if you are looking back in follow steps below to access thetfords free repair pdf downloads.
does sound like microswitch stuck on or pump short out.

uk & europe www.thetford-europe.com
australia www.thetford.com.au (even get request from australian campers)
australia site has stockist list.

home page select english {if in australia forget this selection it doesn't come up)
select customer service (top line)
select products from top line
select bulit in or portable which ever applies.
select user information from list on right.
select repair instructions from list on right
select built in or portable which ever applies.
select select your toilet series model number from right list.
you will now be in the pdf listings for your range of toilets just select those that apply to your toilet and down load them they're free.
as you go through watch for 'ask thetford' on left listings
you may not find what you want and you can send them a message.

for safety reasons which i agree with thetford do not offer repair advice for fridges. refer to service centre

Could be the switch. Could be the wiring, but either way contact is being made between the switch wires.
Put a meter across the 2 terminals of the switch ( wires off) and if you have continuity then the switch is jammed in the on position. If the switch is working properly then follow the wiring to find the short circuit.
You can have a look at the exploded diagram for your cassette on the thetford site just look for the spare parts page and it will come up with an exploded diagram giving you the layout of the parts.
