Upon arrival to the location, I met with Ana, Carlando was not present at the moment. She explained she had some work done recently in the home, and they had to shut down the main valve and after they turned the main back on, they just haven’t been getting any hot water. She also stated she flipped the breaker in and off a few times but nothing changed. I told her I’ll check to see if you’re getting any power to the unit. It turns out she’s not getting power to the water heater, nor to the wall connection. When I looked at the breaker, I noticed it was a 20 double pole amp, which should be a 25 amp for a 4500 watt unit. I explained to Ana the situation, and she said it made sense because from the beginning they would run out of hot water, and it would never stay hot enough, just warm. I advised her she would need to get an electrician to change out the circuit breaker.
