I have a Tunze Stream. I think the model # is the 6000. It is run by a Turbelle driver 7240.27. Yesterday I heard a high pitch squeal coming out of the driver and noticed the Stream wasn't pushing any water. The lights on the single controller were all on and one was flickering. Any thoughts as to what is going on? Perhaps I need a new driver? What should I be checking or trying?
