Describe Your Bosch Appliances SHU9915UC12FD8003 Dishwasher Problem... Bosch Integra SHU 9955US/12 - when we start wash cycle, the detergent dispenses and the tub fills with water, but the wash cycle never starts (never spins spray bars). Seems like timer is counting down, though, but doesn't start "washing". After waiting awhile, we are able to use the "Cancel/Drain" mode to drain the water. The drain filter in the bottom of the tub is clean.
