Beko bean to cup coffee machine (Yatton BS49)

Well used and enjoyed bean to cup coffee machine with milk frother. Can be used for tea and hot chocolate too. A couple of years old. However, it has started overgrinding which eventually blocks the machine. Have tried descaling again (although I was descaling regularly anyway) and gave it a thorough clean but it’s happened again. If anyone would like to have a go at fixing it, you are very welcome to have it!
