Table 4. SPA LCD Error Codes
Error Codes
Every SPA is subjected to an exhaustive battery of
operational checks and tests prior to its shipment. Oc-
casionally, however, units can sustain damage getting
from the factory to the user.
As a safeguard, the unit is equipped with a full set of
internal diagnostics that check operation and con-
figuration on power-up. If there are problems with the
microprocessor, or with conflicting operating parameter
settings, the LCD will show an error code upon unit
start-up.
Table 4 lists the error codes.
For most of these problems, it will be necessary to
return the offending SPA to the factory.
