'Yes' I can confirm that the grill element can be changed without pulling this built in cooker out from its cupboard. Withdraw supply fuse.
Two screws holding the element at the back of the top oven must be removed plus two screws at the front of the oven that hold the support shelf in position.
Pull the complete element out about two inches and the connection terminals will be exposed. Disconnect four attached wires plus an earth lead. Discard the old element and reconnect the new. Feed the assembly back into correct position and secure with two screws. Finally, refit the front support shelf and supply fuse. (It took Whirlpool 4 months to supply part at £98.49)
