LTF2940ES2 won't do final spin

Make sure load is properly sorted with like materials and paired up, do not mix things like towels with pants or shirts all together as different items absorb more water then others and can create unbalance when trying to enter final spin. If issue continues, it is very possible and item of clothing may have found itself stuck between spin basket and outer tub. This is very likely scenario due to design of this washer. If that is the case, spin basket must be removed then remove clothing to resolve issues.

Sounds like corrosion in the motherboard . Get an electronics serviceman to take a look, could just need soldering point to point connection. Hope this helps.

If the unit does not spin correctly, this is usually an indication that the unit can also not drain. The unit will not spin if it senses a blockage or issue with the drain lines and/or pump. Try to check the drain lines in the back of the unit for any issue, and then see if you have an access panel to get to the coin trap or drain pump itself. Often socks and debris will clog up in this area and cause your problems.

What is the model number of your unit?

Either a blocked filter or worn carbon brushes

Unplug unit for 5 minutes to reset control board. If problem still persists, you will need to call a technician to service it.

Try this, unload the washer and put it into spin manually. If it spins for the whole cycle then it is your motor over heating, with the load.

It be the carbon brushes are worn down on the motor, when it goes into the final spin.

The final spin on this model requires an additional lock from the computer to the door. Remove upper rear panel and look at board. Find the tiny resistor that says R-11. If it's burnt looking the board and the wax motor (at the lock) need replaced
