This seems to be a very strange "Assessment". There is nothing on or inside a front loader washing machine that contains Oil. The motor is also tucked inside the machine often where it is difficult to get to. There will be small amounts of grease on the drum and motor bearings but not enough to affect other machine parts. I would suggest you get a second opinion from another good repairer.
LG will claim that this damage was not due to a part failing so it will not be covered by a warranty or guarantee. This will be see as damage being done 'on purpose' so it's not their problem.
It sounds like there may be an issue with your LG washing machine. The "err" sign and lack of additional information make it difficult to determine the exact problem. Some possible causes could be a clogged drain, a malfunctioning water inlet valve, or a problem with the machine's control board. It's best to consult the user manual or contact LG customer service for further assistance in troubleshooting the issue.
The "PF" error code on an LG washing machine typically indicates a power failure. This can be caused by a power outage, a tripped circuit breaker, or a problem with the electrical outlet or wiring.
Check the drain hose position if you hear the water go to the drain. If the drain hose is positioned too deeply in your sink or stand pipe, you create a siphon that pulls the water out of the tub. Make sure that the end of the hose is above the highest water level in the washer tub. If the water is inside the washer cabinet, check for a damaged seal (washer) between the tub and the drain hose. (On some machines, there is a tub and an inner basket. The point where the spin motor connects to the basket has a bearing in addition to the seal. Both must be replaced. This is not easy and isn't generally worth the cost if the machine is out of warranty.)
Please add a comment with the model number of the washer (usually found on the rim of the tub), if you would like me to try and find the parts diagram for the LG washer.

Examine the gearbox; it can be the cause of the issue.
Examine it for damage, such as stripped gears or worn-out bearings, and repair it if required.
Examine the clutch assembly: The clutch assembly engages and disengages the transmission and drive motor.
Check to see if the clutch assembly is in good condition and not worn out.
Examine the drive belt: The drive belt turns the drum and links the motor to the transmission.
Verify that the drive belt is not slack, worn out, or damaged.
Check the tub bearings: The washer's drum is supported by the tub bearings.
The gear system may malfunction if the tub bearings are worn out.
Contact the manufacturer: If none of the above solutions work, it may be necessary to contact the manufacturer for further assistance. They can provide more detailed troubleshooting steps or recommend a service professional to diagnose the problem.
Load the items you want to soak into the washer drum.
Press the "Power" button to turn on the washer.
Press the "Pre Wash" button, this will start a pre-wash cycle that will last for 5 minutes, this will give you the time to add any detergent or laundry pre-treatment solution.
Press the "Start/Pause" button to start the pre-wash cycle.
Press the "Delay Start" button to set the time you want the washer to start the main cycle. This will give you the opportunity to soak the clothes overnight
Press the "Start/Pause" button again to start the main cycle after the pre-wash cycle is complete.
Leave the items in the washer overnight.
In the morning, press the "Start/Pause" button to start the main cycle again.
When the cycle is complete, unload the items from the washer and dry them as usual.
There are a few potential reasons why your LG Roboking robotic vacuum cleaner might be spinning:
Obstacle detection: The Roboking is equipped with sensors that detect obstacles in its path, and when it encounters something it cannot navigate around, it may spin in place.
Stuck on a cord or rug: The robotic vacuum cleaner may be stuck on a cord or rug and spinning in place as it tries to free itself.
Mechanical problem: The vacuum cleaner may have a mechanical problem such as a stuck wheel or other issue that is preventing it from moving forward.
Low battery: If the battery is low, the Roboking may spin in place to indicate that it needs to be recharged.
Software or firmware bug: The software or firmware of the roboking may have a bug that causes the vacuum cleaner to spin.
It's best to check if there's any obstacle or cord that is stuck to the roboking, if there's not, it might be a good idea to contact the manufacturer for assistance or have a professional technician to check it.
You can also check the software version and see if there's an update available.
There are a few other potential causes for slow water flow in a washing machine:
Clogged or partially clogged water inlet valve: The water inlet valve is responsible for controlling the flow of water into the washing machine. If it is clogged or partially clogged, it can cause a reduction in water flow.
Washing machine pump: The pump is responsible for moving water through the washing machine. If it is damaged or not functioning properly, it can cause a reduction in water flow.
Water supply hose: The hose that supplies water to the washing machine may be clogged or damaged, which could cause a reduction in water flow.
The washing machine itself: There could be an issue with the internal components of the washing machine that is causing the slow water flow.
If you have checked the filters, water pressure, and solenoid and they are all functioning properly, you may want to try checking the water inlet valve, pump, water supply hose, and the washing machine itself for any issues that could be causing the slow water flow.
Sounds defective. All in ones are a compromise. You would be better off with a stacked unit. Try kneeing it when it is doing it. See if it changes pitch.
There is a video here. They are normally a plastic plug with a rubber seal. You turn the handle in the centre which makes the rubber seal expand to seal the plug.

Please always include full model details. The manuals are normally online.

Question 3 also edited.
Slide a single sheet of newspaper under the machine. As the machine is running pull the paper out every 10 minutes and look for where the water has dripped. That will tell you the area where the leak is. When the machine has finished, pull the machine out and tilt it back against the wall. Have someone hold the machine whilst you look with a flashlight. It is likely to be the pump or any of the hoses. On a top loader it can be seals or corrosion. On a front loader a crack in the plastic outer drum.
Question 2 also edited for clarity, 'LG' not 'lg'.
No model details again.
Surely not during 'Rinse' cycle? That just adds water and gently tumbles to get the soap out and complete the washing by further agitating the clothes. You must mean during spinning and much depends on if it is a front loader, or a top loader. For both, machine not level front to back and left to right and / or not sitting firmly on all 4 feet.
Top loader, bulky load unevenly loaded.
Front loader, single bulky item causing an uneven load.
Question edited for clarity.
FULL 'make and MODEL' in all question please, first 3 words.
I see you have three questions on the go!
What does medic rinse mean on LG washing machine?"
MEDIC RINSE. This programme minimises detergent residue. It uses a high level rinse and warm (40° C) rinse.

This error means that the lid lock isn't engaging or the lock signal was not received by the control board. This could be because something blocked the lid from closing. Check for dirt or a piece of laundry in the latch area. (On some models of top-load washers the lock mechanism involves a small magnet. If this applies, check that the magnet hasn't fallen out.) Unplug the washer for a few minutes to reset the error code.
If the error persists, you'll need to check if the problem is the lock mechanism not moving freely or damaged/corroded wiring at the switch or at the control board or electronics of the switch. If the switch and wiring are okay, then the control board could be faulty.
I hope this helps. Please add a comment with the model number of the washer if you need help finding a parts list/diagram.
