Problem solutions
potential
freeze-up
conditions
If the possibility of potential freeze-up is detected, or the AUX freeze
switch is off and all pumps and blower are activated. In some cases,
the pumps may turn on and off and the heater may run during freeze
protection mode. This is an operational message, not indication of failure.
M029
The water is too hot
One of the temperature sensors has detected a water temperature of
109.94 °F and the hot tub functions are blocked. The system automatically
resets when the water temperature is below 107.96 °F. Check that the
pump has not been running for too long, or that the ambient temperature
is not too high.
M016
Water flow through the heater is reduced
This message indicates that not enough water is flowing through the
heater to distribute heat away from the heater. The heater starts again
after about 1 minute. See below “Relevant flow inspections”.
M017
Water flow through the heater failed
This message indicates that not enough water is flowing through the
heater to distribute heat away from the heater, so the heater was
disconnected. See below “Relevant flow inspections”. After the problem
has been resolved, press any button to reset and turn on the heater again.
M028
There seems to be no water flowing through the heater
There is no water or very little water in the heater, and the heater cannot
turn on. The hot tub switches off for 15 minutes. Press any button to
restart the heater. See below “Relevant flow inspections”.
M027
The heater has no water flow
There is not enough water in the heater for it to start. The hot tub is
switched off. After the problem is resolved, press any button to reset
and restart the heater. See below “Relevant flow inspections”.
M030
The heater is too hot
One of the temperature sensors has detected a temperature of 118.04 °F
in the heater and the hot tub is switched off. Press any reset button when
the water reaches a temperature below 107.96 °F. See “Relevant flow
inspections” below.
