you need to have your air conditioner serviced.
If it displays E2, E3, or any other E error, you also need to have your air conditioner serviced.

The E1 Error Code
The most common reason for an E1 error code to be displayed on your air conditioner's front panel is to remind you that the unit's air filter needs to be cleaned. Many models will automatically notify you of this via an E1 error code display after the unit has been operated for a predetermined number of hours. For example, many Sharp models will display an E1 code after 720 hours of use. Alternatively, you could have dirt or moisture in your front button controls, causing them to stick or not function properly. This can be a common problem with many models of Haier air conditioners, but the issue is not restricted to any one manufacturer. Your air conditioner could also have a defective thermistor, which is part of the thermostat.
For Samsung, the room thermistor needs replacing. This is a device that senses the temperature in the room.

Press the "Power" button to turn off your unit and then remove the filter from the filter panel on the side or front of your air conditioner. Refer to your manual if you are unsure where the filter on your unit is located.
Inspect the filter. If it is dirty, brush off dirt, debris and lint. If it is really dirty, wash it with mild soap and water and allow it to dry completely. Reinsert it into its compartment. If your filter is worn out or damaged, purchase a replacement filter from an appliance or hardware store and replace the old one.Turn on the air conditioner. Move to the next step if the LCD continues to display the E1 error code.
Check for a reset button on your air conditioner and press it to reset your unit. Some of the newer air conditioners have reset buttons to restore the default factory settings. Press the "Power" button on the front panel of your air conditioner to power down your unit if it does not have a reset button. Unplug the unit from the electrical outlet. Leave the air conditioner off for several hours to see if it will reset.
Plug your air conditioner back into the electrical outlet and turn it on. If your air conditioner is still displaying the E1 error code, turn it off and contact a qualified technician because the room thermistor responsible for detecting room temperature may be defective.
The E1 code is an error code that appears on the LED temperature display of some digital air conditioners. The error code could mean anything from dirty air filters to a damaged room thermistor, a safety connected to your thermostat that detects room temperature. Troubleshooting the cause of this error code may improve your air conditioner's performance
Unfortunately, there's not much you can do. The E1 error code indicates a sensor shutdown. However, you can try turning the unit OFF & unplug it for 15 minute. Then plug it back in and turn it ON. If the electronics reset and reverted back to the original factory setting, you can set the controls as you like.
If you continue to get the E1 error code,, contact Haier Customer Support 1-877-337-3639.
