Bosch Axxis front loader will not drain

Our 3.5-year-old Bosch Axxis washer won't drain or spin. The wash cycle (regular cotton, cold or warm) proceeds as far as rinse/spin then stops cold, and the finish light flashes. Have tried re-setting the selector to Off for 2 minutes then setting it to spin, but get only an electronic buzz when I push the Start button. Attempts to start the whole cycle from the beginning repeat the problem: stops at rinse/drain/spin. Machine was moved recently so the room could be painted but was handled carefully.

Check filter. check no foreign objects fouling pump impellor - bra wires are the favourite

Where is filter in front loader
