10 Ways to Fix Your Hot Tub

Hot tubs are not only a great way to relax, but they’re also an important part of your family’s fun time. However, when a hot water tub has a problem, the moments of enjoyment can be abruptly interrupted. To help you deal with these issues, this article will dive into common hot tub problems and their solutions, providing a comprehensive troubleshooting guide for everything from a spa hot tub that doesn’t work to jets that don’t work.

1. Spa Not Working

Power Problems

If your spa hot tub isn’t working at all, first check that the power is connected properly. Make sure the plugs are plugged in tightly and that the electrical outlet is working properly. If the power is working, then check that the spa’s power switch is turned on. If these are all OK, you may need to check the spa’s fuse or circuit breaker.

GFCI Has Tripped

The GFCI (Residual Current Circuit Interrupter) is an important device that protects you from electric shock. If it trips, the spa hot tub will stop working. Check to see if the GFCI has tripped, and try to reset it. If the GFCI keeps tripping, there may be a problem inside the device, so call a professional to check it out.

The heater's upper limit thermostat is tripped

The heater's upper limit thermostat is a safety device that prevents the water from getting too hot. If it trips, the spa will not heat up. You can try to manually reset the thermostat, but if the problem happens frequently, you'll need to check that the heater is working properly.

Spa Lock is Activated

Some hot water tubs have a "spa lock" feature that prevents unauthorized use. If the spa lock is activated, the spa will not start. Check your owner's manual to find out how to disable this feature.

2. The spa will not heat up even when the jets and lights are running

The integrated pressure switch is on

If the spa's jets and lights are working properly, but the water is not heating up, it may be that the integrated pressure switch is tripped. This switch is used to detect water flow and shut off the heater if the flow is insufficient. Check the water level in the spa to make sure the water is flowing properly. If the water level is too low or the filter is clogged, this problem may be caused.

The circulating pump's thermal cutoff is tripped

The circulating pump's thermal cutoff is used to protect the pump from overheating damage. If the pump's temperature gets too high, the device will trip, causing the spa to not heat up. Check the circulating pump's ventilation and cooling to make sure it is functioning properly. If the problem persists, the pump or thermal cutoff may need to be replaced.

3. Weak or surging jet operation

The spa water level is too low

Weak or surging jet operation is usually related to the water level in the spa. If the water level is too low, the pump will not be able to effectively push the water flow, resulting in erratic jet operation. Make sure the water level is within the recommended range and add water regularly to maintain the proper water level.

Clogged filter

The main function of the filter is to remove impurities and dirt from the water to ensure smooth water flow. If the filter is clogged, the water flow will be hindered, resulting in weak jet operation. Clean or replace the filter regularly to ensure that it is in good condition.

4. Light does not work

Spa lock is activated

If the light in the spa fails to light up, it may be that the spa lock function has been activated. Check if any lock function is turned on and try to unlock it.

Faulty light wiring or components

If the light wiring or components are faulty, it will also cause the light to not work properly. Check if the bulb needs to be replaced or if the light connection wire is loose. If you cannot solve it yourself, it is recommended to contact a professional repairman.

5. Injectors not working or erratic

Clogged filter

One common reason why the injectors are not working or erratic is a clogged filter. A clogged filter can cause water flow to be blocked, which in turn affects the operation of the injectors. Check and clean the filter regularly to ensure smooth water flow.

6. Blue logo "Power" indicator flashes

The upper limit thermostat of the heater has tripped

The flashing blue logo "Power" indicator usually means that the upper limit thermostat of the heater has tripped. At this time, you need to check the temperature setting of the spa and make sure that the heater is not overloaded. If the thermostat trips frequently, it is recommended to contact a professional for inspection and repair.

7. Green logo "Ready" indicator flashes

Problem with temperature sensor

The flashing green logo "Ready" indicator may indicate a problem with the temperature sensor. The temperature sensor is responsible for monitoring the water temperature and ensuring that the heater is working properly. If the sensor fails, the spa hot tub may not maintain the set temperature. It is recommended to check the sensor connection or replace the sensor.

8. The control touch screen is turned on but cannot be operated

The remote control is too far away from the spa

If the control touch screen is turned on but cannot be operated, it may be because the remote control is too far away from the spa. Make sure the remote control is within the effective range and try again.

Communication Lost Between Control System and Remote Control

The touchscreen may also become inoperable if communication between the control system and the remote control is lost. Check the communication signal to make sure the connection between the two is stable. If the problem persists, you may need to reset the system or replace the remote control.

9. Control Touchscreen Is Off and Black Screen

Power to the Spa Is Off

The control touchscreen is off and black screen may mean that the power to the spa hot tub is off. Check the power connections and make sure the power switch is on. If the power is OK but the touchscreen is still unresponsive, you may need to check the touchscreen's connections or components.

Battery Needs Charging

The touchscreen may rely on an internal battery for power. If the battery is depleted, the touchscreen will not function properly. Try charging the battery and restarting the touchscreen.

Battery Is in Shutdown Mode

Some touchscreens automatically go into shutdown mode when the battery is too low to save energy. If the touchscreen will not power on, it may be because the battery has gone into shutdown mode. Recharging should restore normal functionality.

Battery Not Charging

The touchscreen will not function properly if the battery is not charging. Check the charger and battery connections to make sure they are in working order.

10. The touchscreen continues to display "Searching for spa" on a black screen

The remote control is not paired with the control panel

If the touchscreen continues to display "Searching for spa" on a black screen, it may be because the remote control is not paired with the control panel. Try re-pairing the remote control and control panel to ensure that they are communicating properly. If the problem is not resolved, you may need to check the connection of the device or contact a professional repair technician.
