You probably have problem with oxidised contacts on stb temp probe, and for dev and bleach, it could be burn out heaters or if there is circulation error then it is normal that heaters are off, or there is a problem with Triacs BT12 on the tank board, or something else on the tank board ?

Maybe main fuse is blown ?
