Water keeps running and draining right back out so it never reaches selected level

good solid commercial unit 13 kg

could be a timer or control board fault
my best guess is
faulty water level sensor

The F2 fault code indicates a problem with the washer's drain system, and you must troubleshoot the problem to determine how to fix the washer and clear the code.
Clogged Drain Hose The drain hose on a Kenmore washer should remain free of obstructions so the water drains from the washtub. the drain hose behind the washer can impede the flow of water from the washer. A drain hose inserted more than 4 1/2 inches into a floor or wall standpipe drain system can cause the water to siphon back into the washtub.
Stuck Water-Level Pressure Switch Your Kenmore washer uses a water-level pressure switch in the control panel to detect the level of water inside the washtub. You can find the pressure switch behind the control panel in top-load models or attached to the inside wall of front-load models. The round switch is approximately 3 inches in diameter with a clear or black plastic tube connected to the bottom or side of the switch. The tube runs from the pressure switch to the exterior washtub. As the water fills the washtub, it changes the air pressure inside the tube and lets the switch know when the water has reached a predetermined level. A stuck contact on the pressure switch can stop the advancement of the wash cycle and keep the water from draining. A few taps on the top of the switch with a screwdriver handle can release the contact and fix the problem causing the F2 error code.

The drain hose needs to be higher than the top of the water level and yes, there needs to be an air gap so the drain does not siphon. As far as temperature, the machine will automatically put in cold or hot water depending on the temps selected. You cannot get straight hot water from this machine...that is by design. You will have to live with the temps you are given...I know, it sucks!

if water just keeps draining check the drain hose,if it's down to far into the stand pipe the water will just keep siphoning out,if that's ok,when it starts let it run for the first two minutes and then it should reset and start,also try unplugging it for like 5 to 10 minutes and plug it back in,that will reboot the computer board.

The height of the drain hose outlet fitting must be higher than any expected level of water in the tub. It is most likely draining as fast as it fills due to water siphoning out. The machine is trying to fill the tub to the selected level, but can't reach it. The cure is to raise the level of the house drain to the height of the machine itself. Hope this helps!

Good day,
If it keeps filling, and can't then it sounds as if you have the drain hose positioned too low.
It must reach a point higher than the highest level the water will ever reach.

If the m/c keeps filling, where is the water going ??? if the m/c doesnt reach the required water level it will not start, check the drain hose at the back, make sure its at least 24" above floor level, if it lower then it will just empty as quick as you fill it on gravity.

water can't run out of drain until the drain pump runs. must be water level continuously rising, but slowly. definitely water solenoid switch problem. pl. open and clean if u can or replace.

This is commonly caused by a condition known as "siphoning". The following link explains:

http://www.fixya.com/support/r587481-prevent_washer_siphoning

The washer is filled when the solenoids on the water inlet valve are activated, allowing water to flow through the fill hoses. Once the washer reaches a predetermined level (as determined by the load level selector dial), the pressure switch senses the water level and shuts off the inlet valve. If the pressure switch was causing this problem, your water level would continue to rise to the point that the washer would overflow. If the water inlet valve was defective and would not shut off, you not only would have a washer that would potentially overflow, but it would also continue to fill when the washer was not in use. The key to diagnosing your problem is the fact that the washer continually DRAINS and cannot maintain the water level. Take your drain hose and pull it up from the standpipe. If you had the hose shoved down in the standpipe too far, or if the drain hose was fitted too tight, a sucking sound may be heard as you pull the hose out. You should only have about 6 inches of hose in the drain. There needs to an air gap around the top of the standpipe as well. This prevents a vacuum from forming which causes the water to be siphoned from the wash tub.

Read through the link I provided and let me know if you have questions. If you require additional assistance, please let me know before rarting the solution. I hope this helps you.

check the height of the drain hose. if you aren't seeing a leak on the floor the drain hose might be below the height of the tub. the water always seeks the lowest level and if the hose is too low the water wwill run right out
