    This MH has been standing idle for an unknown amount of time due to last owners ill health.
    Our friends have filled the bowl and now cannot open the blade. I would imagine it is stuck due to lack of use and not being lubricated.
    We may have to ladle out the contents I suppose :eek: but suggestions please for loosening the blade
    Thanks

    Just press down on it around it's edge, beware of splashback though !
    Failing that, pull the cassette out and undo the screws that hold the seal in place, it'll come away then.

    Seals can stick, hence why when left for a while it's always better to leave the flap open a little (y)

    Poo glue is like Uhu, a good whack with a blue shoe is needed to unscrew.

    Rubber seal has stuck to plastic blade.
    Removal of seal may be the only solution and fit a new seal at the same time as there's a chance the lip on the old one may tear on removing from blade.
    I doubt it will ever seal properly again anyway even if it doesn't tear.

    Noo - you'll have the bowl contents to clean out of base if you do that. Use something (a stick?) to press hard on the centre of the blade. You'll feel it free off.

    Struggling to understand how they could fill the thing if the blade was stuck. But in any event they should still be able to empty it through the spout. Or have I misunderstood the problem?

    Yes you’ve misunderstood.....
    The cassette did have some contents but that was over a year old from previous owner .

    The toilet bowl was filled overnight with combination of wee and flush water by our friends.
    Then in morning I was asked how to get it out of the bowl and into cassette because their lever wouldn’t work. That was when I discovered their blade stuck to the seal. :eek:
    The funny thing was, when I asked the husband to press down on blade as per one of the earlier suggestions in this thread. What put my hand in there! It’s only your own wee says me. I even made him squeeze out the paper and put that in bin lol.
    Then when enough of a gap had been formed, the liquid drained into cassette and we were able to remove the cassette.
    Then he poked at the dried brown stuff on the blade with his finger. Don’t do that. ! I said
    Why?
    It’s dried on poo. !
    You should have seen his face.

    poo is only part digested food. people are so squeamish about it, but you happily wipe your own bum daily when its fresh and warm
