It's ten years old, it just stopped heating the water, and I'd like to try to repair it myself before paying a repairman. But where to get the part in a reasonable time frame? Home Depot says they don't carry it.
It's a Craftmaster model E1E4ORDO45. If I have to buy a whole new one, I'd want a plug-in replacement. I don't want to fiddle with welded copper pipes.
