Hi,

Just set my caravan up for the first time this year and the toilet won't flush. It's a thetford bench toilet.

When I press the flush button it is completely silent, I have checked the fuse which is fine and there is power to the switch. I have also checked that the switch is working and when pressed there is 12v on the secondary side. I can't see how to access the
pump, but have been able to get into the water tank (water looks clean) by removing the switch and lever. There are 4 screws behind the seat  but not sure if it is wise to remove them when the flush tank is full!

Any ideas?

 

thanks Colin
