Yet another Hobart Am15
Unit will display E4 indicating a fill problem. Unit fills, stops and starts booster heater. Starts to fill again and will stop then show E4. Strainer is clear, pressure is at 15psi. Float switch works fine, reads closed or open all the way to the board. New vacuum breaker, I think I wanna change the regulator due to rusting inside, but I can not nail down why it thinks it isn’t filling properly.
Any help would be appreciated.

Even with the water level just below the float the unit will fill for a minute or two and throw the E4 code.

Is there water coming out of the drain? How long does it try to fill and does it reach the water level probe at all?
-
With a Vl, the ML number should be
ML-130153. That means you have to have both a hot water and cold water supply for the condenser. You aren’t getting water back-flow from a wash station having both valves open on the rinse wand are you. The cold has to be below 90F -
I was running into a similar issue with my hobart dishwasher.
I replaced the o-ring that is attached to the drain for the machine and it stopped having issues.

That’s very common on all dish washers. Or food particles that got by the pre-wash / scullery.It’s the first thing one normally looks for with water issues.
