Whirlpool hot water heater

The green light keeps blinking. Resetting does not help. Any suggestions? George33351, Welcome to the DIY Forums. Need a bit more info on this heater. Model # would help. Not familiar with the green light thing. Thanks. Originally Posted by George33351 The green light keeps blinking. Resetting does not help. Any suggestions? Assuming it's the electronic Smart one and it was working previously, if it's blinking quietly and you have no hot water, then the controller thinks there's no water in the tank, which could be a sensor defect. If it's making some hot water, and the blinks go with clicks (sounds like a turn signal), then you probably have a bad controller board -- which is easy to swap out. Get out your manual and write down all the information from the water heater (Serial #, model #, date installed, etc...) And then call Whirlpool at the number on the manual. They'll tell you what to do, and supply a replacement part if necessary (most likely under warranty).
