Our 60 gallon electric hot water tank only had enough hot water for
one bath, so the plumber drained the tank and replaced a defective
heating element.

We had enough water for 2 super hot baths that night, then ONLY cold
was left. And the tank starting leaking on the floor that night,
although dries up during the day.

The plumber next replaced a gasket thinking that would stop the leak,
and pressed the reset button. We again had super hot water for 2 baths
ONLY that night. We pressed the reset button ourselves before bed, and
again had leaking water around the tank overnight which dried up
during the day.

The plumber came back and replaced the thermostat. The water isn't so
boiling anymore, which is good, but we still have a problem with the
tank shutting itself off after the evening baths, plus there's water
on the floor in the morning.

When the tank's panels are off i can see that the yellow insulation is
wet. I'm assuming this is what keeps shutting the tank off forcing me
to reset every evening.

What do I try next? Do I need a new tank? Is the water I see just
leftover water from the bad gasket/super-heated water problem? Will it
dry up on it's own after a few days? I assume the water is what's
shorting the system and shutting things down. But why is there only
water on the floor overnight and not during the day?

Anyway, advice I could bring back to my plumber as a suggestion (or to
a new plumber) is appreciated.

Thanks;
Les

Approximately how old is this water heater?

I'd get a new plumber... a water heater is a cheap replacement ~ $100 bucks.
3 wires to connect & 2 pipes.

Without seeing it, or knowing how old it is, it's impossible to give
much advice. If the tank was properly drained, there should only
have been a tiny bit of water when the element was removed, not enough
to get the insulation soaked with a lot of water. Did you check for
any visible leaking around where the element was replaced? And even
if the insulation is wet, I doubt it would cause the circuit to
trip. If the insulation is wet, I'd leave the access covers off
until it's dry and make sure the wet insulation isn't on top of bare
circuit contacts.

I guess since you're already into this guy for an unknown amount, you
should call him back again. But I wouldn't pay him anymore unless
it's clear that whatever is going on is due to some other problem
cropping up that he isn't responsible for.

The tank is roughly 5 years old... I read elsewhere that if the water
is super hot (and it was), that can cause leakage. The thermostat was
apparently shot, but even after replacing it I assume the damage would
have been done and any water that seeped into the insulation would
have to evaporate. it's just weird that I only get seepage overnight.

I think it's either time for a new plumber or a new tank.
