I have had the AE125 electric Powerstar for a little over a year now and it has NEVER put out really hot water. Just for a couple of seconds and that is rare!!! We have it turned up all the way. It has always clicked when the hot water is turned on also. Now we have NO hot water at all. The electrician is gone that installed it and we can't seem to get anyone that is interested in coming out to fix it!!! PLEASE HELP!!!!!!
