The bracket into which my mira showerhead slots rotates in a circular direction (clockwise and anticlockwise), but this morning it stopped rotating up and down, becoming stuck in the most upwards position. The result is that the water shoots over my head and hits the wall rather than me! I have tried for quite a while to fix it, but it seems locked. Yhanks for any advice.

Does your shower head look like this one ? How old is it ? Back to you. Milo
