Hi,
I have a Rudd electronic Water Heater, might be 5 years old. When I open the hot water, I got the hot water right away, and extremely hot. However, it won't last longer than 5 minutes.
So I adjusted two panels, make the thermometer to point to 140 degree, instead of 170. The temperature of the hot water is lower now, however, the water still does not last longer than 5 minutes.
What's the problem? Is it fixable? Do I need to replace it with a new one? :confused:
Thanks.
Jim.

One of two things are possible.
1. One of the elements is burnt out. Probably the bottom one as it does the most work. It keeps the water hot at all times. The upper kicks in when it needs to boost water temp.
2. The dip tube is broken. This tube is in the cold water supply opening on the heater. It takes the cold water to the bottom of the tank and thus pushes the hot water out when called for. If the dip tube goes bad then it "short circuits" the water and it mixes at the top of the heater and you get "warm" water.
Both are DIY possible.Make sure you turn off the power before disconnecting (or touching) any wires. My best guess would be the element. Good luck.
