Our water heater stopped heating the water recently. Luckily two men in our family took it upon themselves to help us. One checked with where we bought it but they had no info on the warranty because we paid cash. Then he checked with the manufacturer and they said replacement kits were available. A part was express shipped overnight and we had it the next day. This didn't solve the problem however and the manufacturer was called again. They shipped another part and that fixed the problem. Our water heater was only a year old and had five years left on the warranty. So nice to have hot water again. Sorry I can't be more help - just share our experience.
