Exhaust thermistor failure
Unplug the dryer and check the exhaust thermistor wiring. Reconnect any loose wires or replace the wire harness if damaged. Check the resistance of the exhaust thermistor using a multimeter. You should measure about 10,000 ohms at room temperature. If not then replace the thermistor because it's defective. Replace the main control board if the exhaust thermistor and wiring are okay.
Door switch error
Check the operation of the door switch using the diagnostic test mode, which is explained in the tech sheet that's typically stored in the console of the dryer. Replace the door switch if it doesn't work.
Power supply error
The power cord on the back of the electric dryer isn't correctly connected. Unplug the dryer and connect the power cord according to the installation instructions.
Steam generator thermistor failure
Unplug the dryer and check the wire harness connections between the steam generator and the main control board. Reconnect any loose wires or replace the wire harness if damaged. If the wire connections are okay, replace the steam generator because it houses the steam generator thermistor. The steam generator thermistor isn't sold as a separate component.
Steam feeder is dry
Refill the steam feeder with water.
