Question about Pool & Spa Heaters

No Heat from Spa

Bret Aquiline spa: Replaced Heater Element, New Pressure switch,
Two Heater contactors (buzzing), Heater Relay, and GFCI switch..
Everything runs as it should hi/low. Indicator switch on console lights
up ( +clicks) when calling for heat. There is No Heat, and the Heater
Light ( replaced new neon light; directly connects to the heater element), does not light. (Didn't check voltage at heater, but suspect its not getting power ?
Everything seems to run great, but no Heat. Can I jump the two wires together, that go directly into the pressure swith ( and bypass that switch) to see if I get heat: and can I do the same with the 2 wires going to the hi heat limit switch to bypass that to see if I get heat. HELP !

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.

Reflections Spa will not heat


Take a Multimeter and measure the voltage at the heater element. If it is getting voltage either 120v or 240v depending on the voltage to the spa, you've got a bad heating element

Can I change out a Hayward H400ID with an electric heater for the spa only? If so what electric heater product brand would you recommned. Raypak?


Hayward has manuals for each type heater, gas and electric.
http://www.hayward-pool.com/prd/In-Ground-Pool-Manuals_10201_10551_14502_-1___I.htm
Hayward also has contact page, and can probably recommend correct change-over product.

You want to switch from propane to heat-pump type.

There are likely 3 areas of difference. Read each manual and generally look for 1) unit size and capability to match spa 2) pipe connections and sizes 3) Electrical requirement

From electrical standpoint, You need GFCI-protected line from circuit breaker box, or GFCI (arc-fault) breaker. This will prevent electrocution risk around spa.
http://waterheatertimer.org/How-to-wire-GFCI.html

Wire sizes are based on volts and watt-rating of heater.
Each electrical device has rating plate showing volts and watts.
3500 watts divided by 240 volts = 14.5 amps so install double-pole 20 amp breaker and use 12 gauge wire.
1500 watts divided by 120 volts = 12.5 amps so install sinle-pole 20 amp breaker and 12 gauge wire.

Hello,
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 received my brand new ez spa today and once I got the water in and pushed test on the gfci the spa came on and so did the jets. I understand that the motor needs to run to heat the water but does the...


Yes, the jets will run anytime the heater is operational. This is neccessary to keep the plumbing from melting, and also to evenly distribute the heated water. Most hot tubs only take 4-5 hours to heat up, but the easy spa takes very long because they use a very small heating element. Usually only 1.5KW.

I changed the contactor and the thermostat, the contactor does not kick in right away, is it supposed to? is there something else i need to change? thanks


The Cspaxi series also have a pressure sensor which senses the pressure inside the heating tank. This sensor connects to the coil on the contactor, insufficiant pressure in the tank will cause a delay in the contactor activating. It sounds like your problem can be caused by insufficiant water flow from the pump, a clogged or pinched water line to the heater, or a faulty pressure sensor.

Spa Heater


You need to check your temp sensor and your high limit. Both are tubes that slide into the plumbing on or near your heater. If this is a tube heater then they are probally at on each end of the heater and will have small wires coming from them that go back to the control board. Farely common problem and easy enough to fix with replaceing them both. A number of models wire them together so they come as one part. Good luck.
