How to test water heater wires

Do not touch electric water heater that is wet. Turn Poser OFF.
Water heater cover

Turn power OFF

Open covers on water heater

Remove insulation and plastic protectors
Foam insulation might need to be cut back
Power is OFF

Tighten all screws very tight against copper wire
Look for signs of high heat and burning.
Look for melted insulation on wires. Look for burned or blackened wires.
Use nose and smell for burning.
Test electricity
Turn power ON
Power is ON

Test for 240Volt across top two screws on upper thermostat

Turn Power OFF to conduct rest of tests

If tank is not receiving 240Volts, test electricity to water heater
Avoid electrocution/
Multimeter
Tape multimeter leads to wood
Stand on dry boards
Do not touch metal
Wear dry clothes
Do not touch wet water heater
Melted wire
Look for burned or melted wire
Replace part
Cut back wire
Test continuity of wire/ or replace wire
Inspection of water heater finds burned wire:
Power is OFF
Action:
Replace part that burned wire is connected to.
Test continuity of wire that has been burned.
Replace wire that has no continuity.

Multimeters at Amazon
Set multimeter to read ohms
How to test continuity of wire:
When burned wire is discovered/ or bad wire is suspect
Power is OFF
Set multimeter to read ohms.
Disconnect wires from each tank part. For example disconnect wire from thermostat and disconnect other end of wire from element.
Test #1: Put tester leads on both ends of wire.
If test reads ohms, then wire is good.
Test #2: Test each end of wire to bare metal part of tank.
If test reads ohms, then wire is shorted and must be replaced.
Tanks with foam insulation may need to be replaced.
Test wire between water heater and breaker box.
Turn off breaker.
Remove wires from top of heater.
Re-test wires on tank.
Test wire from breaker with breaker off.
Test for continuity between each wire and each wire to ground. There should be no current flowing between any of the wires.

Melted wire will pass continuity test.

If ECO keeps tripping, and thermostat is good,  and water is not overheated, then replace wires inside tank.
Breaker tripped, and now ECO is tripping:
Water heater had leak, and now ECO is tripping:
Quick answer: Replace thermostats and test elements
Inspect for burned parts and and loose wires: Replace burned part.

ECO trips when wire is partially melted due to short or electrical overheat.
Wire can no longer carry element wattage, causing heat that trips ECO.

This happens if water heater leak caused short. Or if circuit breaker tripped. Or if water heater had a fire. Replace wires.
New water heaters with foam insulation might require replacement.
Water heater element Wire size too small for element.

Installed new element, and now ECO is tripping:
Quick answer: Replace thermostats and test elements
Inspect for burned parts and and loose wires: Replace burned part.

ECO trips when wire gauge is too small for element wattage, causing heat that trips ECO.
This happens if replacement element has greater wattage than shows on label on side of tank.
Compare rating label on side of tank with wattage rating printed on end of each element.
