have a Hoover OPtima washing machine WMH 147 DF. It is filling up with water and not stopping, also the panel lights and wash cycle time display are not coming on. It's only 1 old

The clue is in the water temp. light flashing. DF means that the temperature sensor is faulty. Replace it with a new one. Turn power off at wall. Remove the 3 screws & open panel. Sensor is plugged onto control board near the middle top of board & goes down into the base of the control panel at the middle where the water enters the machine. Unplug from the board taking care not to damage the pins on the board. Replace the new one making sure the o-ring is on it. Close up panel & turn power back on.

Hello Shirley - Typically error code ER01 indicates that a water leak is detected under the tub. Unit will possibly need a hydraulic kit. Try unplugging the unit or flipping the household circuit breaker off. Wait approximately ten minutes and turn the unit back on. Could the error code DF possibly be PF? If so, PF means power failure and you should be able to start a cycle. If the error code continues to display on dishwasher then I suggest contacting a professional to accurately diagnose and repair it.

error code E401...DF paper feed motor lock...check the motor of your DF...try to turn off the machine and unplug the communication cable from DF to the machine and turn on the machine again...

DF means the temperature sensor is faulty. Replace it. Get a new one from your Simpson agent. Turn power off. Open panel by removing the 3 screws at the rear of panel & swing it up. If you are standing behind the machine look on the left hand side at the top of the circuit board. You will see a small white plug with 3 wires (red-white-black) Very carefully pull this plug toward you off the 3 pin base. The other end is the sensor pushed into the water inlet chamber. Pull it out. Push new sensor into water chamber (make sure black rubber o-ring is on it) Push wiring plug back onto 3 pin base. It can only go on one way. Do not force it or twist it as the 3 pins can be easily broken or damaged. Then close panel & power up.

Does your machine have a ADF ( document feeder) on it? IF it does check the connection between the ADF and the machine. Also check the connection between the scanner PWB and the DF drive PWB. These are the 2 boards that let the machine communicate with the ADF. If your machine does not have an ADF, check to make sure that the side covers are closed securely.
