The flashing on/off light in a Jacuzzi whirlpool bath may indicate an issue with the control system, and it's important to address the problem to ensure the proper functioning and safety of the whirlpool bath. Here are some general steps you can take to troubleshoot the issue:
1. Check the Power Supply:
- Ensure that the whirlpool bath is receiving power. Verify that the circuit breaker for the whirlpool bath is not tripped, and check for any loose or disconnected power cords.
2. Inspect the Control Panel:
- Examine the control panel for any visible issues, such as loose or damaged wires, connectors, or buttons. Ensure that there is no water or moisture present in the control panel area.
3. Reset the System:
- Some whirlpool baths have a reset function. Turn off the power to the unit, wait for a few minutes, and then turn it back on. This can sometimes reset the control system.
4. Refer to the User Manual:
- Check the user manual that came with your Jacuzzi whirlpool bath for specific information on troubleshooting and resetting the control system. The manual may provide insights into the meaning of the flashing light and how to address it.
5. Contact Jacuzzi Customer Support:
- If the issue persists and you cannot find a resolution through the manual, contact Jacuzzi customer support or the manufacturer for assistance. They may be able to provide guidance on how to troubleshoot and resolve the issue.
6. Professional Inspection:
- If you're not comfortable or able to identify and fix the issue, it's advisable to seek assistance from a qualified professional or a technician experienced in Jacuzzi whirlpool bath systems. They can perform a thorough inspection and diagnose and repair any electrical or control system problems.
It's essential to prioritize safety and follow proper procedures when dealing with electrical components and water. If you're uncertain or if the troubleshooting steps don't resolve the issue, it's best to seek professional assistance to avoid potential hazards.

If you turn the Jacuzzi pump on and it just hums and no water flows through the jets then you have a bad pump.
You will need to get the brand name of the pump and the model number before you can begin your search to find the proper replacement.
Bath Pumps each have their own size. You will want to find the exact brand so you do not have to change any of the plumbing.

The air button on your tub may be bad and not sending enough air to the air switch located on the bath pump.
The way to check this is to remove the bath pump and see if you can turn the bath pump on by taking a large straw and blowing into the air switch on the bath pump to see if you can get the bath pump to turn on.
If the bath pump comes on then you know you have a bad air button.
If you cannot get the bath pump to turn on then remove the air switch and plug the two wires going to the air switch together and then plugging the pump into a power outlet you know has power.
If the bath pump comes on then you know you need a new air switch in the motor.
If the motor does not come on then you need a new bath pump.

I assume you hooked the hose back up to the air switch on the motor.
There will only be a couple of things to check.
Make sure you have a good connection with the air hose to the air switch on the motor. Sounds like maybe the air switch may be bad.
The Air Switch is a latching air switch so if is broken then it won't latch when the air button is pushed.

sounds like you need a new temp sensor on your tub. if it is not heating and running all the time even though it is calling for heat - then the sensor is bad.

you can find a sensor here Bath Parts Plus

get an electrician. you need to follow the code for the size of wire to use based on number of amps of the motor and how far away the pump is from the power outlet.
