The spa is not wired correctly or the dip switches on the spa pack are not configured correctly. Use a multimeter to verify that you have 2 x 110 legs feeding your spa pack. If you do there is a dip switch diagram on the back of the spa pack access panel.

SOURCE: No Heat from Spa


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: SPA Filter on while Spa is Heating

you have one jandy valve ( the suction valve in front of the pump) that is not working right when you press spa mode. have someone watch the valves to see if they move when you press spa mode and heat inside the house. if the one in front of the pump does not move and the switch is in operating mode then that valve is bad and will have to be replaced.

SOURCE: pool heater will not turn on, elec. power good,

Check the limit switch. It may be stuck open and if it is it stops the unit from running. Also check thermostat setting and make sure it is working. Make sure the flame sensor is working. The system will start sometimes but if the flame sensor doesn't see a flame it shuts down. Good luck...Lee

SOURCE: My spa will not heat. The heater shows that it's

When you say that the heater shows that it is working is it the heater that shows this or the Aqualink. If it is the aqualink it could be a temp sensor, probally the water sensor that is in a pipe comeing from the pump. But the first thing Iwant to think of is your temp is set on the Aqualink but the temp is not turned up on the heater. If your heater is not compatiable with the link you need to keep the thermostat at max and set to pool or spa to have it work. If it is compatiable it could be in the wireing between the two or you just may need to be sure the Aqualink is set to read and override the heater. Your menu can walk you through this or your book on the unit. Let me know how you do and we can check for further problems in your heater. If so let me know brand and model of same. Good luck.

We can't get our hot tub to heat. The heater light comes on but the heater still won't heat.

heating elements are resistors that get hot
one end will have 115 volts but the other end should be considerable less because the resistance of the heating element drops the voltage
if you used a ohm meter you should be reading a resistance of 500-1000 ohms for a good heater element but with your readings , there will be no resistance so the element is faulty

How long should a 2007 eclipse spa take to heat up??

Usually spas heat approx 5 degrees an hour. If its been a day or so and your water isn't up to heat, you probably need a new heating element in your spa. Check the voltage at your heating element, and on your topside there is usually a heat indicator light that should be lit. If it has correct voltage at heater and the indicator light is lit, heater burned up. If you have incorrect voltage at heater check fuses for a possible blown fuse and see which pump it goes to, that could be your problem.

Water heater can be added to any incoming water line, either on hot or cold.
Under-counter water heater located near tub will supply hot water just like ordinary household water heater. But it will not reheat water that circulates inside the spa tub.
Otherwise, a spa heater is made with electric element that can work with 120V or 240V. Water from tub circulates through tank that holds element. Element must be fully immersed in water.
To retrofit spa tub with this heater would require cutting water line near pump, running both ends of water line into tank with element.
Then of course you would need to retrofit adjustable thermostat to control when element is on. And integrate element operation into air control switch at tub that can override thermostat so element is not heating when tub is not in use.
Unless there is a pre-packaged kit to retrofit heater, I think adding heater would be difficult.

Hi, I have spa form prestige 50 and i cam home from work and it had cut out, I restarted the jacuzzui and it went though the 4 minute prima mode and then cut out again. Please can anyone give me some

it sounds like the heating element is out. Undo the wires going to the heater and then turn the breaker back on. If the heater is bad then it will go through the purge cycle and continue to run but obviously not heat.
If this is the case then you need a new Spa Part heating element.
On the heater tube is the information you will need in order to find a replacement.

Assuming there aren't any other faulty electrical components your GFCI will trip as a result of the heater element short circuiting.
Typically this happens when water infiltrates the heater element's protective outer coating and comes in contact with the internal heating coil. The culprit could be corrosion but usually it is a pin sized hole in the element which will lead to a short circuit.
When this happens the element has failed and cannot be repaired it must be replaced.

I have a 700 litre outside spa pool with a 1 kwt heater.I only turned it on today but the suitable tempiture of 37 celcius (about 100 oF )cannot be obtained.It has been on for 12 hours today.

A 1 Kilowat heater is very small and 1/6th the size that you would use on a 300 gallon spa. Theres a good chance one or more of 3 things are happening.
-Heater is undersized
-Not enough water flow through the heating element
-Calcium or salt build-up on the heating element.

Replace the element, and do ot with a 2-3KW heater at least if your spa pak will allow for it.

Will not heat, it only blow cold air, how do I change the heating element inside the unit

If the drum turns, it could be as simple as a blown fuse or breaker. The dryer has doule breaker or fuses at fuse panel. If the one blows, the heater will not work but motor willturn as motor rums on 110volts. It may be cut out thermostat or could be element, but check the power to the plug of dryer out let and make sure you getting 110 volts on from neutral to both sides and 220 between two live lines.
