My on off button quit working on my bath jacuzzi. I can go out to the garage and trip the breaker to turn it off and on. I used to be able to barely push it and it would come on or go off, now you can push in about a half inch or better but it still doesn't turn it off/on when before you just barely had to push it. Can I fix this myself?

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.

The only place I'd expect to find a reset button is on the motor itself. That is, unless it's a ground fault problem, in which case it might be on another ground fault outlet somewhere in the house (possibly a bathroom or garage outlet) OR on the breaker - check the breaker box to see if the breaker's tripped or the GFE button needs to be reset.

Bad ground or faulty GFI plug.

if breaker is tripped your gonnahave to look inside the covering to see if you have a water leak, if not it's probally your heater, they do go bad, faster if your not dilagent on your water chemistry to be perfect

The threaded knob should not be related to the problem, it just controls how much air gets mixed into the water jets. One possibility is that the electricity is off. These tubs should receive power through a Ground Fault Circuit Interrupter (GFCI) type of circuit breaker for your protection from electrical shock. Check your circuit breaker panel(s) for a breaker with a little square white or yellow "test" button. Refer to the label (if it is there) to see if it refers to "tub" or "spa" or "bath" or something like that. You may have to turn the breaker handle off (push extra hard to make it reset) and then back on again. If the breaker handle is in the "on" position and the "test" button does not "trip it off," call an electrician. If no luck there, check the bathroom for an electrical outlet with GFCI protection, again looking for white or yellow (or red) buttons - one should be engraved "test" and the other "reset" as the electrician (I hope it was an electrician) may have supplied the tub from this outlet (not actually up to code). Plug an appliance or light into the outlet. If it doesn't work, push the reset button on the outlet and test again. If working, now test the spa. If that doesn't work, test every other GFCI outlet you can find - in the kitchen, other baths, garage, outdoors, basement, etc. using the same testing procedure. If you find a GFCI breaker or outlet "tripped" that restores the tub, that indicates there is something wrong with your electrical system that could cause you to get electrocuted, and requires that you hire a qualified electrician to investigate the problem. The same is true for any GFCI outlet that does not "trip" and/or "reset." If this doesn't fix the tub, the problem may not be electrical but some other problem with the system, indicating a plumber or spa tech may need to be consulted. Note: these GFCI breakers and outlets are supposed to be tested and reset once every month. How many of us do that? Well, at least as often as we test our smoke detectors, I suppose.

There are a couple things you can try with your tub.. The 10 min timer is one they used on older tubs but, may still be used with yours. Turn timer all the way up. make sure tub is filled with enough water. some have little sensors that wont let it turn on with out enough water. The button may feel spongy because it is using air to turn on the pump switch so give it a good quick push.. also the last things to check will be to check the breaker box and be sure the breaker is on, turn the breaker off and on to test. also look around the room of the tub and look for gfi plugs and switches that may be tripped. they will look like the wall plugs for hair dryers but, may not have outlets on them. just reset all plugs you find in the rooms. Hope this helps you. ask more questions if you need to.

mine did the same thing. the tub is plugged into a ground fault interupter (gfi) plug. hit the reset button. if this doesn't work, check the circuit the gfi is on, sometimes they are on the same circuit as the plugs at the sink. check them for reset also. if this fails, on the motor of the tub, there should be a reset button. try to reset it. OH first make sure the breaker has not been tripped.

i have the same model after unplugging everything one by one i got the breaker to stay on with the transformer unplugged. ordered new transformer installed works great!!

Breaker, even GFI's are designed to trip at 135% to 600% over there load rate, so not to scare you but it depends more on the wire used from the main panel to the dryer/hot tube then the breaker. A GFI's claim to fame is the speed at which it will trip if voltage is detected on the ground side of the breaker. So to answer a question with a question, Can you overload a GFI without tripping it, Yes you can, just be careful the life of your hot tube motor and heater could be in danger if you overload the circuit.
