I've been fighting with this hot water heater for a few days now and
it has boggled my mind, and everybody who I've talked to. It's a
Richmond 240v that's about 3 years old. So here's the story.
I came home the other night and the breaker was tripped (it is a twin
20 amp breaker). When I tried to reset the breaker it wouldn't lock
in the 'on' position. So I figured it was a bad breaker. Not too
uncommon considering the mobile home is 17 years old and it was
original. So I replace the questionable breaker and reset it. I
waited for about 45 minutes and nothing happened.
So I go to the hot water heater and notice one of the hot wire
connections was melted where the wire nut connection was. I cut,
clean, and reconnect the wires with a new nut. Waited for an hour,
and there was still no hot water. So I decide it's time to install a
I killed the power, drained the tank, and removed the elements. They
are 240v 4500w elements. I go to the hardware store and match up the
size and wattage. I got the whole kit which included elements, upper
and lower thermostats. It was like $7 more than buying the elements
only. So I come home, cleaned out the lime, and install the elements
and thermostats. I turned the water back on and filled the tank up
and waited... Guess what! No hot water. I later found out that I
made a mistake and didn't let the air out of the tank. So I figured
well this is going to be one of those $20 lessons.
I go back to the hardware store and get another set of elements and
installed them. I even checked the dip tube to make sure it was
good. This time I made sure that there was water at the pop-off valve
on top. Turned on the power, and waited an hour. No hot water.
Now I'm starting to get frustrated. I break out my handy multimeter
and start checking the voltages. I'm reading 120v at all the
connections and at both elements. I turned the power off and I'm
getting continuity through all of the wires and the tank as the common
I even ran another wire from my service panel to the water heater to
make sure I had a good power source. Still no heating.
So I'm completely stumped now and I was wondering if you all could
suggest something that I've over looked. I know it's POSSIBLE that I
got two bad sets of elements, but it's not probable.
I look forward to your responses so I can take a hot shower tonight.
