Hi People, I have a Vitra concealed flush, Probably 10 years old. It was dribbling into pan until I took the flush panel off and removed the back box. Now water appears be bypassing the tank and going straight down the pan. I have taken photos, 1 with a piece of metal holding the lever up, and one without. You can also see that to the left of the orange thing there is evidence of leaking. Google lens has not been any help, not can I find any help on Vitra's website. Access looks very tight anyway. Any suggestions?
