SuperMarin 200 - Error F8 Air-Feeding error skimmer

Gravitys · 09/18/2019, 01:39 PM

I've got the F8 error for a while now.
I have checked from air filter down to the pump, unplugged and let the "air" parts in the vinegar, there is no salt anywhere, but still F8.

Any direction ?
Regards

So there is no buildup in the venturi port where the hose connects to the pumps nozzle like in the picture below? I clean my nozzle once a month or so using a small pick to remove the salt or calcium buildup from that port. I know you said you soaked it in vinegar but did you take the pump completely apart (impeller out) before doing so? The only things that typically cause the F8 would be an air restriction of some sort whether the venturi port is plugged up or restricted where the hose connects at the pump, the silicone hose being pinched due to the wedge pipe orientation, extending the air intake to outside out such as through a window or some buildup inside the pump and most particularly, where the impeller shaft seats into the back of the motor. Thus taking the pump completely apart and then a quick soak in vinegar followed by a scrubbing inside the motor block and on the impeller. Also, what speed/wattage do you have the pump running at?

Typical excessive salt and calcium buildup in the Venturi port and the #1 cause of the F8 error!

A closeup of the buildup!

thank you for the quick answer ! i have found i had salt in the middle of the air tube, there is a red connector rely both the two transparent tube, it was very thin, but apparently it did solve the issue !
