The "All button" controller has "6700 REV C" displayed with all of the LED's on and with no control from the all button unit. The pump is running as it should with the proper on/off times. The wiring between the all button controller and PCB board is OK, even hooked the all button direct to the PCB with the same problem. This same problem happen about two months ago. I disconnected the four wires between the controller and the PCB, hooked them back up and everything was working. Looking at the PCB, I noticed there are two 'chips', one is the processor and the other I am not sure of. Could these be reseated??? Any help would be appreciate since this has been going on for a couple of weeks.
