Hi all, can anyone help please, We have just had our second trip in our beautiful brand new sterling europa 550, we were really enjoying it until 2 nights ago the toilet flushed no more! (it's electric not lever). We have checked the fuse in the outside compartment, it's ok, anyone got any idea's what could be wrong, don't want to ask dealer at this stage, they'll just ask us to take it back to them, it's quite an inconvenience, especially if it's something simple we can fix ourselves, any views gratefully received, many thanks, Dave and Lorraine.
