Bad heating element. Shut the power to the breaker off, disconnect the wires off of the heating element and then check for (ohms) continuity across the two element leads. If it show OL on the meter then you here is an open in the element and it will need to be replaced. Good luck.

Tcarrigan,

Heater contactors "buzzing": Do you mean normal buzzing or extra loud buzzing? Loud buzzing or chattering can be caused by low voltage to a contactor. If normal sounds, then probably the relays on the contactors is working, but the contacts may be stuck, or burned enough so as not to make contact. First, get a voltmeter and check for 240 volts AC at the heater contactor terminals. If the voltage is low, most likely you need to check the contactors further. Check for dirty contacts, clean if needed. If the contacts are not moving when energized, then you will probably need to replace one or both of the contactors.

SOURCE: My Raypak versa gas heater for my hot tub will not

Water flo through the heater is too fast and the water can't get hot enough. Your by-pass valve is stuck closed and you need to open your water header and check it out. Or you may have an external by pass that need's to be opened 10-20%. This will be a valve between the inlet and outlet water pipes going to the heater. Good luck and HAPPY NEW YEAR.

The users manual for these pool heaters has a very detailed flow chart that troubleshoots these problems. This is going to be your best bet. The link below is a a pdf version of the manual. It should help.

I have a 340 jacuzzie hot tub the temp says 109 but the water is cold ?? whats up


if you do not get a light showing on the topside panel indicating it is heating the first thing to check is the filters. Remove them even if they are new. If the problem persists then check to make sure both valves are completely open on either side of the pump so you have not restricted the waterflow.If the valves are open and the filters are removed and the heat indicator light still does NOT come on then you most likely have a bad pressure switch and should be changed.there are a couple of other things that would cause a hot tub NOT to heat but that is the starting place for you.

Hydroquip heater will not come on & heater indicator light is also out


I would start by checking/replacing the Hi Limit.
When that switch goes bad, it usually shuts down any spa or heater.

The hot tub is no longer heating


There are two main items to check. I do not recommend them unless you are qualified to work with electrical. The 2 main things that this could be are:
1. Pressure switch failure( (hot tubs need a sensor to tell the computer when it is safe to operate. If the pressure switch is out, then it will not heat) if this is a hot tub with a 24 hour circulation pump, then the pressure switch would actually be a flow switch.
Fix: Replace pressure switch/ flow switch
2. Heater element failure. (This type of failure typically trips a GFCI breaker)
if the heater element is out, then it will short to ground causing the hot tub to shut down repeatedly.

Notes: Are there any trouble codes coming up on the display panel? these help out greatly when troubleshooting like this via- messages

I have a 2004 great lakes hot tub with a balboa controler. My hot tub heats up fine when the pump runs on high but the temp light never comes on when the pump runs in low.


check to see that the flow switch is working properly, it may not have enough flow on low speed to allow the heater to turn on. Make sure your filter/s is/are clean. If you have a pressure switch instead of a flow switch, it may need to be adjusted or replaced.

My new heater does not work on my hot tub. I have a Jacuzzi Z135 Model s2600000 with a Controller version r574 and a Balboa 58028 that has been replaced by the 53349 heater (4 KW, 1 PSI set Pressure...


Test across both terminals at the same time. If you are getting 230V, disconnect power and check the resistance across the terminals. For 4kW, you should get roughly 13 ohms. If not, the element is bad.
If you get 0 Volts across the terminals, the tub is not heating. ManyBalboa packs switch both leads to the same leg of power, so you can get 120V to ground from each terminal, but you get 0V from terminal to terminal.
The clincher here is that the "heater on" light is off. I would double-check the pressure switch. You should test it with the tub running in heat mode. Disconnect one of the flag terminal leads from the switch, THEN test for continuity across the terminals. If you get none, you have either low flow or a bad pressure switch. You can verify by jumping the two wires together and see if the "heat" light comes on. Again, check for flow. I would run any of these tests with the filter removed. The symptoms you describe are very commonly caused by a dirty filter causing low flow. Again, pressure switch test. A bad sensor would cause the "current temp" to read too high, and a hi-limit problem would cause the little "heater-on" light to flash. Unless that little light is just dead (I've never seen it go bad), everything you say points to the pressure switch (or a dirty filter).

Jaccuzi hot tub will not heat?


sounds like it maybe the heater again. Have you pulled it out and checked the ohms? it should be at least 10.5 ohms
it could be the thermostat or the pressure switch - if either of those are not working it will not heat either.
