So my inlet valve burst and i bought a replacement. Turned off my kitchen b
reaker, removed the old valve and as i was installing the new valve the wir
es touched, sparked and went dead. Apparently the washer wasn't on that cir
cuit. Apparently. I finished connecting the terminals and water but when i
hit the power button all the cycle lights turn on and it just humms. Hittin
g the start cycle has no effect. Anyone know what i borked?

Could that model number be a h and not a k?

This doesn't quite make sense.
The dishwasher was NOT in the middle of a cycle, correct?
(even if it was still "plugged in").
So, there would be no reason for there to be "power"
(i.e., a voltage difference between the two wires)
to those connections. As such, no reason for a "spark".
(unless the valve has THREE terminals and an "open"
and "close" coil -- doubtful)
Were any of the wires GREEN (safety ground)?
Are you sure you didn't touch the chassis, instead?
You may have only broken the new valve; or the "driver" that turns
it on (i.e., supplies power to that coil).
It is possible that the unit is waiting for water that is never going
to come (because of one of the above problems).
Does the manual give you a "cheat sheet" to evaluate any error
codes? (I'm reasonably sure it IS indicating an error to you
but in a cryptic way)

I want to understand the reported observation:
"the wires touched, sparked and went dead"
to better posit likely problems. IMO, there shouldn't have been
ANY potential ("voltage") across the coil -- unless it was
supposed to be ON. I can't understand why it would be ON if
it wasn't actually trying to run a cycle.
If, indeed, it was "off", then something else was responsible
for the sparks.
It is unusual for any modern device NOT to report some sort
of error information -- though the actual indication might
be obscure (count blinks, notice odd combinations of lights,
etc.). Error message/code gives you an idea of what the
device is "missing" (expecting but not detecting).
He claimed the leads touched. That implies that the other lead had a
"return path". I.e., there was potential ACROSS THE COIL at the instant
the spark was drawn. That should only happen if the dishwasher wanted
the coil to be energized. Which should only happen during a cycle!
Possible it was on wash/rinse cycle. Any cycle can be cancelled by
hitting reset button. Our DW is front control panel model.
Under the start button there is little marking, "reset 3secs." meaning
hold it down 3 secs. to reset after pushing power button. It is
mentioned in the owner's manual as far as our Bosch model is concerned.
