Bosch SHE4AP won't drain

Hi. The usual dishwasher won’t drain topic, but for a newer model. Installed less thn 6 months ago. Won’t drain water out. Have used the SHU service manual to do diagnotic tests on it. The drain pump spins at the beginning of the diagnostic test, the washer fills with water, but then, drain pump won’t spin to remove the water and fails. Could it have something to do with the dirty water sensor thing in the drain? The pump seems to not spin when there is a lot of water in the washer, like above the filer screen. I removed the drain hose from the pump itself, and when it drains at the beginning of the test, the water doesn’t fly out real fast. Sort of dribbles out the pump.
