I have the same model, BUT mine ends GB/01. Same problem as you. So unscrewed service flap (front bottom right) drained water, removed washing, unscrewed pump cap, found a small amount of debris, cleaned it up. Flipped machine onto its back unscrewed 8 retaining screws (underneath machine), removed black hose. Found 5p and 2p coin and, as we are in a hard water area, some moderate limescale. Cleaned it up & reconnected. Selected a wash programme, drum fills with water, but wash cycle won't contine after that point. Could hear small clicking noises as if programme trying to advance but it wont although display timer continues to count down. So flipped dial to spin, water is drained off, but spin cycle goes from 11 mins to zero. I know that the water inlet and outlet are clear, I'm trying to figure if the cycle control circiut board has packed up, but having probs searching for advice on the net.
