Thetford Cassette C-200CWE will not flush.

Recommended Posts

Hi, my Thetford Cassette C-200CWE will not flush. How do I get to a) the 2 AA batteries, and b) the pump to check if they are serviceable?

That will give you the manuals and FAQs 

 

I recall no AA batteries in the CWE (electric flush, the pump using power from the 12V leisure battery)?  But would be in the cassette holding tank bay if there is a battery holder on wire and be for the 'full' led (was there on a manual pump 200 I owned).

 

Access to pump is via exterior door after removing holding tank.  It unclips from the 'roof' area on RHS nearest door. Be gentle.

Thank you Rodders53,

I have already downloaded the manuals as you described, and the diagram does show a battery holder. Perhaps my cassette is connected directly to the 12v leisure battery, in which case I shall check the circuit.

I would also like to check the pump to see if it runs, but it is difficult to find a way to it. You say it is accessible through the outer door, but another member says it is accessible by removing the push button console from inside the caravan.

As the console is kept in place by a very sticky sealant, I am wary of disturbing it and causing a leak.

I will be able to investigate further next week when I return to the caravan in it's storage compound.

My bad memory probably. 

Confusing the C200 which I definitely had in manual pump form.  Battery pack was on wires tucked onto a 'shelf' inside waste cassette compartment.  With a C250 which came later (now the C260 style).

 

It's quite possible that access is made via careful peeling off and removal of the top press-button switch?  https://www.caravantalk.co.uk/community/topic/131702-thetford-c200-cwe-fuse-blowing/ and YouTube may help you more than my poor memory!

 

https://www.caravantalk.co.uk/community/topic/29449-thetford-c200-cwe-toilet/ is another old thread here that explains how to get to the pump.
