How can I resolve "Low LED Error" on an APA6000?
APA 6000 Low LED Error
The "Low LED Error" is normally created by build up in the colorimeter cell. The first step is to ensure that the surfactact wash solution is full and not expired. Then from the Solutions and Cleaning menu, initiate the Auto-Clean as well as check that the cleaning interval is set (default 12 hours). If this cleaning is not successful, manual cleaning of the colorimeter via disassembly might be required.
