About a year and the half ago. Jonas. ABC guy. Chemist put an additive into his stuff so it doesn’t go bad so quickly. He said he used one that was years and years old. It was fine.
I did have a Neptune one go bad. It grew some slime stuff on the bottom of the bottle.
Changing them out after a year is a marketing ploy. Take the heater out. Look thru the glass. If there is no water intrusion. The heater is fine. What goes bad is there’s a rubber gasket at the top. It usually fails from the saltwater and the saltwater Will corrode the internals. This causing a...
All heaters fail. We actually use them wrong. Well at least I do. We submerge them into the water. Which is wrong. There is actually a water line ( glass heaters). You are only supposed to put the glass part into the water the head controller is supposed to stay dry.

No you want to have it on ac. To test it. Put the red wire probe in the right top( small blade ) then put the black probe in the bottom D shaped. Your volt meter should read 120v. Now if it does. Then your one the right setting. Put both probes in the water and see if you get a reading. If you...
I think it’s set wrong. I see ac. I also see hz. USA is 60hz. 120v. Is standard. If your reading 56v with red to power and black to ground. Nothing in your house world work.
Test the water with a volt meter. It will give you a better idea of what is going on. Ground probes are ok. But not a solution. Unplug one module at a time. When the volts drop close to zero. That’s the bad unit. But like Tu said. 99% of the time it’s the heater. But back in the day. I had a...
