Infiniti hot tub reads HL

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

read the pump motor tag. it should have wattage consumption. if u have already been running it, ensure breaker is pushed all the way in. and u don't have a new appliance running on the same breaker.make sure the grounds are clean and tight.thats all I can think of. if persists,use a multi meter and start testing.

change your circuit break amps to higher

Water heater can be added to any incoming water line, either on hot or cold.
http://waterheatertimer.org/How-to-install-under-counter-water-heater.html
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.

when a hot tub flashes a code I have found that 99% of the time it is the the flow switch with tells the mother board that it is ok to turn on the heaters. you need to power tester and check to flow of power to each section on the system. It would help very much if you had a wireing diagrham.

If yo understand power and how it will work a system from the point it ties into the first wire. Take your tester and slowly follow the pathway.

I wish I could paint a better picture where its " just push a button" but I can not.

Best of luck, BE SAFE and dont forget to rate how we helped or hurt you :)

Hi,
In most cases problems with the circulator pump boil down to two problems.
The most common is air in the lines causing an air lock.
The next problem is that the pump gets stuck and is not running even though itmay be hot and seem to be running. In this cause the pump can sometimes betaken apart, cleaned and it will work, but usually it needs to be replaced.

Here is a tip that I wrote that will explain circulator pump problems in moredetail.

Heating Circulating Water Pump Problems

Remove the molex plug from the board, and ohm out the leads. You should get a reading, which then you can check to the manual. Hope this helps
P.S. If you get OL or infinity, then the ignitor is bad, as well as if it reads continuity.

The vent pipe should be in front of the pump so that the pump pushes towards the vent pipe NOT sucks from it. I hope this vent pipe is part of the heating system and not of the hot water
Pumps like to push not pull and therefore it is better if the pump is located further down - say at the bottom of the cylinder or lower.
With an indirect cylinder, the hot water & heating are separate circuits and are not and must not be interconnected. You will need a separate pump for the hot water which should be taken from the hot pipe coming out of the cylinder. You may get vacuation in the cylinder - then you will need an Essex or similar valve to replace the hot water outlet connection
By the way - The pressure at any hot tap is directly related to the height difference between the tap and the header tank in the loft [thus a shower downstairs feels stronger than one upstairs]

sounds like the heating element is going bad, have someone come out and change it, it will be fine

you probibly ran the hot water tank out of hot water shut off the hot water comming out of your fausets for a few hours and check it again u could also try to reset your tank by pulling off the front cover and hitting the reset button and my last thought is sadly you burnt out your heating elements and they need to be replaced good luck man
