This guide provides non-technical troubleshooting steps for common problems you might encounter with your Cal Spa. It's designed to help you identify and resolve issues yourself, potentially saving you the cost of a service call. The information presented here does not require tools and will not void your warranty. However, this guide cannot resolve every possible spa problem, and it focuses primarily on control panels built in 2013 and earlier. For issues beyond the scope of this guide, or if your spa is still under warranty, scheduling professional service is always recommended, particularly for wearable parts like jet inserts and lights.
Understanding Error Codes
Cal Spas utilize message codes on the control panel to communicate potential problems. These codes can provide valuable clues for diagnosing issues. This guide will cover some of the most common codes and their corresponding troubleshooting steps.
Common Problems and Solutions
1. "Insufficient Water Detected in Heater"
This message indicates that the water level in the spa is too low, or there is insufficient water flow.
Troubleshooting Steps:
- Check Water Level: Ensure the water level is at the recommended level. Refill the spa if necessary.
- Clean Filters: Make sure the filter cartridges are clean. Dirty filters restrict water flow.
- Reset the Spa: After checking the water level and cleaning the filters, reset the spa. In some cases, the spa will automatically reset itself.
Persistent Low Flow:
If other spa functions continue to run normally despite the error message, follow the actions required for "HL" or "HFL" messages (see below). If the problem is persistent, it may require further investigation.
2. "HL" or "HFL" (Overheat Protection)
This code signifies that the spa has shut down due to overheat protection.
WARNING: DO NOT ENTER THE WATER if this message is displayed.## Troubleshooting Steps:
- Allow Water to Cool: Let the water cool down to a safe temperature.
- Reset the Spa: Once the water has cooled, reset the spa.
If the problem persists after resetting, contact customer service for assistance. The capacity of the spa will not reset automatically.
3. "Sensors are out of Balance"
When you see the error message "Sensors are out of balance" (possibly blinking), the spa is shut down. Water temperature is unknown.
Troubleshooting Steps:
- Reset the Spa: Reset the spa.
- Restart the Spa: Restart the spa.
4. Spa Not Heating
One common scenario involves the spa turning on, the heating light illuminating, but the water not heating. Here's a breakdown of potential causes and troubleshooting based on a real-world experience:
Scenario:
A spa owner with a 2006 Cal Spa hot tub found their tub cool after returning from vacation. The breaker had tripped. After resetting it, the tub would run for about 30 seconds before tripping again, displaying "IC" and a temperature of 67 degrees.
Troubleshooting Steps:
- Check the Breaker: A tripped breaker is often the first sign of an electrical issue. Reset the breaker and observe if it trips again.
- Remove Filters: Removing the filters can help determine if a clogged filter is causing the issue. If the spa runs without the filters, clean or replace them.
- Check Voltage to Heater: Use a multimeter to check the voltage at the heater terminals. In the example case, the owner found 240 volts were present, but there was no amperage.
Potential Causes and Solutions:
- Heating Element Failure: If the heater is receiving the correct voltage but drawing no current, the heating element is likely defective. An ohmmeter can confirm this. With the power off and the heating element disconnected, measure the resistance across the terminals. A typical reading is around 10 ohms. Also, check the resistance from each terminal to the metal housing; there should be no continuity.
- Circuit Board Issues: While a faulty circuit board can cause heating problems, it's less likely if the heater is receiving voltage. The circuit board's primary function is to send voltage to the heating element. If voltage is present, the board is likely functioning correctly.
Important Note: Before replacing any parts, consult with a qualified technician to ensure accurate diagnosis and prevent unnecessary expenses.
Cal Spas Pumps Priming (2013 and Earlier)
Cal Spas pumps built in 2013 and earlier have a unique priming method. Consult your owner's manual for specific instructions related to your model.
General Troubleshooting Tips
- Observe the Spa's Behavior: Pay close attention to how the spa is behaving before and after the problem occurs. Note any unusual noises, smells, or error messages.
- Keep Records: Maintain a record of any troubleshooting steps you take, including the date, time, and results. This information can be helpful if you need to contact customer service.
- Consult Your Owner's Manual: Your owner's manual is a valuable resource for troubleshooting specific problems. Refer to it for detailed instructions and diagrams.
- Safety First: Always disconnect the power to the spa before performing any maintenance or repairs.
