Testing your hot tub’s ability to heat is an important element of any spa. In order to test this element, it’s important to use an ohm meter. An ohmmeter is used to measure electrical resistance and is operated solely on battery power.
When it comes to testing your hot tub’s heating, an ohmmeter is used on its lowest setting to test the leads. This means the meter is testing the measurements between the resistance between two elements. Ultimately, this will tell if your hot tub’s heater is working or not.
What causes a hot tub not to heat?
If your hot tub isn’t heating up, as usual, there are two possible things that are going wrong; the heater element or the flow of your hot tub’s pump. If the heater element isn’t functioning properly, then your hot tub won’t be able to heat up. Or, if your hot tub’s pump isn’t blowing as strong as it’s supposed to, or has a low flow, then this is another cause.
Generally, many hot tub heating failures result from low pH levels in water supplies or corrosion. These are issues that can be easily fixed. However, they need to be spotted as soon as possible.
How do you test a hot tub heater with a multimeter?
A multimeter, also known as an ohm meter, is a resistance measurer that will test your hot tub’s heater. And testing your hot tub with a multimeter is easy. All you need to do is place your ohm meter at 1,000 and test each of your hot tub’s heating terminals.
Because this meter tests for resistance, any measurement from 9-12 is considered great. This means if your hot tub tests well within this mark, things are functioning. If they test under the given values, something may not function properly.
How do I reset the heating element in my hot tub?
On most hot tubs, a reset button can be used in the event of overheating or power surges. Of course, different tubs may vary, but likely there will be a reset button that is located on the side of the control box. This control box is usually found behind your hot tub’s removable panel on the front side.
When this is pressed, you should let it settle for a few minutes before powering on again. This will ensure that your tub has the proper time to settle and reset.
How long does a heating element last in a hot tub?
In most cases and for most tubs, the life span is about five years. This means that after your spa hits the five-year mark, your heater may start to deteriorate. Of course, this will only depend on the usage of your tub, how often it’s cleaned, and other individual factors.
Generally, you will be able to tell if your hot tub has lived past its lifespan and is in need of a replacement. To test your hot tub’s heating element, you can take numbers by using an ohm meter. This way, you can determine if it needs a replacement or needs to be scrapped altogether.
How do you know if your hot tub heater is bad?
To rest if you have a bad hot tub heater, there are a few things you can do. First, you can always test your hot tub’s heating element with a multimeter or ohm meter. This is the easiest way to test if your hot tub’s heating element is working properly.
On the other hand, you can also look at the copper tabs, or wires, on the heater elements pack. This way, you can disconnect the heater and see if the wires are functioning properly or if they are worn out, causing your heating unit to not work.
