No h2o fill

This important part is right at the end, you have a well!! It sounds like you may have run it dry? Check the well and the pump first. The rest is stop valves and pipes to the tank and beyond and not likely to be causing issues. Your sediment issues and problems with the anode is also due to using well water which is nearly always loaded with minerals..

h2o is the chemical symbol for water. But if the water keeps running and does not stop, even when the machine is full it could be the machine has a defect level indicator, or the water lock does not work. When the lock even don't closes what you remove the power the lock is defect.

My 99 DeVille almost impossibe to access radiator drain so I just remove lower hose to drain it.

sounds like you are having a syphoning issue. caused by having the drain hose too far down the home standpipe. very common problem. test..fill the machine, high water level. when it stops filling turn off. advance into spin/drain for just a moment and shut off. listen to hear water still going down the drain.
repair.. raise the drain hose nearer the top of the stand pipe. also do not tape/seal the hose into standpipe. it has to breath. good luck. kihm washing machine drain hose installation Google Search

What you hear is the drain pump, remove back panel to see the problem

replace any soft hoses.
collapsed hoses cause water flow constriction
.that increases temp fast

to bleed air out of the system . if no air bleeder as such
with heater on full .-engine running
loosen the bypass pipe for the closed thermostat till only coolant flows no air bubbles
check if
the engine cooling fan spinning fast enough
the water pump in good condition
the interior directional flaps motors or actuators working

i`m guessing the blower motor is working.check coolant level then run car until hot,that is the upper rad hose is hot to the touch.then touch the heater hoses they should feel the same in temp from one to the other.if not then the heater core is plugged and will have to be flushed.you can clamp the hoses with something so you won`t loose very much coolant.then remove the hoses and using a garden hose run water one way then the other way.if this doesn`t work you can try and drain the heater core and fill it with clr and let it sit for a while(about 30 to 45 minutes)then flush the heater out with water.then hook up the heater hoses and run until hot,if it works then you will have heat and unplugged the heater.if both hoses are the same temp then replace the thermostat.

H2O is the symbol for WATER and probably indicates a WATER related fault on your machine. A pressure switch is the normal way the machines 'sense' when the level is sufficient. Overfilling suggests a faulty switch, which will need to be replaced by a technician. Also, ensure that the machine drains as it should, if not, the pump filter may be blocked.
