Hey @Scott33, I have an Aleko spa with the same kawaii 1805 element and somehow found this forum with your post.
I know the heating element is broken and not one of the sensors because I put my multimeter on it and it's an open/broken connection.
I bought a Camco 1000 watt RV heating element from Amazon, but I agree with the rest, it seems like it will be too long for the housing.
The official element is 4-1/8" long, the enclosure is only 4-1/2" long. So, very curious how you modified it to work.
If I can figure something out in the next few days, I'll share pictures here.
Thanks!
