    My Thetford C-402 packed in 6 weeks ago ( fitted to my not yet 1yr old Eldiss ), just stopped flushing completely, dead like the dodo !, checked the fuse and connector block in the cassette compartment, all fine, one dealer suggested that things may have "gummed up " between one outing and the next and to use a strong solution of Milton in the flushing tank, leave overnight and try again, did this but no joy,
    It really is inconvenient not being able to flush the bloody thing after use and having to pour a solution down the loo by hand,
    Despite the van still being under warranty, Eldiss are of no help whatsoever, referred me to the dealer who supplied the van, who are, due to me moving home again, a 7/8 hundred mile round trip away, bit far and a bit too much to spend on fuel don't you think, to rectify a small fault,
    I did contact the supplying dealer who mentioned that they had a few returned with the same problem, gave me advice to remove/dismantle the flushng mechanism panel, check it with voltage tester, which I am quite happy to do, but, of course as soon as I touch it, the warranty is void, catch twenty two situation I guess !,
    I have contacted a couple of Eldiss dealers up here in Scotland, who, quite frankly, do not want to know, then emailed Thetford for their nearest dealer , but no reply, so I am a little pissed off, I feel I an going round in circles getting nowhere
    Is this common for Manufacturers to fob off faulty products after purchase, and offer no help or assistance with their ranges, when things go wrong, makes me wonder why I bothered buying new !, :cry: :helpsos:

    Hi Beerdrinker, we have the Thetford C-250 but get the same problem if someone pushes the flush button too hard.
    If yours is the same as ours then you need to pull the flush button panel away from the wall and you will find there is a circuit board with a micro switch behind it which just needs to be pushed back into it's holding clips and carefully replace the panel.
    Hope you will soon be flushed with success :thumb:

    Thanks Brian, Although mine is a different model i guess the principals will be similar, so will have a go with your suggestions,

    Good luck with it Ken, I hope it solves your problem......let us know if it is the cause of your flushing failure as I understand it is quite a common fault.
    I have been trying to work out a long term fix to stop it happening again but as yet don't have one.

    I have exactly the same problem, tank full of pink stuff, just hope it doesn't freeze too hard before I get it fixed!

    It was resolved by removing the cover as described previously, then getting your hand down the tank to locate the pump and bringing it into a position to work on,then with a thin screwdriver turn the impeller, just a flick, it should free itself easily,

    The impeller tends to adhere to the side of the pump after being laid up and not used,
    not necessarily due to a long lay up,

    Hope that sorts it ok,
