No Ground? Exploding Dishwasher > There's a little voltage on my line.

There's a little voltage on my line.

You need to call either an electrician, or your cable company and get that fixed before someone gets hurt or equipment gets fried. That is very dangerous.

What that means is that the two pieces of equipment are at different ground potentials. All electrical equipment in your house should go to the same ground.

That is why most of the time, you will see the cable ground, and the telco ground tied to the electrical ground of the house, to keep all the equipment at the same ground potential.

I'm sure a little over exaggeration was done, but the sound this could make is unbelievable. Although I was just a child, as such everything seems larger and louder than it is, the POP that the refrigerator, TV, and Radar Range (it was that long ago) made would easily have been described as an explosion to me. What happened, was my neighbor's line was struck by lightning. For whatever reason, I don't know for sure, a surge came through our house. Back then, everything was grounded, but it was not required that the grounds be connected or that all had to share the same ground. Our phone line had a better ground than anything else in our house. After the refrigerator popped, the TV clicked and started smoking, and the radar range started sizzling, the phone on a table in our living room caught on fire due to the surge trying to find a way out and entered the phone lines through the answering machine; since the phone had a better ground than our power line, the surge went through the circuits with the above appliances before making it's way to the answering machine and then out to the phone's ground. The buzz and bass sounds throughout the house were deafening as the surge raced through the power lines and then the phone lines. All of the affected cables were melted, it was very easy to trace the path it took.

Without a grounded outlet your surge suppressor is what is putting the 70V on the ground line of anything connected to it.
Since the cable is grounded guess what?...Bzzzt

if it's a UL listed surge suppressor (or CSA OR ETL for that matter, they all use the UL standard) there is no way that it can put any voltage on the ground. the design wouldn't make it through the first day of testing that way.
