circuit diagram for dishlex 100 thermostat connections?

While replacing the heater element in my dishlex 100 ,three connections on the thermostat were dislodged. they were :1) a connector with two light blue wires
:2) a connector with a single light blue wire
:3 a connector with a single orange wire.
I replaced the connectors as they appeared to have come off but the timer does not advance beyond the first step ie.the pump works but heating does not commence.
It seems the thermo connections are not correct.
