She wasn't using black tank flush, Just had a weight on pedal.
So no hot water was flowing.....all flow was via cold water line to toilet
Water heater GC10A-4E uses ONE set of t-stat/ECO to control heating for both electric and propane
*T-stat SHOULD have stopped all heating when water temp reached 140*F
*ECO (Energy Cut Off/HI Temp) SHOULD have shut down ALL heating when water temp reached 180*F and 'locked it out' plus triggered RED Fault Light
*T&P Relief Valve OPENS when water temp reaches 210*F and/or 150 PSI
Now did the T&P OPEN or just WEEP?
Both t-stat & ECO would need to fail in the CLOSED position for continued heating.......RARE.
Typically those preset snap disc t-stats fail OPEN....no heating
Did she have the RED Fault Light? and have to Reset ON/OFF for it to heat again?
IF T&P Popped Open and spewed water/steam then need to replace t-stat/ECO---come as a set
