CZ 2020C Flashing E3, how do I fix it?


If you place a small fan behind the heater where the controls are it should quit stopping on you. There is a small thermal sensor that is getting warm and shutting down your unit. Its a safety item.. but it also works when you need your heater the most. So place that fan and it will blow the heat into your room better also.

Check the filter. Some heaters will not work if the airflow is inadequate to prevent the elements from overheating. good luck.

E3 error on LIfesmart heater


Even after replacing thermostat and motherboard offered from company, my heater would trigger e3 error code and shut off. After several (maybe 100!) different attempts to plug in and operate, here is what worked for me!
Depress the power button on the heater while plugging in to wall circuit. Continuously depress power button. It will run through a test cycle and attempt to start. Keep depressing the power button as the heater tries to start, then shuts down with e3 error. While the power button is still depressed, unplug the unit from the wall. When I plug back in the wall the E3 error is gone. Good luck

Garrison tower heater flashed E3 code?


hi there, i just ran into the same problem i think i have the solution:

the E3 code is a "fall down" sensor shut off, what i think the problem is the internal sensor for when the unit falls over and shuts itself off is really sensitive. i had mine on carpet and it was acting up quite a bit till i wiggled it and put it on a more level surface.

hope this helps

Is there a quick fix to a flashing e3 on a Danby DDW497W?


Refer the user manual for your dishwasher. Error codes are given on page 7.

e3 means the heater is not working or the thermostat (which checks the water temperature) is faulty.
Not sure there is any quick fix other than to replace. If the heater is showing some reading on an ohm meter then it is likely the thermostat is faulty. In any case it will be easier and cheaper to replace the thermostat first.

You will need to call Danby service closest to you for advise on getting the parts or servicing it.
Please rate this solution to help fixya serve you better in future.
