Hi, welcome to Just Answer. My name is ***** ***** I look forward to helping you! If the valve is new, the flow meter in the inlet assembly is likely faulty.

Should the water enter the dishwasher from the condensation vent on the side? When we started to run it with the door open, that is where the water was filling the bottom of the dishwasher at.

It enters at the left side, through that part I sent you the link to.

Kelly, I installed the new part as you recommended. and I am still getting a water supply error. my previous dishwasher did not have this issue.
Expert:  Kelly replied 8 months ago.

Is water entering the machine even though the error appears?

Customer: replied 8 months ago.
It Trickles in through the vent of the part I just replaced.
Expert:  Kelly replied 8 months ago.

So when it errors out, is it full of water or very low?

Customer: replied 8 months ago.
very low. it only runs for about a minute before it error and drains.
Expert:  Kelly replied 8 months ago.

Is there good water pressure to the valve from the home's supply?

Customer: replied 8 months ago.
the plumber came out and checked the drain and water supply. bc we recently had otherwork done to our sink. I wanted to double check first I started ordering parts.
Expert:  Kelly replied 8 months ago.

Well, if you have good pressure to the valve, the valve is new and the inlet is new, I am not sure what is going on. I suspect the water pressure to the valve may be too low.
