Fills with water then does not rotate, also does not spin

Check for large items of clothes being tangled if the Bosch washing machine doesn't spin. The weight could not be evenly distributed in the drum and the spin cycle will have been disabled to prevent damage to the clothes..

Load the drum with large and small clothes together and run the entire washing cycle and spin cycle again.

Add more powder and run the entire washing and spin cycle again if you haven't found tangled large items, but the spin cycle still failed. This indicates the amount of cloths was too small.

Add 1 tablespoon of fabric softener to 1 pint of water and pour it into the main detergent dispenser if there's no tangling and the load was a normal size. The cause would have been excessive suds because of too much, or the wrong kind, of detergent. Use HE (High Efficiency) detergent in Bosch washing machines.
