Well, there are two main possibilities: Inlet valves and pressure sensor system. to test the inlet valves, turn off the machine, do they stop? Dirt can keep them open.
If power off stops the water, I suspect the pressure system. There is a component outside at the bottom of the drum that measures the water volume, using pressure. This collector component sometimes gets clogged with detergent. If it is open, test the transducer at the other end of the plastic hose. The system is designed to stop the power to the inlet valves when the pressure builds.
This is most likely a problem with your drain line. Check to make sure it's not filling with water and that there is a gap around the line in the drain hole to prevent vacuum lock. Give the hose a good shake and see if that dislodges any stuck water.
You could also have something caught in the valve which is preventing it from opening and closing properly.
I mostly answer front load problems but ' out of balance' is a common problem with both! So- I don't know your particular machine but the initial cure is the same. It is necessary to ensure absolutely that the machine, even when empty, has all 4 feet very firmly on the floor, and I mean firmly ;-0)
Doesn't matter whether it is empty or not but switch it off then- very firmly push one front corner diagonally into the centre of the machine (sorry about my UK spelling!) and see if the machine moves or rocks AT ALL, even the slightest. If it does you will need the open-ended spanner which came with the (new) machine........which of course went missing a long time ago?!! An adjustable spanner will suffice. Adjust the foot under that corner downwards until it is very firmly- almost pushing- against the floor but not so far that the corner lifts up! If this corner did not rock do the same to the other. Once you cannot rock the machine the slightest little bit, screw the locking nuts up tight to the underside of the machine so that they will not move. Ideally the rear feet should also be locked.
If this has not cured the problem it is possible that the internal drum suspension is malfunctioning but I've not had any feedback of this nature.
If your washing machine will not fill, only hot or cold will fill or is slow to
fill then read these tips. I have covered many of the things that can happen in
these tips…
Check that it is actually heating the water. If it is not, I would suspect the heating element needs replacement.
It is programmed to fill with water - then heat it before washing.
If the water does not heat, it will just wait....and wait.
Leveling: Ensure the washer is properly leveled. An unbalanced load can trigger the UL (unbalanced load) code. Use a level to check if the machine is sitting evenly on the floor.
Load Distribution: Make sure the clothes are evenly distributed in the drum. An imbalanced load can cause the UL code to appear.
Calibration: Some models have a calibration mode that can be accessed through the control panel. Running a calibration cycle might help the washer to detect load balance more accurately.
Electronics: There could be an issue with the control board or wiring harness. Inspect these components for any visible damage or loose connections.
Professional Service: If none of the above steps resolve the issue, it may be time to consult with a professional appliance repair technician who can diagnose and fix the problem more accurately. They may have specialized tools and knowledge to pinpoint the exact cause of the UL code.
Ld is long drain, so either the pump is blocked, the pump impeller is worn or the drain hose is blocked.
I had a drain blockage on a Miele and it was cause by an apple stalk lodging itself across the ridges of the drain hose and had collected enough lint to block it, This was a machine that was washing towels commercially for 16 hours a day.
Unhook the drain and watch it pumping either into a bucket or into a laundry sink. It should fly out in a jet!

If yours is a top loader it will mounted near the drum inside the machine. It will be a shaped block of concrete curved to sit close the actual drum. The most like places will be at the front, nearest you when your putting clothes in it, at about 3/4 of the way off the floor. It could also be in a similar place at the back of the machine.
Unfortunately, if you can't get to it, you need a new machine. Normally you would seal with silicone or epoxy putty. The only thing I can can think of is injecting polyurethane expanding foam into the area, but go easy it expands for 10 minutes and you would have to shield any moving parts.
Most parts are obsolete.
