Question about Hobart 24 in. LXIH-3 Built-in Dishwasher
It seem that the machine isn't filling enough to hit the probes required. It might be that it's draining at the same time or something...
Error Code E3 relates to a problem with the fill. Specifically that the water level has not been recognized at the middle water sensor. This can be caused by a problem with the drain system as you describe, or by low water pressure to the machine (should be 15-25psi flow), or bad wire connection to this middle sensor.
Check for proper water pressure first (should be a gauge on the machine) during the fill. Then check / repair drain as needed. These will probably eliminate the problem

Your problem is as straightforward as your observation, the unit is not getting enough water flow.
First, if your DW water is hooked up with a braided stainless hose, there is usually a screen in the end of it, (check both ends). It gets clogged with debris and chokes off the water. Make sure the line is not kinked.
If that doesn't work, you are likely having trouble with your fill valve. It is under the front kick panel. It has a large castle like upper cap. It is common for debris in the water to make this valve malfunction. It isn't too difficult to open up without removing. Just watch how it is assembled. If you pay attention, it's easy. If you have a booster, the hoses are very brittle with age.
And otherwise, the fill valve may be bad. REMEMBER, verify your supply water flow where it connects to the machine first. Don't assume. You could have a pressure regulator or a line strainer that is part of your supply line. They do fail. But that's a plumber's fix, not a technician.
