Thetford C260 blade wont open

[JQB]

Well this has ruined my evening.

Went to the loo and pulled the lever back and it wouldn't open. I noticed though that the lever only goes half way back also. I somehow got the cassette out (it didn't want to come out). Emptied it and tried to put it back in. It goes in but the blade is still shut and wont open inside the van. In the end all I could do was take the cassette out, remove the cover to the cassette, refit it and then manually slide the lever back inside the loo with my hands. So now the empty cassette is in and the blade is open but permanently. Obviously this is not ideal as even with the toilet lid down its going to smell but at least we can use it. Its pitch black so that will have to do until the morning but I'm hoping someone will have some pointers as to what we need to do to fix it.

There is definitely something wrong with the lever though as it only goes half way back and forward.

Sound as if the cogs which can be viewed inside the cavity in the van where u slide the cassette in or out have jumped have jumped, maybe due to repeated use and wear. Best to be gentle with the open and closing lever on the front of the loo i guess, once cogs readjusted that is.

Thats what we thought at first and they were a bit out of alignment which I corrected but the culprit was the Thetford cassette mechanism itself. Now replaced.

Anybody bought a silicon spray that does in fact stop vents and the and PVC sliding door seals from sticking? Iv'e bought pound shop stuff and wd40 branded but they don't work very well at all

Ill have a look when I eventually get the van out as thats where my silicone spray is but its very good stuff. Not from a pound shop though. I generally using it for stopping creaks or keeping moving parts lubricated where you cant use stuff like WD40 or oil.
