Hi,
I'm from the UK, but on the off chance you are reading this over the weekend and have any ideas I thought I'd try my luck.
I have 4x 6550's on a 15000l display tank.
Fortunate that it is still fresh water, but was hoping to add salt today.
The pumps have been running for the last week no issue. I purchased a 7097 controller and connected it up last night. Within an hour only one pump was working.
I have a light on the PSU's I've tried moving the power supplies between the working pump.
I've left them disconnected from the power and controller over night, connected them to power without the controller this morning and still no joy.
Connected to an old 7095 controller and still nothing.
If it was just the one pump I could put it down to bad luck, 3 out of 4 has me very worried.
Is there some sort of factory reset I can do on the pumps? It's like they think they are blocked or something
Any help would be greatly appreciated
