Diagnosing M7 Topside Control Panels
PRELIMINARY PANEL CHECK
If the problem is not obvious, look on the topside control UÊ
panel for diagnostic messages.
If no messages are seen, run through all spa functions
and note any inconsistent operation.
Most error messages are stored in the fault log. To view
UÊ
the fault log, the spa must be in test mode and the spa
light must be turned on.
Once you have determined that proper voltage is running
through the circuit board and transformer, continue to the
topside control panel. A panel that is not functioning properly
may include the following symptoms: low voltage such as
missing or scrambled segments, missing icons on the LCD,
non-functional LED’s, or nonfunctional buttons. If any of these
symptoms are present, perform the following:
Turn the power off and unplug the panel from the UÊ
circuit board.
Then, plug in your test panel and restore power. If every-
UÊ
thing functions normally, replace the topside panel.
Disconnect ozone generator (if applicable).
UÊ
If you still see symptoms of low voltage, such as a UÊ
sluggish, blank or partially blank panel, or if the display
or the LED’s do not function at all, turn the power off;
unplug the ozone generator (if equipped); then restore
power to the system. If the problem persists, turn off the
power and replace the circuit board.
PANEL DISPLAY MESSAGES
THE PANEL DISPLAYS:
, , or
At least one of the sensors has detected water temperatures
of 118ºF inside the heater. Or,
THE PANEL DISPLAYS:
, , or
One of the sensors has detected the temperature
of the water coming into the heater to be 110ºF,
and so the water in the spa is likely to be that hot.
These indicate that the spa has shut down due to an
overheat situation.
NOTE: Overheating may occur if the low-speed pump is set
to operate for extended periods of time, or if the incorrect
pump is installed. In rare cases (usually warmer climates), the
circulation pump may also cause overheating.
MOST PROBABLE OVERHEATING CAUSES,
INSPECT THESE FIRST
Check slice or ball valves. Make sure that they UÊ
are open.
Make sure the correct pump is installed.
UÊ
Clean the filter/skimmer if there is any blockage. UÊ
Check heater element alignment. UÊ
Check for debris on the heater element. UÊ
In extremely hot weather, check for proper UÊ
cabinet ventilation.
Make sure the temperature sensor is fully inserted
UÊ
into the sensor fitting on the heater.
Check for excessive filter duration.

Panel messages are a quick clue toward solving a variety of problems. Here are the most common messages and what
they mean.
