I'm guessing the er16 comes right when the print would have ended? So if it was a 40 minute print and it stopped moving at 20 minutes then another 20 minutes later. At the end of the print it does a G28 which homes the Z axis and gets an error because it never hits the limit. I think the 24V is not reaching the steppers. I expect the nozzle and bed also slowly cool down once it stops moving.
If so then you need a new PCB under your printer - the largest board - the white one.
Contact your reseller. They may honor the warranty even if older than 1 year. You could just buy a new PCB or you can fix it - I can help with that if you are good with soldering. I think it's possible that it's with the K1 relay (not 100% sure the UM3 has that circuit but probably it does) which also failed on one of my UM2s (but my UM3 is fine). the fix was pretty easy - required soldering a wire across two points on the board.
Either way something is wrong with either the red circuit board or the white circuit board under your printer and more likely the white one.
er16 came in 1/3--1/2 of the print. (and it wasn't any big -- just two tubes d32x2x18)
If you are right about 24V -- where should I measure it? I have mutlimeter somewhere around. Before I start to break things apart it would be nice to check it.

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
