Pump 2 Does Not Work!
If Pump 2 is not working, carry out the following tests to correct the
problem:
To increase the life of the relay, we use a "snubber" circuit on the pump relay.
With this type of circuit, if no pump is connected to an output and relays are open,
the voltmeter will get a reading of around 60 volts. This is normal.
It is important to measure voltage when pump is connected to the pack.
Power must remain On.
2• Verify if "Pump 2" indicator appears
on keypad display when you press
Pump 2 key.
If "Pump 2" indicator does not ap-
pear, check low level programming
first (see Low Level Section).
4• If "Pump 2" indicator appears on
the display when you press Pump 2
key, verify if Pump 2 works in any
speed.
1• Check for any error condition on
keypad display. If there are, refer
to specific section indicated by the
error condition.
"Pump 2" indicator
3• If "Pump 2" indicator does not
appear, use a spare keypad to
verify if spa keypad is defective.
If it is, replace keypad.
If not, replace board.
