How did you clean the head? Did you by any chance use a wire brush while the heater was on?
Endstops not working (either always triggered, bed or head won’t move, or not triggering when at endstop), and/or seeing the probing sequence just immediately move to each of the four washers without probing downward to touch them – typically means a shorted wire or a blown mini-Rambo board. The usual cause of a blown board is shorting the heater wires to the heater block, either due to broken insulation on the wires or using a wire brush which penetrates the insulation and shorts it to the heater block. That runs high current meant for the heater into the low current circuit used for endstops, and can permanently damage the board.
Power off/on the printer, then use Cura controls to move the bed (Y) and toolhead (X and Z) a short distance away from their endstops. Then open a console and send an M119 command. The printer will respond with endstop status; they should all say “open” if you have moved everything away from the endstops. If one or more says “triggered” when not actually at the endstops, then you either have a shorted wire or a blown mini-Rambo (the odds of it being a blown mini-Rambo go up if more than one shows triggered).
