Help with 9410 DC Skimmer

[Lumensof13]

I have a 9410 DC skimmer which has been running for about a year with no issues. Last night it stopped working. The dial on the controller is blinking blue. There are no obstructions in the air line. I removed the impeller from the pump and cleaned it. There did not seem to be any obstructions. It turns freely by hand. When I put it back together and power it up, The impeller moves slightly then stops and the dial on the controller goes back to blinking blue. Any help would be greatly appreciated.

Hi, I replied to an email from you yesterday-

The two most important things that can cause this, the impeller is a magnet/needlewheel and shaft as one unit, these spin in ceramic sleeves in silicon rubber grommets. These sleeves must not be stuck to the shaft, the shaft must spin freely in these sleeves, if they cement together from calcium deposition and lack of service, the pump will only run by dragging the bushings and this will result in stoppage and damage. These bushing must be firmly seated, one down in a socket in the motor and one in the impeller cover. They have to be seated before installing the impeller and should only come out with effort and a tool is typically needed like a pick tool.

The other issue could be the intake on the pump is blocked, over time the air intake will plug with salt, either of these issues will increase the energy consumption and trip this safety shut down. Please check these two causes and reply with serial number and copy of the receipt if these do not solve it.

In this case, if you could PM me the info.
