Good morning fellow travellers, hoping for some guidance with the Thetford Loo electrics please?
Being inspired by Bucky's video of the Durba
camp, I rushed out and whipped off the van cover and did the usual preparation for hitting the dirt, but struck a snag when the loo wouldn't flush. Figuring it might be a fuse, I pulled the Cassette (Thetford C2) out and pinched out the fuse which checks out ok. Problem started trying to reinstall fuse - just cannot get it back in and to make matter worse - a piece of plastic fitting has fallen out of the assembly. (
Grey 'L' shape).
Degree of difficulty in seeing anything is about 9 - when I get low enough to view the assembly - I can't reach it - need to be a midget or a contortionist.
My question is, does anyone know if the wiring assembly which holds the fuse and wiring come out by unclipping it somehow? I don't wish to destroy the unit with my normal clumsy methods - but if the assembly does unclip, I will have a crack at it.
Has anyone had any success in this field please?
Regards - Phil

Google is not much help with this one.

Thanks Derek - Tried a few sites (didn't come across that one - very useful for what it does provide).
As often happens I think I am on a winner, then someone wants my card details for the info and I back off at that point.
Found a site 'Fardo' which offers what I hope are appropriate details, but had to 'Register' and am awaiting confirmation to go that next step.
Cheers - regards, Phil

I had a problem with
mine and as yours the fuse was ok, needed a mirror to get it back in.
The problem turned out to be a piece of grit jamming the pump. Had to pull it out and found the rotor locked. Gave it a little poke with the trusty leatherman screwdriver and it came free, gave it a shake and out popped a tiny piece of grit.

Notso - you're a genius. Thanks for that reminder, seems I had a similar problem some time back with ants blockage, lil beggars get in after the
water it seems.
Have to rush off to family functions all day, but will pursue that when I can get a free moment and post an update when done - might not be today though.
These senior moments of forgetfulness have their advantages - you get new experiences every day - again & again......
Thanks all.

Hi Phill just done that, there are two micro-switches in the device, the component marked 21-21 in the drawings is removeable by 4 screws and a wiring plug. then you can pull this part out to refit the fuse and check the switches.
Mine failed, the tab on one of the switches had broken off, (how???) and I resoldered it. The switch behind the fuse was a tricky one. It had fallen to pieces and needed a bit of logic to work out how it went back together. To get at the four screws, swing the
water tank filler out and the
grey housing with the wiring and switch is seen, two screws near to you, the 3-4th further back. First, remove the centre button on the flush knob inside the
toilet, there is a screw right down at the bottom of the centre hole. Pull the whole knob upwards.
The switch under the push button is the flush sw. The one near the fuse is there to prevent flush when the cassette is out.
Easy really, just a bit uncomfortable squatting down.
Send an email if you want a copy of the repair manual.

Hi Colcam - thanks for the feedback. As with others earlier, all very informative.
Derek's drawings are the only ones I have managed to get so far and they are now filed with the operating manual.
I'm fairly certain Notso is on the money with a blockage being the culprit and I will delve into that when I get to it.
I am dreading the prospect of undoing all those screws to get the assembly out, but it is looking likely as my continued efforts at getting the fuse back in have failed. At least now I am aware that it doesn't just 'clip into place' so I would have wrecked it with my usual tactic of giving a bit of a tug to see if that works.....
The annoying issue is - what is stopping the fuse from going back in? I didn't have that problem when I first got hold of the van and had to check it out. It is almost like an electrical switch has activated and the blade holders won't separate. So your tip is next on the list to get the switching system out and investigate further - then on to the probable blockage.
The saga continues and updates to follow. Thanks all - Phil

WOW Col - That is impressive, exactly the type of material I have been faffing around for a couple of days trying to get hold of - A very big thanks for that.
Having been involved in a hardware business in the bush years ago, a bloke would have killed for access to this sort of material. Way back, we were able to get good catalogues from the major firms (Sandovers, McLean Bros & Rigg, Atkins Carlyle to name a few), but when they fell away, there has been a huge gap in this type of material until this phenomenon called 'the web' arrived.
Now all a bloke has to do is learn how to get the most out of it.
I see what you mean by the file size - downloading now - colour pics and all - amazing.
Will be poring over this for some time now - hope I can Jag it.
Did the mirror, torch and fuse holder tool this arvo and had a real go at locating that fuse, but it will not sink home. Gonna have to pull the assembly out dammit.
Cheers & thanks
Phil
