93 fiat ducato heku 530 toilet question

Hello there, so I have just bought my first camper recently, I notice now that the pump doesnt come on when you push the button to flush the toilet, my question is does anybody have experience with this problem, can I get at the pump to test if its broke? Im in the leitrim/roscommon area.
any help would be greatly appreciated as im very new to all this and want to give it a go this summer.

thanks
david

It may be as simple as a blown fuse, on the thetford one in my van the fuse is in the compartment holding the cassette.

Thanks for the replys, gonna attach a picture,
Not sure if there is two pumps, would the pump be located in under the toilet area?

The round bit beside seat is toilet roll holder and does pull out,giving access to inside tank.Look up thetford web site and you can download manual and parts diagram for toilet.

I had problem with a thetford toilet it was a switch its located under the tank access through door remove waste tank look up there is a plastic cover held in 4 screws remove and you will find micro switch mine was all corded there are 2 switches on for flushing the other is activated when waste tank is in place if not there would be a mess used that one for the flushing and linked out the tank switch hope this helps
