Can't get my green light to blink to reset my hot water water heater

Please tell us the brand and the model number of your Water heater, Thanks.

Did you read the instructions pasted on the water heater right above the thermostatic valve ?

It is important that you TURN the small black button on top of thermostatic valve to OFF position... there is a small cut out in that button and that MUST align with the RED button positioned right next to it... then... PRESS that red, pilot lighting, button ALL the way down ( it should be pushed through that notch in the black button ) and keep holding it down ... WHILE lighting the pilot. Once the pilot is LIT, keep the red button PRESSED for at least 30 more seconds - then slowly release it. If the pilot dies - repeat. Try again
