CS7500/CS6500 - ERROR MESSAGES

PRESSURE or FLOW SWITCH ACTIVATED

 - This error is an indication the pressure or flow 

switch is not opening when the pump is off, the programming is not correct, or low level 
programming has just been done with the pump running.  

Confirm proper system programming and/or pressure switch calibration

Contact your local spa dealer

PRESSURE or FLOW SWITCH NOT ACTIVATED

 - This error is an indication the pressure or 

flow switch is not closing when the pump is on.  Check for dirty filter, proper water level and 
flow, if the error does not clear this is an indication that the pressure or flow switch may need to 
be adjusted or replaced. 

Contact your local spa dealer

TEMPERATURE SENSOR MALFUNCTION

 - This error will occur when a problem with the 

temperature sensor exists. This error may also occur if the system is activated while the water 
temperature is below 35°F.  

Contact your local spa dealer

OVERHEAT or HIGH-LIMIT PROTECTION

 - There are three (3) stages of over-temperture: 

1 - The spa water has exceeded 112°F. The heater, pump and accessory will be deactivated 
until the water cools to 109°F. 

Be sure to check the actual water temperature with an accurate 

thermometer. 

2 - The spa water has exceeded 119°F. The heater will deactivate while the pump and 
accessory will still operate. The blower (if equipped) can be activated to help cool the water. 
WATER MUST BE BELOW 119°F AND POWER MUST BE RESET TO CLEAR THE “HL” 
ERROR   

A dirty spa filter can also cause a restricted flow of water, be sure the filter is cleaned regularly 
and ensure all water shutoff valves are open.

If the system has been operating normally until now, the pump may be overheating the spa. 
Refer to “Programing Filtration” on page X and reduce the duration and/or number of cycles per 
day.

3 - If you’ve eliminated items 1 & 2 as problems, the high-limit sensor may have malfunctioned.   

Contact your local spa dealer

FREEZE PROTECTION:

SMART WINTER MODE:

  This mode will activate any time the ambient/outside temperature falls below 

59°F if required.  This mode will be active for a period of 24-hours. In this mode, if a pump has not 
been activated in the last 2 hours, the system will automatically turn it on for 1-minute every 2 hours to 
prevent freezing. The “Filter Cycle” indicator will flash while this mode is active.
