Replace the thermistor to restore normal operation. It opens when appliance gets to certain temperature and then closes again to restore heat. That sucker will never work until you get a good thermistor in there.
You can always jump it and get heat but there is no safety valve in case unit overheats - could have a fire. Your call, your life.

The "F25" indicates the INLET THERMISTOR is shorted or the INLET THERMISTOR circuit is shorted. If you replaced the inlet thermistor and control board then it may have bad inlet thermistor circuit. You should disconnect the thermistor circuit connections at the thermistor and control board and test the thermistor circuit for continuity. Check the circuit to see it happens to be open or shorted with an ohm meter.
The inlet thermistor is located on the side of the heating element housing is a thermistor and high limit combination. The part number is 8557403. The inlet thermistor portion of the thermistor/high limit will have two solid red wires connected to it. It could have faulty new thermistor or it could have an open or shorted thermistor circuit or a faulty control board. The thermistor can be checked with and ohm meter. Disconnect the two red wires and place the ohm meter leads across the two terminals. At room temperature it should measure approximately 50k ohms of resistance. If it measures 50 k, then it should be reconnected and then the sensor circuit disconnected from the control board and retested at the harness wires to see if you get the same measurement reading. If it does measure the same, and it continues to display F25, it could have a faulty control board.
What is your model number?

Hi Nora King - Error code E70, typically means that there is a communication error with the outlet/inlet control thermistor that has an open or short circuit. You will need a certified professional to check the resistance of outlet/inlet control thermistor and check wiring for either short or open circuit.
