Make sure the power is off before you look at or check any electrical device, you need the multimeter and a voltage tester you can check yourself. Remember to call emergency plumbing if you have any issues you are uncertain of how to tackle.

If you suddenly find you don’t have hot water, it could be
that one of the elements in your hot water service is at
fault. Electric water heater element testing is one way to
determine if one or both elements have failed.
There are a few simple things you can do:
Check your circuit breaker first and make sure it hasn’t been tripped.
The electric water heater should be on a dedicated two pole circuit in
your breaker box. See if it has tripped – no power – no hot water. If the
breaker hasn’t been tripped you will still need to see if you have power
in the hot water system, shut the breaker off for the water heater.
Many thermostats have a reset button – you will need to shut off the
power and remove the covers to reset them.
Only perform a water heater element test when the power is OFF.
Electric water heaters have a powerful current in them, and you can be
seriously hurt from a shock. The current can also ruin your testers –
make sure the power is OFF.
Checking your water heater power is a must on an electric water
heater, unlike gas water heaters, electric units don’t work when the
power is off.
Remove the covers for the upper element and thermostat, remove the
insulation and protective cover, the two hot wires should be at the top
of the thermostat. Turn the power back on and CAREFULLY use a non-
contact tester to check for power. Make sure the tester is working – so
check it on something you know is ok first. Do you have power?
MAKE SURE THE POWER IS OFF BEFORE YOU LOOK AT OR CHECK ANY
ELECTRICAL DEVICES, AND REMEMBER TO CALL EMERGENCY PLUMBERS IF
YOU HAVE ANY ISSUES YOU ARE UNCERTAIN OF HOW TO TACKLE.
