Question about Water Heaters
Not sure how to remedy this as I have no Instruction Booklet. However, I disconnected system then rebooted it. Seemed to do the trick!

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.
