Hi Guys/ Gals, I,m having a problem with my Thetford model C-402C toilet, in that I can,t get the pump to work. I have power to the circuit board under the push on switch but I think I might have a faulty circuit board as I have 12v power from the black across all other contacts without pushing the button. So I disconnected the board, made up a short lead to power up the pump and I could hear the pump struggle to work. I have had a lot of black scale come through in earlier days when I used that pink stuff to add to the tank. Now I don't use it I don't have as much gunk coming through but the noise I am hearing now is consistent with a pump struggling and I believe it is either blocked with gunk or is there a filter on the inlet of the pump which is blocked. I tried to pull the pump out carefully but it seems to be caught on something and I am afraid of tugging too hard" is there something else I should be doing to get the pump out. I am confident that removing the pump will get whatever is blocking the inlet cleaned up but how to remove it --- please advise!!!
Cheers
Bill
