The condition you see on the topside control is known as "watchdog" Which usually means that the spa thinks it's "overheating"
Turn off the power to the spa for a couple of minutes, then restart, Watch the topside control if the temp. starts to climb & read a lot hotter than the actual water temp. Then it goes into watchdog, most likely you have a bad temp sensor. In some cases just resetting the spa will clear the watchdog & everything works fine. (Voltage fluctuations, "spikes" can freak out the electronics & the tub goes into watchdog to protect itself) If the spa immediately goes into watchdog when you reset it, you might have a bad board. (Let's pray it's not) 90% of the time it's a bad temp. sensor.

I have a J340 Spa that is throwing the watch dog mode --- error code. I have replaced the temp sensor and the circuit board. Can a malfunctioning circulation pump cause this problem. Thanks.


yes, it can as can the hi-limit as well.

Is the watchdog, consistent or does it show up every now and then?

If not consistent: then it is an indication that there is a "Potential" problem, not necessarily always indicating a problem is there. Power fluctuation will cause this as well.

You may need to monitor for a while.

I have a Jacuzzi J340 Hot Tub. I am having trouble with the heating. When the pump is on, the water circulates just fine. once the heater kicks on, it runs for about 10 seconds, then clicks to OH, and...


make sure the heating element isnt touching the casing inside the heating tube. if its an indoor tub, make sure the filtration cycles are not set to constant. constant filter cycles on an indoor tub will generate residual heat from the circ pump running 24/7, causing tub to heat past 104 degrees

Jacuzzi hot tub, Water is too hot. Heats until it trips the system. I have replaced the analog temperature control,


1) Safety question first
Why hasn't the GFCI tripped.
If your spa is not protected by ground fault., then you are at serious personal risk.

2) Replace the element.

3) If element is cracked, it can continue heating to ground wire, causing runaway heating.
This applies to spas, and water heaters of all type.

I have a Jacuzzi Z 145 spa. I was constantly getting an FL error. Purchased a new switch, put it on and when I turn the spa on I immediately get a circuit blow. What could be causing this problem?


Its possible your heater has a ground fault. If the old pressure sw was giving the FL code the system would not send power to the heater. Now with the new sw working power is being sent to the heater.

Jacuzzi Laser II: Problem with the Heater/filter setting. The jets come on when it's on this setting. When I turn it to Filter setting it's fine..when I turn it off the jets come back on What gives?


The jets will run while in the filtration / heating mode. If the spa is in the middle of the filtration cycle, the jets will stay on until the cycle time runs out. So, if the spa jets are on during this time, they are on for the full duration, 2-6 hours every 12. You can cycle the jet button to high, but when you try to turn them off, they will just go back on low.
