What happens when the electric water heater doesn't produce hot water?
If the valve is a problem, may lead to water, so there will be no hot water. Next is the water heater internal scale is too many, causes the jam. Do you feel the plug blown out when you blow it in? If yes, that should be for you (front water heater maintenance and cleaning).
First check the pressure relief valve (also called the safety valve, or Dan Xiangfa) features: when the water heater heating when the internal pressure increases, when the pressure exceeds the safety of relief from the security hole dripping, but also to prevent cold water after heating expansion back to tap water pipeline.
. Finally, you can see is not the problem of the water inlet valve, close the inlet valve first, open drain valve (the thin pipe) to cold and hot water mixing regulating switch to hot water from a nozzle at the end, blowing (only a blow on the line), then pipe hot water flows out, to have been placed in hot water water heater. Then heat up the electric water heater and try again!
