so check pressure hose connection to machine/motor control.

I have exactly the same problem. I am currently getting around the issue by letting the machine do the washing then at the end of that cycle do a manual rinse cycle.

POWERUP, YOUR WASHER COULD BE THE LID SWITCH OR THE COLD WATER VALVE. AT THE END OF THE WASH CYCLE, THE MOTOR WILL SPIN OUT THE WATER, BUT ONLY IF THE LID SWITCH IS ACTUATED. IF THE SWITCH IS BAD, IT WILL NOT SPIN OUT THE WATER AND THE TIMER WILL NOT ADVANCE FROM THAT POINT.
IF THE WASHER SPINS, THE NEXT STEP IS TO FILL WITH WATER FOR THE RINSE CYCLE. MOST WASHERS USE COLD WATER FOR RINSES. IF THE COLD WATER VALVE IS RESTRICTED OR FAULTY, THE WASHER WON'T FILL. IF THE WASHER WON'T FILL, THE WATER LEVEL SWITCH WON'T ACTIVATE AND THE TIMER WON'T ADVANCE TO THE NEXT STEP.
