It comes up with a code of HC after completing the cycle and now i have water underneath the machine

check belt to motor if ok try under agitator the cogs are worn so replace them

This HC error code will appear at the end of the wash cycle to indicate that the hot and cold water inlet hoses are switched.
If the hoses are not switched it could indicate a problem with the Electronic Control Board.
You can try to rest the washer by unplugging or flipping the breaker to the washer for 2-5 min.

Restore power to the washer and try running a short cycle. This will help clear any irregularities that the control board may have encountered.

The water inlet hoses are probably removed and reconnected in reverse, and then trigger the HC error code to flash indicating the hot and cold water inlet hoses are reversed. Reconnect the water inlet hoses properly and start a cycle then let us know what happens next.

Hot/cold hoses were reversed, hence the HC code.

According to the Whirlpool "Cabrio" washer installation and maintenance manual, (Cabrio is the Sears Oasis) the HC code will come up when.

"
“HC” (Cold and Hot hoses switched)
This code will appear at the end of the wash
cycle to indicate that the cold and hot water
inlet hoses are switched. If an error code
does not appear, but you are experiencing
poor washing performance, check to see
whether the inlet hoses are reversed. See
“Connect the Inlet Hoses.”

After replacing the part to fix the F1 code, the washer (Oasis he) now comes up with a HC code. Also, even though the cycle is set for warm/cold, the clothes are coming out hot at the end of the cycle...and the cold water is hooked up and on. Any suggestions?
