Unit in defrost too long. Check defrost sensor cable for proper connection. If error persists, sensor assembly may require replacement. Contact service.

Simply means hot water heater called for heat for 1 hour and never rose in temperature or reach stepping, unit automatically goes into lockout. I would reset power

is it an electric or gas or oil fired. Er3 means it is not getting up to temperature within the required time. Electrical - element bad. for oil or gas, no ignition or fuel supply.

Hi, If you have the book for this system, then go to the problem solving to the rear of manual. This will tell you what code ER3 means, and what you need to do to correct it.
If you dont have the manufacturer's book then try to down load it!.
All boilers and water heaters have different fault finding codes, so can-not give any more info, unless you can tell me the exact problem.
Thanks Paul.

Er3 means that the water is being heated for more than 1 hour without reaching the set temperature.
Need new aquastat.

error 3 is that the cd is scratched and error 6 is the cd has been inserted upside down

We had this problem and could not make it go away by refilling, jiggling the float and so on. All the controls appeared frozen during this time.

But unplugging the humidifier for 5 minutes and plugging it back in seems to have fixed it -- no ER3 message now (fingers crossed!0.

This sounds like the float switch may be stuck - giving an error message - usually these are not too hard to unstick - it is often a cleaning issue - the manual should show you where the float switch is and how to check it, but if the error message is not listed in the manual, if you are sure it is the correct manual then I would expect it to be a technicians job, else they would list the error message.
