F77 is the Ceramic Control valve - the fault usually means the control valve either can not switch positions or can not find the position requested - Not to difficult but probably better off to have a service tech to replace it
How do you fix it if you can’t find a technician that can come out soon?

This refers to the water heater no longer heating. There is no user solution, you'll need to call for service.

I just switched machine off for a few hours and when started, it was OK

Hello Wiesiek1,
The water system fault means that there is too much water on the bottom drip pan and it has tripped the sensor at the bottom of the machine. Usually removing the bottom grate where the cups sit and taking some paper towels and soaking up the water/spillage will fix this problem

YOu must turn the machine off...hold both the small coffee and hot water button...tunr the machine on to light...let go of the buttons..then hold in the large coffee button for a few secinds andletgo ..if that doesn't work hold in the medium coffee button for a few seconds and letgo..that shouldreset the brew unit.
good luck
