Question about Hayward 11kw Electric Spa Hot Tub Heater Cspaxi11 ()

Open Question

I have a 11 kw hayward heater. I replaced the 50 amp breaker, contactor, and both heating elements. Breaker keeps tripping on the unit. There was a lightening strike which fried the items I replaced. Any ideas why it keeps tripping? Thanks. Todd

Chances are that your element is drawing too much current. Check the manufacturer's website to make sure that you have the correct size breaker installed. Low water flow could also affect this, so make sure all of your baskets and filters are clean and clear.

You are probally having a problem with your pressure switch in the heater. This is located in the cabnet on the left side about half wau up just above the burner tray. It will have a ferrel nut on the back you can unscrew to get it off the copper tube it is attached to. Do this with the breaker off and once it is removed from the tube start the pump for a second and see if you have a freeflo of water from tube. If you do you need to ck the pre sw by replaceing the unit on the tube and removing one of the wires to it. If this solves the problem you probally need to replace the switch. If you don't get water flo through the tube you will need to follow the tube to where it hooks to the manifold and remove it there and clear the hole it goes into and the tube it self. This is a rare occurence on these heaters as they have plastic headers. My bet is you will find the pressure switch has gone bad. Good lucl I hope this has helped.

SOURCE: Hello, please tell me what breaker (amps) do I

Hi and welcoe to FixYa, I am Kelly.
11,000W is the maximum power that it could draw. Given the wattage is over 10,000 I am certain that your Spa / Tub heater is 220 VAC If it is 220 VAC then you will need a 50 Amp breaker. If it only 110 VAC you will need a 100 Amp Breaker. (Gasp!)

Amp consumption will always vary.
Heater on / Off
Number of Blowers and pumps in operation at any given time. Then add lights to the equation. My best guess at any given time it is in "full operation" it will average 6,000 - 7,500 watts. When not in full use it the average amp usage would drop substantially.

Thanks for choosing FixYa,
Kelly

Why wont hot tub heat with jets on losing temperature on 110 volt


My first question would be about the outside temperature. What is the outside temperature?
Hot tubs that are designed to operate on 115v only have 1.5kw heaters and if the outside temperature is below 50 deg F they tend to not keep up to 103 deg water while being used. They are also designed to not heat while the high speed pump is operating.
Does it stay up to temperature on a normal basis?

Hatco booster blowing breakers


Copy following link:
http://waterheatertimer.org/Water-heater-is-blowing-breaker.html

Hatco booster heater typically has 2 sets of thermostats and elements located on each end of heater.
Both sides might be controlled by same 60 amp breaker, or the heater might be controlled by two separate 30 amp breakers.
Be sure you have correct wire and breaker.

After reading steps on link above, add comment and say if this is new installation, or older installation that suddenly started throwing breaker.

Breaker tripping


This could be a heating element issue. it could be a bad element. Disconnect the two leads going to the heating element and then turn the breaker back on. If it will run and not trip the breaker then you have found the problem.
On the heater tube there is a silver sticker that will have the information you need to identify what model heater you have and what the kw of the element is. It will either be 4 Kw or 5.5 Kw
You may contact us for more information about this or purchase the replacement element at www.uspartscenter.com

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.

Rheem 50 gallon Electric Water Heater 81V52D C repair ideas needed


It could be element shorted to ground through steel tank, so don't touch tank when breaker is ON.
Or you have undersized 12 gauge wire and 20 amp breaker and the heat has loosened breaker on the busbar. Breaker trips when heat exceeds breaker limit. Jiggle breaker and listen for crackling sound.

To restore hot water now:
Turn off circuit breaker, and open top cover then Push in reset button on top of heater to restore functionality. Put back insulation and factory cover.
To fix water heater: test and replace bad element.

Hello, my heat pump is a 4 ton unit, it heats ok but it keeps tripping one of the breakers, the 40 amp cooling breaker. I have put a new thermostate, it keeps running after the breaker is tripped and the...


Hello Jack,

Let me see if I have this right. Your heat pump keeps triping the breaker that is going to your airhandler. The Heatpump is on its on breaker and can not trip the breaker on your air-handler. However, the 40 amp breaker is to you heat pump its self (the outside unit). The thermstat is not the porblem as all it does is call for heat or cool. The problem can be one or a cobination of three things the contactor, the run capcitor or the breaker is weak.

The first thing I would do is replace the breaker as if it has tripped more than twice it needs to be replaced. Then I would look at the contactor, it is located underneath the service panel it will have some low voltage wires on the sides and a black and white wire running to it from the disconect box. If you notice the contacts are chared (little copper points in the middle of the contactor) I would replace it. If the contactor looks good I would remove the capcitor (carefully not to touch to contacts at once as they hold a charge) and take if to the local parts house and have it tested.

I hope that I have asnwered you question and you are able to take care of the problem. Thank you for using FIxya and do not hesitate to ask more questions.

What size breaker does the 11kw hayward comfort zone electric spa heater require?


It does make a difference as to input voltage. But usually at 11KW this would be a 220V unit and require a 50 amp breaker. 11,000W divided by 220VAC = 50 amps. 230 or 240V input the same 50 A breaker.

Thanks for choosing FixYa.

You should check your water flo, clean your baskets and filter. Not enough water flo will let the element overheat and can trip the breaker. This could be why you had to replace the element already. Good luck.
