how can i fix my washing machine indesit wg1130t?

Indication of a fault within the machine - i'd start with the heater.
check the heater and thermostat connections and the connections on the timer, (looking for a burnt out terminal or wire). The machine would have stopped in heat pause, and is waiting for the water to reach the correct temperature before advancing on.
