My washer won't turn on

That sounds like the pump is jammed and did not pump all the water out.

If your pump had something in it, it wouldn't have had to clog it, but rather just stopped the internal spinning. My coworker removed a dollar bill from his water pump, and it fixed the problem he was having (same as you've described) and the water pump worked well after it was re-installed.
Worst case scenario, you reinstall it and it doesn't drain and you spend 40 or 50 bucks online for the part. I would reinstall and see if it works. I'd bet on it.

I am not sure if Bosch has a "load sensing" sensor, but I would start there else you may have a motor issue, or bad capacitor on your motor.

If the machine didnt finish the cycle due to the pump being clogged the door will remained locked also if the lock mechanism went bad, the machine will stay locked. Remove the top of the machine by taking the screws from the top back out. Once removed look down the right hand side and you'll see the lock mechanism, usually with a plastic tab you pull to manually release the lock. On some machines it maybe be required and sometimes easier to remove the bottom kickplate and access the lock assembly from there

remove 4 screws on the rear panel and then remove the cover, you can see the drain pump remove both hoses on the pump,it is probably plugged up,if it is they wont drain or do anything

first check the house breaker and make sure you still have power. If it does then I would unplug the machine and lean it back against the wall to look at the motor wiring harness underneath to see if it came loose or is wet.

check the brushes on you motor

Hi, if clothes are wet after spinning, check.......
Motor coupler To test the motor coupler, re-start the washer in its spin cycle. Let the machine run for a minute, and then open the lid and notice whether the tub is spinning: If it's spinning when you lift the lid, the coupler is fine. If it isn't spinning--and your machine was produced by Whirlpool you may have a broken coupler. Many Whirlpool-made washers use a small, relatively inexpensive device called a motor coupling. This plastic-and-rubber component is mounted to the shaft of the motor on one side, and to the transmission on the other. Over time, the coupler wears out and fails. When that happens, you need to replace it completely.

Spin cycle If the washer doesn't reach its proper spin speed, the clothes may be too wet at the end of a cycle. Check to be sure the load is properly balanced and run a spin cycle again. If the clothes are still wet, you may have a worn or loose belt (Maytag), a worn clutch (GE/Hotpoint), or a worn motor pulley or tub bearing. Replace the applicable component. Alternatively, there could be clothes caught between the inner and outer tubs. Read the "It spins but won't pump" section of the "It won't drain" section. Also, there could be other things that cause friction on the drive train. Seek the assistance of a qualified appliance repair technician.

Siphoning If the water that pumps from the machine goes right back into the machine after the spin cycle, it may be because your washer is siphoning the water from a laundry tub with a slow drain, back into the washer. Try to improve the draining of the laundry tub. (Is there something stuck in the drain?) Also, be sure the drain hose doesn't reach more than about 4 inches into the laundry tub. If it does, cut off the excess.

Water-inlet valve Water-inlet valves eventually fail. One problem that may develop with a water-inlet valve is that it can no longer completely shut off when the electricity is turned off to it. Then, the valve may leak and drip water into the clothes tub--you may notice that your washer has water in it when you haven't used it for a few days. To fix this, replace the valve.

tub was out of balance remove some of the heavier clothing and re spin! and in the future donlt try to run so much through it that are heavier items when they are wet

sounds like drain is plugged. this is a fairly easy fix,and you actually get paid to do it. unscrew the bottom panel of your washer should be 3 screws on the very bottom then you will see a white plug that is about 2 1/2" unscrew it (make sure you have a bowl under it water will leak ) and pull it out. this is where you get paid you will find all kinds of change and junk just clean it out reinstall and your clothes will be a lot drier after the spin cycle
