Meanwhhile think pump I have had problems with pump not working but it was because the pump impeler was stuck. Removed pump turned it upside down and turned the impeler with small screwdriver until it felt reasonably free rather than re-fix just dromped it back in the water to see what happened and hey presto it worked. Pump is accessed through the toilet roll cyo shaped holder housing which just pulls out you may need to use something to prise the housing out then vaselen around the edges before replacing makes for easy removal.
The pump is fixed by holding cage one screw. Lif out watch the tube to bowl doesn't come off or you'll get eye full of water if you forget to replace it. If that's not what it is and you find out what from Thetford please post it might help others and me if I get same problem.
TIP:
Never try replacing the pump cable back to micro switch unit you'll have to take the whole unit out to do that. Just cut the old wire and splice to the new pump wire using heat shrink sleaves obtainable in some auto shops. Watch the wire with thin trace colour [eg: white with black thin tracer colour] no matter if the wires are different colour make sure that you joint the wires with tracer colour on the old pump wire to the wire with a tracer on the new pump,then obviously join the two plain ones together.
