It looks like you have 2 issues here, so here are 2 solutions for you:
As far as the door not opening goes:
This is a
common problem, often associated with a momentary power failure when the
controller doesn't get time to reset and return to an idle state before the
machine gets power back and it gets "confused". Regardless of the cause, you will almost
certainly find that unplugging from the mains (Not just powering off on the
button, as some door locks have a sneak circuit, even when the power is turned
off at the button) and leaving the machine undisturbed for a full 20 minutes
will allow a reset, the door lock will disengage and all will be well when you
power back up.
Additionally,
on older machines with analog program selectors, turn the selector to an end of
program setting before you power it off.
Just a
thought here: If there is water in the machine above the level of the door, you
are going to get wet when you open it! The simple solution to this is to pull
the machine out and tip it back about 45 degrees, so the water sits to the rear
of the drum. NOW, you can open the door
and bail out the water without getting a wet floor
Regarding the failure to empty out water:
This is
almost certainly a simple problem with your empty pump filter being clogged. The
empty cycle is timed and if it can't get all the water out in time because the
filter is blocked and slowing the empty down, then it will fail safe and won't
step on to the final spin cycle with excess water in the drum. While it's
trying to get the water evacuated, you will probably see the machine doing a
slow tumble for up to 8 minutes and you may also hear the empty pump running
too.
You need to
locate and clean the filter. Depending on the model (not familiar which with
the model you mention) there is probably a round filter cap on the front of the
machine at the bottom (It may be behind a small door or hidden behind a clip on
panel on the bottom) Many models of this design also have a small hose to the
right of the filter cap that you can pull out, remove a plug from and drain off
any water in the filter before you remove the filter and get your floor wet, so
take a look for this before you remove the filter and get soaked.
OR
On Some
Hotpoint machines in particular, you will need to access the debris trap from
the back of the machine. If there is no
filter at the front, pull the machine out and you will see a roughly oval panel
at the bottom of the rear of the machine. Unscrew the 3 or 4 screws and unclip.
Directly below the drum, you will now see a rubber "Cup" like bulge in
the black pipe, with a plastic tube connected to a plastic pipe. The cup is
held in place by a large jubilee clip. Unscrew the clip, pull off the rubber
boot to expose the debris trap (A conical plastic cage with a ping pong ball in
it) Take out the ball and the plastic trap, clean out the debris and replace
the trap and the ball (Note that the cage may have a slot in it that locates in
the rubber boot, make sure it lines up, or it won't reassemble correctly). Now
push the boot back onto the fitting at the bottom of the drum where it came
from and tighten up the jubilee clip, making sure that it is fitted correctly (it
too may have a small slot out of it that fits around a protrusion on the bottom
of the housing).
Give the
boot a tug and reassure yourself that it is secure. Replace the panel on the
back of the machine and test. All should now be well.
