What to do if Menards MasterForce MFX2U2000 turns on for 2 seconds, shuts off, and won't turn back on?

When the water is connected, the accessories are assembled properly, and the power is turned on, the Menards pressure washer may turn on for 1 - 2 seconds to prime the pump. It automatically shuts off and waits for the spray gun trigger to be pressed. When the trigger is pressed, water starts flowing through the pump. The water sensor in the pump “senses” the moving water and automatically turns the pressure washer on. You can also try turning the power off, holding in the trigger on the spray gun so that you have a steady stream of water. While you are holding the trigger open on the spray gun, at the same time, turn the power on.
