The '2' in E2 seems to refer to list of conditions under 'Troubleshooting' in the user manual for this product. The version of the manual that I have found claims that in this condition the problem is: "The amount of heated air exiting the front of the portable heater is reduced."
The solution is to: "Check the electrostatic filter to make sure it is free of dust and dirt. Also check the front grill and rear air intake to make sure it is not being blocked by any kind of debris."by BillBell

It has a wiring diagram on the aluminum case you pull out from the wooden box

Hello, no the humidifier does not have a power cord. It needs to be wired to a transformer to provide 24 volts to power it.

this happens when you have run a heater for a long time on an outlet that is either not giving the heater enough amperage or to much amperage try it in a different room if the problem persists try a different heater.

Check for voltaged at the solenoid valve. This will either be a 24 volt or 110 volt solenoid valve. Confirm power into the unit 110 volts. If you have power into the unit and no voltaged at the solenoid valve on a call for humidification at the humidistat than the circuit board or the step down transfgormer has failed.. If you do have voltage at the solenid valve than the valve has failed.

what are you trying to replace it on

When a humidifier doesn't run, it generally means it isn't receiving electrical power or the controls have automatically shut it off. 1) Be sure it's plugged in to an outlet that works and that it's turned on. Check the electrical receptacle for power, using a working lamp, appliance, or voltage tester. 2) If the receptacle seems to be dead, check the circuit breaker or fuse that serves the humidifier's circuit. 3) Check the setting on the humidistat. If it's set lower than the room's relative humidity, the humidifier won't go on; in fact, it may take several hours for the humdistat to respond to the room's changing humidity. 4) Be sure the humidifier's reservoir is full of water. 5) Unplug the humidifier unit. 6) Check the power cord. If necessary, repair the cord. 7) Remove the humidifier's cover panel. 8) Remove the humidistat and check it (as shown below). Replace it if necessary. 9) If it still doesn't work, call an appliance repairperson, take the unit into an appliance repair shop, or replace the unit. To check the humidistat, you?ll need a volt-ohm meter. A humidifier?s fan vaporizes the water in the reservoir and blows the water vapor into the house or room. If you need to check the fan, unplug the humidifier, remove the control panel, and lift the lid. Tighten the fan hub with pliers if it is loose; this should take care of rattles. If the fan doesn?t spin easily when you try to move the blades by hand or if it is still noisy, lubricate the motor bearings with oil. To establish whether power is reaching the humidistat when you know there are no problems with the plug or switches, unplug the humidifier, remove the control panel, and lift the lid. Test it with a volt-ohm meter set to the RX1 scale (or to K[omega symbol] or [omega symbol] resistance on a digital meter). Clip the meter to the humidistat terminals. The meter should jump if you turn the humidistat from high to low. If it doesn?t, you?ll need to replace the humidistat or return it to the manufacturer.
