Hobart dish machine is saying Probe Error - Wash please help

SOURCE: dishmachine won't fill

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.

If your water is hard, the booster and vacuum breaker may be restricted with lime buildup. Remove and clean as required,
