Just after quaranty my machine stopped working. Looks like the locker doesn't send a signal to start. Filter is clean, display works and even for a moment washer was active (during switching off)

Is there a number associated with the "F" display? Usually when the washer displays anything with an "F" it has generated a fault code. But, it will usually have a number or another set of letters associated with it indicating what area of the washer has generated the problem. If you could double-check and provide more info I might be able to lead you in the right direction.

PREPARE
Step 1: Make sure you have 48 ounces of white vinegar on hand. You will also need an empty sink and a ceramic mug (do not use a paper cup.)
Step 2: Empty the water in the Water Reservoir b. FILL AND CLEAN
Step 1: Pour the vinegar into the Water Reservoir and fill it to the top edge of the clear viewing area.
Step 2: Place a ceramic cup in the Drip Tray and run a brew cycle. DO NOT USE A K-CUP…just press the Large Cup Button. Pour the contents of the cup into the sink.
Step 3: Repeat the brew process until the Water Reservoir is empty, pouring the contents of the cup into the sink after each cycle. Remember to open and close the lid between each cycle.
Step 4: Now fill reservoir with fresh water and let the Brewer stand for 4 hours while still on.
Step 5: Rinse the Water Reservoir thoroughly and fill with fresh water. c. RINSE Step 1: Ensure the Water Reservoir is filled with fresh water.
Step 2: Place a ceramic cup on the Drip Tray and run a regular brew cycle. Pour the contents of the cup into the sink.
Step 3: Repeat the brew process until the Water Reservoir is empty. Step 4: You may need to perform additional brew cycles if you notice any residual taste.

Regular cleaning (de-scaling) will prolong the life of the appliance. Scale is harmless, but left unattended, it can hinder optimal Brewer performance. De-scaling your Brewer regularly helps maintain the heating element, water reservoir and other parts of the Brewer that come in contact with water. Better water quality and water heating means a better cup of coffee. We recommend de-scaling your Brewer at least every 6 months (every three months if you are using hard water). The descaling process involves using 48 ounces of undiluted white vinegar.

Regular cleaning of the Brewer’s external components is recommended for proper operation. We recommend cleaning with a soapy, damp non-abrasive cloth. The K-Cup holder and funnel, drip plate, drip tray and removable water reservoir (on the Elite B40, Special Edition B60, and Platinum B70) are dishwasher safe. NOTE: the removable lid of the water reservoir is NOT dishwasher safe. The brewer should be descaled every 3-6 months.

Yes this is an issue on many Chevys with no recall. MOST of the time the problem you are describing is the wiper motor "pulse board", not the motor itself. Bad solder joints in the thin board, crack, so vibration and normal driving make them worse, and no contact is being made. Good news...Advance Auto Parts carries these for approx. $30, much cheaper than motor replacement. Just like wiper motor removal but all you have to do is remove (3) screws holding pulse board on motor housing, and most IMPORTANT, always put a thin bead of silicone or quality sealer around edge before re-install, this helps with vibration as well as waterproofing. Hope this helps!

Check the water pump for an obstruction in the chamber area, your pump may be sticking and that will cause the buzzing sound. The water pump runs during the fill portion of the cycle on several of the selected wash cycles to recirculate the water.

SOURCE: UL Code

Solved the unbalanced problem - open the top of the machine (press in with a flat putty knife about 3" in on the front on each side while lifting up as there are 2- 1" wide catches). Once both sides are unlatched, raise the lid then slightly lift the rear of the lid so that it fits into the curved part at the top of the hinges then open all the way - tape the lid to the top so it doesn't flap about and scotch the lid to keep it from falling back down on you. Now, look around - see all that rust?  The rust has fallen into and gotten underneath one or more of the 4 white plastic suspension "ball joints" which have probably totally dried out by now from their factory grease because of the water, bleach, and rust particles.  Having someone help you, simply lift up on one of the 4 corner suspension rods - gravity and weight is all that holds them down. The white ball will lift out of the socket and still be attached to the rod. Clean out the rust, lightly sand the "socket" with emery cloth, then slop in a fingerful of grease. I used automotive wheel bearing grease with graphite in it. Also scrub off all embedded rust on the white plastic ball. Lower that corner back into the newly cleaned and greased socket and repeat for the other 3 corners. Now when you move the tub around notice how the balls pivot in their sockets like they are supposed to. When they were dry and rusty they wouldn't move enough to allow the tub to twist like it should so it slammed around.  Now, shake your head in disgust that after only 2 years there is so much rust that you wonder if it will make it another year before falling apart, close the lid, and try another load.  That totally solved my off-balance problem where even a single handkerchief would give the UL error. It is still a finicky machine, but at least once again works like it did when new.
