Not delivering coffee and leaking clean water

My machine is grinding the beans, then goes through the motions to make coffee but at the point it would deliver coffee nothing happens you can hear a soun from the exit hole but nothing come out, then it froths and delivers the milk.the grounds are wet and hot but then water leaks from under the tray. The water is clean doesn’t look like it’s been through the beans. I’ve cleaned the brewing unit run descaling and coffee cleaning .
