美国采购需求：盐氯发生器系统、游泳池设备、盐氯发生器、盐氯发生器电解槽更换、盐水系统部件、泳池灯

I've tried two different new salt cells, but I'm still encountering an error on my blue works control panel. This ongoing issue has made me suspect that the control panel itself might be faulty. Could you please provide any insights or troubleshooting steps for addressing this problem? If you think I might need to consider a replacement for the panel or if there are specific tests I should perform, that would be really helpful. Looking forward to your guidance!
