10 Error Messages and Diagnostics

This section describes all error messages that may appear on the TP500 panel display, with detailed explanations from the official Balboa manual and step-by-step troubleshooting instructions.

10.1 General Status Messages

10.1.1 RUN PMPS PURG AIR - Priming Mode (M019)

This message appears every time the system is powered. Priming mode allows you to manually run each pump to verify they are primed (air has been eliminated) and water is flowing correctly.

Priming mode characteristics:

• Duration: 4-5 minutes
• The heater is disabled during this phase for safety
• No devices activate automatically
• Pumps can be manually activated by pressing the JETS buttons

What to do:

1. When the message appears, press the JETS button once to start Pump 1 at low speed
2. Press again to switch to high speed
3. If a second pump is present, press AUX to activate it
4. Observe that water flows from the jets in the tub
5. If pumps do not deliver water after 2 minutes, turn them off and repeat the process

WARNING: Do not run a pump without water for more than 2 minutes. Repeat the priming attempt maximum 5 times. If pumps do not prime, turn off the system and contact service.

To manually exit Priming mode, press a temperature button (WARM or COOL).

10.1.2 ---°F / ---°C - Unknown Temperature

The display shows dashes instead of temperature when the system has not yet detected the water temperature.

What to do:

1. Wait for the pump to run for at least 1 minute
2. The system requires water moving through the heater to measure temperature
3. After about 1 minute of pump operation, the temperature will be displayed

10.1.3 TOO COLD - Freeze Protection

The temperature sensors in the heater have detected a potential freezing condition. Pumps and blower activate automatically to protect the system.

System behavior:

• All pumps and blower activate automatically
• They remain active for at least 4 minutes after the freeze condition has ceased
• Pumps may run continuously or intermittently depending on conditions
• The heater may activate during freeze protection

What to do:

1. No action required: the system manages protection automatically
2. Ensure the thermal cover is properly positioned
3. Never disconnect power during freezing conditions

WARNING: In cold climates, if the GFCI/RCD trips, it must be reset immediately to avoid freeze damage to the hot tub.

10.1.4 WATR TOO HOT - Water Too Hot (OHS - M029)

DANGER: One of the temperature sensors has detected that water has reached 43.3°C (110°F). All spa functions are disabled.

System behavior:

• The system resets automatically when temperature drops below 42.2°C (108°F)
• You can manually reset by pressing any button

What to do:

1. Do not enter the water under any circumstances
2. Remove the thermal cover to promote cooling
3. Check if there was prolonged pump operation
4. Check if ambient temperature is particularly high
5. Wait for temperature to drop below 42°C

10.1.5 SFTY TRIP - Safety Trip (M033)

The system has detected closure of the vacuum switch. This indicates a potential suction problem or an avoided entrapment situation.

WARNING: Not all systems have this safety feature.

What to do:

1. Do not enter the water
2. Check that suction grates are not obstructed
3. Check that no objects are blocked near the suctions
4. Contact service if the problem persists

10.2 Heater-Related Messages

10.2.1 HTR FLOW FAIL - Reduced Heater Flow (HFL - M016)

There may not be enough water flow through the heater to dissipate heat from the heating element. The system will attempt to restart the heater after approximately 1 minute.

What to do - Flow checks:

1. Check the water level in the tub
2. Check for flow restrictions at suctions
3. Check that all valves are open
4. Check that no air is trapped in the system
5. Check that not too many jets are closed
6. Check that the pump is properly primed

10.2.2 HTR FLOW FAIL (LF - M017) - Confirmed Insufficient Flow

Water flow through the heater is insufficient to dissipate heat. The heater has been disabled.

What to do:

1. Perform all flow checks described above
2. After resolving the problem, press any button to reset and restart the heater

10.2.3 HTR MAY BE DRY - WAIT (dr - M028)

WARNING: Possible dry heater, or there is not enough water in the heater to start it. The system shuts down for 15 minutes.

What to do:

1. Wait for the 15-minute automatic pause
2. Meanwhile, perform flow checks
3. Press any button to reset and restart

10.2.4 HTR DRY - Dry Heater (M027)

DANGER: There is not enough water in the heater to start it. The system has shut down completely.

What to do:

1. Immediately check the water level in the tub
2. If the level is low, fill to the correct level
3. Perform all flow checks
4. After resolving the problem, press any button to reset and restart

10.2.5 HTR TOO HOT - Heater Overheated (OHH - M030)

DANGER: One of the sensors has detected a temperature of 47.8°C (118°F) in the heater. The system has shut down completely.

What to do:

1. Do not touch the system
2. Wait for temperature to drop below 42.2°C (108°F)
3. Perform flow checks to identify the cause
4. Press any button to reset when temperature has dropped

NOTE: Even when the system is off, some devices may occasionally activate to monitor temperature or if freeze protection is needed.

10.2.6 PRES BTTN TO RSET - Press to Reset

This message may appear along with other error messages. It indicates that a button must be pressed to acknowledge the error and reset the system.

NOTE: Some errors may require disconnecting and reconnecting the power supply.
