Frigidaire washer When I press the start button, the door locks and nothing else happens. Similarly, the water was not switched on. I can't turn on the water valves since I don't have any power. I double-checked all of the connections and found them to be in fine working order. I believe I've boiled it down to either the control panel failing to provide the start signal to the main board or the main board failing .
Disconnect the J9 connector from the main control board and inspect the harness for the same circuits/wires. Repair the main control board if the readings are right. Here is a link https://www.upfix.com/product-category/appliances/washing-machine/
