Heater element may be bad

Rated voltage squared divided by rated wattage = ohms
Element rated for 240 volts and 3500 watts
240 x 240 = 57600
57600 divided by 3500 = about 16 ohms

Given that both elements are in working order, and the unit was filled before the elements were powered up. Here are a few other areas to troubleshoot.
Note: Electric water heaters contain high voltage, so care and safety must be employed when attempting any service or repair. Do not attempt any service, if you are not secure in your abilities.
Quality non-conductive gloves and eye protection should be worn.
First check that power is being supplied to each thermostat and then to the element when the thermostat is active. Make final temperature adjustments evenly, so as to not over work one element.
Next, check that trapped air is purged from the tank, by placing a catch pan under the TPRV (temperature and pressure relief valve) and quickly engaging it to see if air escapes, if it does then continue until only water is released.
Finally check to be sure that during installation, the cold water feed and the hot water supply lines were installed to their proper locations at top of tank.
Good luck...Let me know the results of your tests.

WHEN THE ELEMENTS R OHM'ED OUT, THEY SHOULD READ "0", INDICATING THERE IS CONTINUITY. ANY OTHER READING IS A FAULTY ELEMENT. U CAN ALSO OHM THE T-STAT 2 SEE IF THAT IS OR ISN'T THE PROBLEM AS WELL.
