How do I clear or fix an E4 error code
I get an E4 error code and have unplugged for 24 hours and restarted but still get E4 code and unit automatically shuts off
GE Profile Tri Temperature Water dispenser E4 error code from your manual states:
Dispenser has experienced a sensor failure.
Unplug for 24 hours and let control to reset.
Re plug the unit in and repeat start up and operation adjustments.
Repeat if required. (( however, some failures may be permanent)).
Could be a faulty board/ sensor issue inside unit, have a good repair tech, have a look, diagnose and estimate repair. Good luck

We just installed a garbage disposal. There is a knockout plug on the body of the garbage disposal that the dishwasher drain line attaches to. We’ve had this problem before and a plumber told us about it. This time, we forgot to knock out the plug and it caused our dishwasher to send a error code of E-4. Once I knocked out the plug and reconnected the drain hose to the garbage disposal the dishwasher code remained on. At this point the only thing we’ve seen we can do now is disconnect the power to the dishwasher to reset the code. So far no luck but we will wait a full 24 hours. This is a new dishwasher. I would be very surprised if it failed one month into use.
Technically, the E4 error is not an error at all. It actually tells you, your unit is going into defrost mode. That does, however, mean that something has caused your unit to get too cold. A broken temperature sensor can also cause your AC to enter defrost mode.
Tips to fix-
It does not matter if you are operating a portable air conditioner, mini-split, or central HVAC. Your system is complex. Many components depend on each other.
If one is not working properly, the unit can quickly freeze. Older systems that lack current technology could freeze over and cause a lot of damage.
Ice can form on your indoor or outdoor unit, on the AC lines, and in the ducts. The E4 error code does not signify what is causing the unit to freeze or get too cold to operate without causing damage.
There are home warranties that cover mini split air conditioners and electronics policies that cover portable air conditioners. In hot climates, it is vital to have a way to cool your home.
Air conditioners usually break on the hottest days because they have to work hardest to maintain a comfortable ambient temperature. Do not get caught off guard on a day when you need your AC the most.
