Report "I have a Beko DWD8650x dishwasher, about 4 years old. It makes a lot of noise when you begin any programme. This lasts about 15mins until the machine fills with water - I think. Spray arms turn but seems to be less water in machine than I remember. Items in top drawer look exactly as they did going in. Have striped for blockage - none found in tubes or arms. Filters cleaned reguarly. Any ideas?"
