If I can't get the power on off to work can I ever get E1 to reset?

we had the E1 error on our mspa after a water change. solution was a reset for us. plug in power, briefly press test and wait 10 seconds. unplug the power and wait for 10 seconds. plug in the power again and wait 10 seconds after which the reset button is pressed. then press the temperature button on the controller and briefly switch the air button on and off. after this the thermostat did it again. we were relieved that this worked, we had already searched the whole internet. this solution was copied from a model of lay-z

highly annoying issue error code E1. After hours
of fan operation, the error code E1 will appear on the seven segment
LED temperature display. This error code is intended as a reminder for
the user to clean the air filter. However, because the procedure
outlined in the user manual does not clear this error code as
indicated, and the appliance has a nonvolatile memory that cannot be
reset by simply unplugging it, the user of the appliance will become
mightily frustrated, standing in potentially sweltering heat watching
the appliance repeatedly shut down in the midst of operation with the
"E1" display flashing.

Believe it or not, that is what it does: if you unplug it to remove the
"E1" code from the display, and plug it back in and re-start it, it
will simply run for anywhere from a few minutes to a few hours, and
then merrily shut down again with the same flashing "E1" code.

So you will come home to a hot bedroom, living room, etc. unexpectedly,
and you will NOT be amused, as I was not.

Many people at this point, having put the manual under the canary or
some such, will simply return the unit and never buy another Sharp air
conditioner. But for the tech-savvy and search-adept, I offer the
following procedure to clear the nefarious E1 indication, and obtain

1. Power down the air conditioner using the "power" button on the front
panel.
2. Unplug the air conditioner from the wall socket.
3. Hold the front panel "power" button down and plug the air
conditioner in. Continue to hold the power button down as the machine
goes through a brief test sequence (fan & compressor each come on
briefly, etc). There is a "beep" sound at the end of the test sequence,
and the machine will be off. At this point, you can release the power
button.
4. Unplug the air conditioner.
5. Plug the air conditioner back in.
6. Congratulations! You should now be able to operate the air
conditioner normally for another 720 hours, but only if you followed
the instructions above EXACTLY.

Thanks for using fixya support..You have a wonderful day

E1 errors on most air cons mean a communications error. I don't know the codes for your machine but I would try a power reset first. Turn off the power to the machine at the isolator or meter box for 15 minutes and then try it again. If it doesn't work, I would suggest that its likely to be an indoor or outdoor board failure.

Good Morning Chris,

I see that you are receiving an E1 error code on your wine cooler, model# LFWC38F6LS, even though your wine cooler is still working. This could possibly be a false error code, caused by a miscommunication between the different control boards inside your appliance. I suggest resetting it by either unplugging it or cutting the power at the circuit breaker for 2-3 minutes. If when you bring power back to your wine cooler, you are still receiving the E1 error code, I suggest contacting either the manufacturer or your local authorized technician. Hope this is helpful.

-Best Regards-

The only real thing you can try is to unplug the unit or turn breaker off for about 30mins too see if it resets the board. The E1 F5 is a door lock error so hopefully pulling power from it awhile will work.

Sharp updated the procedure for resetting the E1 code.

1. unplug unit
2. hold the Power button while plugging the unit back in
3. keep holding the Power button until the unit beeps
4. unplug unit again
5. plug it back in and it should be good

Here is the updated user manual

F1-E1 - EEPROM Checksum Error - Disconnect power for at least 30 seconds and then reconnect.
Allow at least a minute after power has been restored and if error code reappears, replace control board (clock).

If your a/c unit is portable,and E1 code most always is "air filter cleaning time" or" water level to high ".
To reset air filter interval turn unit off at power switch then unplug.Hold power switch down while plugging in....unit will go through a short self check then beep.Release power button after beep.Unit should now be reset.
To reset water level....just drain some.....not all.
Most portables use water for increase cooling......so leave some in.
