Last Fall we bought a house, which was constructed in 2000. Just recently,
we've noticed that the hot water is not as hot as it has been since we've
lived here. (This is a "State Select" 40 gal. water heater. The style is
short and squatty, 32 inches high by about 20 inches thick.) I looked
closely at the heater last night, and I noted that both thermostats are
turned up just about as high as they can go.

I've done some reading here and there about changing the thermostats and/or
the elements. I have gone out and purchased two 4500w elements, as well as
the top and bottom thermostats. Before I "jump in" and start taking this
critter apart, I thought I'd post here for any tips that it would be helpful
for me to know. Thanks in advance for any insight that you'd care to offer.

Usually only one of the elements will burn out and then it cannot keep
up and get to set temperature.

I would cut the power and check the elements with an ohm meter. I
would bet that the lower element is shorted out and that it may be
covered with calcium carbonate if you have fairly hard water in your
area. Problem is you can't just replace the element, you have to dig
out the calcium carbonate, not easy through the drain hole.

I wouldn't replace anything that aint broke. I'm surprised that two
elements and two thermostats doesn't just about cost what a new heater
costs.

Many thanks for the reply, Frank. Yes, the water here is hard indeed. The
previous owner had a water softener, but they took it with them, as it was
not part of the purchase agreement. We've talked about getting one, but
just haven't seriously pursued it yet. I would be much in your debt if you
would amplify just how to use the ohmmeter. I have one, but haven't utilized
it in a long time...

I haven't shopped for a heater yet. These two thermostats and two elements
set me back a total of $62 and change at The Home Depot.

disconnect power

set meter to OHMS (may be marked with a greek omega symbol - ? )

disconnect the two wires at the element to be tested

put one lead of meter to each terminal of heating element (like how the
wires were just connected)

a reading of flashing, or 1 Mega ? (1 million ohms) or more means an open
element = bad

a low reading of 12 ohms or something like that = good

reconnect 230V wires to element you just tested or replace if bad

test other element the same way

reconnect power
