Replacement parts for General Electric EDW6000L00BB Dishwasher | AppliancePartsPros.com

Sounds like a fill problem but have you checked the water level.
Just open the door after when it should have filled.
It should fill to just under the heating element.

Remove the kick plate and check that the overfill switch (Item 308 in Section 1) is activated by the float. If not remove the float cover (Item 302 in Section 1) inside the tub and check it.

If the switch is activated then you will have to check if the fill valve is getting 120 volts when the unit should be filling.

If it is getting voltage then either the valve is toast or it's input filter is clogged. Stuff may have come off the inside of your water supply pipes when you did the other repair.

There is a screen filter on the input side of the fill valve. Remove the valve from the unit and clean/check the filter.
Do not permanently remove it from the valve as it is there to keep crud out of the valve which could hold it open and cause a flood.

If it still does not fill correctly I would replace the fill valve.

PS: Be sure to shut off the power and the water supply to the unit. Have paper towels etc. handy to wipe up any spilled water. Get a small pan/bowl etc. that will fit under the valve then loosen the input water line let it drip into the container emptying it as necessary. This will minimize the amount of water spilled.

If there is no voltage across the valve check for voltage across the fill valve/overfill switch combo. They are wired is series. If you have voltage there, then check across just the overfill switch. If there is voltage across the switch then replace it as it's contacts are not closing.
