Tracker Posted November 5, 2012 Share Posted November 5, 2012 Try giving the cassette a gentle shake Dave - preferably part full of warm water (no not that - clean water) and with the blade shut as the floaters have been known to cling on a bit! You are right it is a magnet so perhaps you need to change your diet for one with less iron in it! From memory there are two magnets - one on a float in the cassette and one in a micro switch in the compartment and when the float rises through buoyancy (lovely mental image) and the two align you get illuminated so the cleanest thing is to get a magnet and check the switch first - but knowing your luck it will be Klingons on the cassette walls - knock em off Dave! It is a s####y job getting at it and full guidance can be found on the Thetford website depending on model but start by taking out the blade holder etc so you have a nice big hole to look into to see what is sticking and what is not!

George Collings Posted November 5, 2012 Share Posted November 5, 2012 From memory Thetfords warn against vigorous sloshing when flushing out the cassette as it can dislodge the magnets from the interior. 22 years of even moderate sloshing could well have overcome the most hardy klingon even though they are suckers for punishment. A bit of decorum please, don't go there Link to comment Share on other sites More sharing options...
Tracker Posted November 5, 2012 Share Posted November 5, 2012 It could also be limescale clogging up the float and Thetford do a cassette cleaner which has an ingredient that breaks down limescale without harming the rubber seals etc. Ordinary domestic limescale remover would probably work but I don't know if it would harm the delicate bits in the cassette.

T8LEY Posted November 5, 2012 Share Posted November 5, 2012 My brimming light stayed on earlier this year. Found it was a rusty fuse, located behind the cassette, causing the problem Link to comment Share on other sites More sharing options...
Patricia Posted November 5, 2012 Share Posted November 5, 2012 Had this problem some years ago as hubby had been shaking it too enthusiastically. Had to get hand in to sort it (no suggestion of removing the blade to make the entrance larger and guess who had the smallest hand ?!?! Link to comment Share on other sites More sharing options...

Brambles Posted November 6, 2012 Share Posted November 6, 2012 Quick question, if you remove the cassette does the light go out. Light out- fault is the sensor outside the tank. (Probably a reed switch operated by magnet inside tank.) Light stays on - fault in inside tank. Probably the magnet and float assembly stuck in the raised position and jamming due to scale rather than soil solids. Link to comment Share on other sites More sharing options...

We don't have lights..........just a colour'd gauge thingy ;-)....................I'm starting to think it might be bunged up with washing powder, as when we got back from our last trip I filled it with hot water and washing powder :-S Link to comment Share on other sites More sharing options...
derek pringle Posted November 6, 2012 Share Posted November 6, 2012 Hi Pelemetman, I would suggest just taking the cassette out and with the aperture opened give the inside a jolly good hosing. Would imagine it only takes a little toilet paper or debris to keep the float mechanism jammed in the wrong position. cheers and good luck derek Link to comment Share on other sites More sharing options...
Derek Uzzell Posted November 6, 2012 Share Posted November 6, 2012 I expect you have a Thetford bench C2/C3/C4 bench toilet http://www.bradtech.ltd.uk/products/Thetford-Cassette-Toilets--C2--C3-and-C4-Models.-T16348.html Spares are still available for these models, including spare cassettes, the Float Arm in the cassette that operates the contents-level indicator and the external contents-level indicator itself: http://www.bradtech.ltd.uk/products/Thetford_Cassette_C2_3_4_Holding_Tank_Parts.html http://www.thethetfordcentre.co.uk/magento/thetford/tf/level-indicator-for-c2-c3-c4-thetford-spare-parts.html A variation on brambles's advice... If you remove the cassette, does the "coloured gauge thingy" go from red to green? If it does not, then the fault may lie with the "gauge thingy". If it does, then (as brambles suggests) it's likely that the float arm in the cassette is stuck in the raised position. If the float arm had become completely detached from its mounting I'd expect the gauge to show green even if the cassette is filled with water as a test.
