This question has been answered so many times before. Machine will not spin while still full of water. Drum must drain all water out before the controller will start the spin cycle. Lid does not lock until the spin cycle starts. Put machine on final spin & press start. You will hear a humming noise down below. That is the drain pump trying to go but can't because it has a blockage. Very simple diagnostics really. Unblock the pump & problem solved.
