E1 means open thermistor. Clean lint duct assembly and blower. Make sure you have good air stream from the vent outside. If this doesn’t help, replace the thermistor.

F03 MEAN SENSOR DEFAULTPUMP OR LENT

EC4 The temperature of air vent
Within 30 minutes of dry cycle there is 5 minutes in which the temperature is not increasing.

You need to call for repairs. Probably the heating element is faulty.

You can create a custom program without a dry cycle and hang dry your clothing.

“E2” flashes if the thermistor has shorted.

The thermistor monitors the exhaust temperature
and cycles the high-limit thermostat on
and off to maintain the desired temperature.
1. Turn the dryer off but keep the electrical
supply connected.
2. Make sure that the dryer is empty and that
the lint screen is clean.
3. Close the dryer door.
4. Select Heavy Duty, Timed Dry, More Time
or Less Time, End of Cycle Signal (Louder)
and Start.
5. If error codes E1 or E2 flash on the display
after 1 minute and the dryer turns off,
the thermistor, or the wire harness, is either
shorted or open. Check the wire connections
at the thermistor or the machine
control electronics board. If wiring checks
okay, replace the thermistor.
6. If the dryer seems to operate normally, remove
the exhaust vent and start the dryer.
7. Select the desired temperature cycle to be
tested, and select 20 minutes of Timed Dry
heat using the More Time or Less Time
pushbuttons.

Most customer manuels have a code listing in the back? Have you checked to see what E1 is? It sounds like its not sensing properly. the sensor works off the vent...so the most common problem is the vent or venting. Please check and advise
