How to Replace the Shroud Kit on a Gainsborough GSi 10.5 electric (UK)

Replace the concealing plate and shroud on the Gainsborough GSi 10.5 electric where limescale has locked the temperature handle.

Undo the two handle grub screws (2.5 mm hex on most Gainsborough models). Lift the shroud off — do not lever, it cracks.

Fit new O-rings between the wall plate and shroud to keep the IP54 rating.

Balance hot and cold to within 0.5 bar. Run the Gainsborough GSi 10.5 electric at max flow for 3 minutes.

Verify max outlet temperature stays below 46 °C per BS EN 1111 by shutting off cold and reading the outlet.
