The sentry timer on my Jacuzzi Duet II flashes 3 times and stops - we cannot get it to work

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.

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.

Sounds like a bad heating element. This is located in a stainless steel tube under or around the main control box behind the cover around the tub. It is not hard to replace but should be done by a pro. The part is avaliable online.
