Cassette toilet slide has jammed

I sorted mine the other year ..... using a CL with out toilet encouraged me to fix it when we got home.

I have a cast off   make up mirror in my tool box for such eventualities  

agreed, remove cassette and check sliding flap operation....

on our cassetre, the inside lever only operates a turning spindle....(which should still operate ok) and it's the spindle that engages with the cassette orange 'knob' and causes the circular flap to retract...you can test this by hand easily.

if not working correctly, almost certainly the toothed quadrant inside the cassette that's mis alighned....

however, if it works, it may be that the cassette 'sliding flap' has been put back on the cassette backwards, this can cause all sorts of jamming problems....

We had a problem with our cassette last year when the slide mechanism broke. I could have purchased a new one but I wasn't sure I could get into the cassette as the larger hatch can be difficult to get off. In the end I bit the bullet and ordered a Fresh Up kit which was delivered to site. I did keep the old cassette until we got home, where I had what I needed to open the hatch but in the end decided against it.

Assuming that your toilet is a Thetford, we had the same problem in our last van. Above the slider is a thin plastic cover which, over time had worn and split. This jammed the slider and prevented it moving fully across. I couldn’t see the point of this cover so I simply cut it off - with no detrimental affect and it worked perfectly thereafter.

We have a dometic in our new Coachman and although we can use the loo the slide is a devils job to get back! A child couldn’t manage it. I will try Silico spray and after that it’ll be a warranty job if they can’t make it usable.

Hi Merve. We have the same and the boss complained about that slider. I bought silicon grease, opened the flap and greased all round the seal. Also used Thetford silicone spray under the flap where there are two rods. I use this spray in the cassette hole as well. Solved the problem. She still doesn’t like the loo, why didn’t they fit a Thetford?

I had exactly the same problem with the so-called ‘top of the range’ Dometic fitted to our new Knaus Starclass. Plus, it leaked, the telescopic handle jammed in the open position, the wheels are too small to be of any use whatsoever and then the flush mechanism packed up altogether. In a nutshell, it was rubbish! Lasted all of 5 months.

Spoke to the dealer who was sympathetic since they had swapped a lot of Dometic toilets for Thetford across a number of makes of caravan for those reasons. However, they couldn’t do it as a warranty claim since it wasn’t a like-for-like replacement. It cost me £600 to have a Thetford fitted - but at least I now have a loo I can rely on. Plus it went in very easily without any evidence that it’s been changed.

I know I could have gone down the ‘not fit for purpose ‘ route but the chances of winning that argument against a company like Dometic was going to be time consuming if nothing else - and life’s too short! At least it’s now sorted.

Thanks waffler- I’ll get the silicone spray and give it a go. Yes, I think I prefer the thetford! 

£600? Wow! I never now pull my cassette on it’s wheels whether it was a Thetford or a Dometic. I went into a charity shop and bought one of those shopping trolleys you see ‘older people’ using- took the bag off it and the cassette fits perfectly. Dual purpose- when the loo business is done it easily reverts to a shopping cart again. 

Silicon spray after repair ,took mine apart ,if you rinse it properly after use ,therbshouldnt be any of last nights tea there ??
