Re: Intermittent HFS-3 Failure
New information: After showing the above symptoms for a couple of days, now whatever is failing has dropped functionality further ... no more self test or flow light, the only thing that happens when I start the truck is the water level light comes on for 5 seconds or so and nothing else ... no other lights at all. I've checked all the wiring ... unplugged and re-plugged the switch/FAV etc. and nothing changed. I'm not driving it today so I have to wait until after work to troubleshoot further ... unusual how the system worked perfectly after install and has gradually come to this ...
