I have had an intermittent fault with the electric flush on the C2 Thetford toilet fitted in our van. I have already changed the pump and flushed out the top tank so when it happened again last trip it was bothering me. And decided it had to be the switch or electrics playing up rather than suspecting a second pump.
Working from inside take off the cover cap on the flush knob and with a long pozi screwdriver remove the screw down inside the shaft and lift the knob up and out.
Then working from outside pull off the white plastic cover
Undo the 4 pozi-screws 2 at the front 2 at the back are a bit hard to get too.
Now drop down the grey plastic bit it has the flush wiring and switches in it.
Disconnect the 2 plugs and the unit is free
No need for any electrical tests here I can see the problem already.
The fuse holder is so corroded it won't work.
So an electrical repair to that and the whole lot can be refitted and job done!
