All Thermistors now read 2000C

[Zesty_Lykle]

My Delta was printing fine.
This morning I switched it on again after a few days of no activity.
Now all thermistors read 2000C. All three of them. The bed, the hot end and a testing thermistor for sensing water temp.

What could be the cause?
I checked the wiring, all are still connected. Besides, it is all three at the same time.
