My frigidaire 3000 speedclean series Dishwasher's control panel lights started flashing Er and everything was out of control.I tried unplugging and maybe reseting the control panel,that didn't work.I tried replaceing the control board ,but after three days of normal operation it's happening again. the same problems,flashing Er ,does't finish cycles, and starts up on it's own . Could this be a bad control board or should I replace front control panel (flashing light's)also as this could be part of the problem:confused: :(
