how can I fix my little yello steam cleaner?

Hello there, i've had a little yello for about 7mths and I luv it. But I used it in the evening & it worked perfectly, the next morning I tried to use it again but it won't heat up at all. Usually when first switched on 2 lights will come on, a red power light and an orange light that goes off once the steamer is ready. However now just the red power light comes on, and I wonder is there anything I could try to fix it myself?
Kindest regards
