Now that the "Numberphile" YT channel has revealed the answer to the life, the universe and everything:

I had to check it with my DM42. Well, it cannot calculate it's own self

Yes WP43S can!
But DM42 can calculate 43
12^3 + 8^3 + (-13)^3

You can simplify the example for the testSuite for 43 (2^3 + 2^3 + 3^3), but I think for 41 there is no solution.

WP43* does also work the new non-trivial solution for 3 as well...

It's probably possible to calculate this on the dm42 you'd just have to write an arbitrary precision program, then calculate it.
Assuming the problem is related to precision.

Yes, it is related to precision. WP43S allows for integers with 1000 digits.

Jaymos,
How can we transform a DM42 in a WP43 ?
HP33E, HP34C, HP41C, HP16C, HP28S, HP42S, HP48S, HP12C, HP35S, DM42, DM41L, DM15L, DM41X (SN#15) and HP3000 @ work during 18 yrs as IT Mgr
