Indesit DI67?

Hi, i have a indesit dishwasher that has developed a fault, it smells of burning as though the water is not reaching the heating element so it is heating nothing. Cant remember if it ever covered the element before though. It will get half way through a wash and then the 2nd light will flash(wash light) and sometimes it will flash with the rinse light. Has any one had the same problem or got any ideas?
Thanks.
