Yes the DV. It's on the right, back a bit. Microswitch(es) on top should get pressed (upwards) when you turn the hot water tap on. Probably just the diaphragm, which is in the big end. You can get just the bits from that end for a few quid. You need something like a mini right angled ratchet screwdriver on all 8 screws to change it.
