Problem with a Stream 6000

[Stevenx2]

Hi!

Here's my set-up:
95G Tank
2 Stream 6000
1 7095 multicontroller
1 Electronic 7400

Here's the problem:
I am using the interval #2 (high-/low-tide simulation), only the stream 6000s are linked up.
When pump Nr. 1 is off and Nr. 2 is running, Nr. 1 makes these weird "click" noises every 30-60 seconds. I then looked a little closer at the pump and noticed that with every "click" the rotor turns 1/4 or 1/2 the way. The pump has been doing this since a couple of days. When the tides turn, and pump Nr. 1 is running, it runs fine (doesn't make any "click" sounds). Pump Nr. 2 never "clicks" when off or on.

Any idea what this could be?

Thanks in advance!
-Steven

Pump Number 1 has the new driver 7240.27, what you are describing is the "fishcare" feature designed to scare away fish so they don't go in the pump when it is off. The other one must be older and have the 7240.26 driver.

Thanks for the fast answer! I was worried that it could be broken!

Thanks again!
