Connecting an external 250 mA fuse between E1 thermistor VSSA pin and E0 stop GND pin as a substitute for F1 fuse solved my problem Temperature readings now ok. Thanks again, AndreS and dc42!

RE: Thermistor problem…
Andre and dc42: Thanks for the comments - I'll try the right specs on the fuse… Anyway, processor still working - the X,Y,Z motors are still rolling smoothly (much better than on my old RAMP), and no problems with the web interface

RE: Thermistor problem…
@T3P3Tony: Yes, configured the thermistors as you proposed (one as original E3D thermistor, the other as generic).
@elmoret: The VSSA fuse was indeed popped.
I looked at this thread: https://www.duet3d.com/forum/thread.php?id=222#p2195
Then, as @AndreS had done, I replaced the SMT fuse by putting an 5x20 fuse holder with one connector at the E0 endstop GND pin and the other at thermistor E1 VSSA pin. Alas, still the same issue (and I tried two other thermistors that did work on my RAMPS board). The new fuse (12V, 2A by the way) didn't pop.
The temperature readings still change between "error" and about -14 to -19 degrees Celsius each intervall lasting a few seconds . Other ideas? -
Thermistor problem…
Just got my DuetWifi and now trying to make it work with my Kossel XL.
Installed a brand new 12V E3D extruder and thermistor.
Both bed and extruder thermistor change between negative values around -20 degrees and "error" with a few seconds in between.
That's with standard settings for "chinese type" bed thermistor and original E3D thermistor.
Any ideas what the problem might be? Thanks in advance.
