Cassette toilet fault

[Herbenny]

Any ideas please ? We can’t close our cassette toilet there seems to be a faulty catch somewhere and it’s difficult to take out cassette .. I absolutely can’t believe the price they are to replace

You cannot remove the cassette until you close the blade.
I would put on a pair of true touch gloves and try feeling for the blade to see if you can close it manually. To do this try pulling gently at the blade, whilst trying to slide the lever. Good luck.

That would be my guess too, had it happen when Liz had a last tinkle and felt pressured as I was waiting to empty it, and she didn't close the blade, as far as I know there can't be anything else that would stop it coming out other than the catch under the handle at the door.

Get yourself an aerosol of silicon lubricant or mould release spray in any crevice that will take the little tube.

If and when you get it out liberally spray the rubber seal and any moving part. Good luck.

If you can jiggle it in and out a bit and (get someone else it) jiggle the open/close knob that might help.

Once out you used to be able to buy replacement parts for the mechanism inside the cassette. It's a bit messy and fiddly (especially if you have big hands) but you can find an exploded diagram of how it goes together on the net. I would replace the big donut washer anyway.

Depending on which model you have, this might help:
First (as others have noted) you need to release the catch at the base of the cassette before the cassette can be removed.
Second... ours is a C2 and the blade is turned by a rotary knob, which is secured to the fork by a single screw. If that screw has released, the knob won't turn the fork/blade and the cassette won't be able to be withdrawn. To fix, just pry out the cap in the centre of the knob, seat the knob on its splines and with a long crosspoint screwdriver re-secure the screw.
If it is this, to remove the cassette in the first instance turn off the electricity (so the flush doesn't operate), push the knob in as you would to operate the flush and turn the knob to close the gate valve and align the blade ready for cassette withdrawal.

don't assume it's the cassette it could be the toilet mechanism when cassettes out does toilet flap open an close freely

Thank you all for your advice .. I will try and sort it tomorrow abd let you know how I get on.

My first cassette started to jam as the bits had some wear, as others have said spray with a Teflon can, and then gentle persuasion is required.
In the end, I had to replace mine as the bits had worn too badly and jammed half the time.

My van has a C200 toilet, when I had a problem like this it was because the small screw holding the mechanism in place inside the door hatch had fallen out, unfortunately you cannot get to it without removing the cassette but once it was removed I could see where the screw should be, it was at the top where you could see the hole of the toilet bowl, at the side was a plastic lever with a hole for the screw, I put it back in and still perfect 5 years later, if this isn't your problem there are videos on YouTube giving instructions of how to overhaul the cassette itself

 

[Tezza33]

Any luck with this yet or have you nothing to go on?


This video is similar to mine, not identical and mine is a lot cleaner but you can see the mechanism that I had to tighten so the process was identical

I bet Herbenny thought hard about that piece of advice?

I think Dick might have sent the thread awry.
