I have an Electrolux W4190N commercial washer. It gets through to the first rinse cycle and stops with a no water warning. If you just push the start button it continues on through the program with no other issues.
I don't seem to find that model number. Most Electrolux dish machines start with 2 to 4 letters, like WTCS or RTCS. If you can verify the model it would help. Is this a flight or rack machine?
Sounds like the machine is not seeing water pressure. Verify that the house pressure is above the minimum specified by your owners/install manual. Verify that the pressure regulator is set right and the strainer screen is clean. Also that the rinse nozzles are all in place and the wands are piped tightly. Some machines also trip on low rinse temperature. verify booster temp and incoming water temp. Lastly, it can be a sensor problem. Being electronic it can be as minor as a little connection resistance to a failed or out of spec sensor. Electrolux does not like to share wiring diagrams or service manuals, So information is hard to come by for detailed help.
