This machine has been acting up for weeks. Got it in shop now. Model WFW9400ST00
Will not turn on with power button, only beeps 3 times, but if let plugged in for a while will start flashing F-70& at times has even flashed F-71. Door will not lock, drum will not turn. Will not go thru diagnostic test. Interface boards have been changed twice & main control once. Have checked & ohmed out wiring & plugs. Running out of ideas. About ready to give it the boot.
Any body else had probs simular to this.
