Prr Flow Chart
If Prr error condition occurs (potential regulation sensor problem), follow
Troubleshooting Flow Chart below to identify the problem:
Replace board if
problem persists.
Note that water temperature
must be over 35
°
F to operate spa.
In systems manufactured after 98,
Prr error status is ignored during first
hour after initial power up to allow
water to heat to over 35
°
F.
Check if regulation
probe is properly connected.
Replace probe with
a spare and verify if
problem is solved.
If it is, replace
probe with spare.
Unplug probe connector
and clean pins on the
board (even a small coating
of film may cause a bad
connection).
Reconnect the probe.
Pressing any key after each step resets the system.
