Duetto Electric Toilet Flush not Working

2004 model fitted with a C3 Thetford Cassette

3amp (I think) purple push in blade type automotive fuse inside cassette cavity blown; replaced but failed again,
possibly when flush is pressed

Any ideas anyone?

Hi there,

Three possibilities are:

1.  Short blowing fuse due to bare wire, loose wire or wet switch.

2.  Seized pump blowing fuse due to overload.

3.  Under-rated fuse replacement.  (Not likely.)

Sure there are many others but these are the ones I would check first.

Hope this helps.   

Best regards,
 

wire to the internal pump is likely perished and shorting.if it is the same as ours you can get at it thruogh the toilet roll cover on the bench.good luck g.

If you use (or have used) flush water additive, have left water in the tank and have not used the flush for 4+ weeks then it is likely the pump is stuck. If you move the impeller to loosen it up with a small screwdriver that will often get it working again. This is a very common problem.

It could of course be a seized pump or faulty wiring.

Fitted new pump, problem now resolved
Thanks to all for pointing me in the right direction

Great result.     

Thanks for letting us know that the problem is solved; but for future reference, what was the problem with the pump?   

Best regards,
 

The pump was seized up..

OK.   

Many thanks.   

Best regards,
