EE22 means it has failed to light 3 times in a row. You can reset it by unplugging it for about 30 mins. You should find out why it isn't lighting first because if it keeps going thru the start up sequence you will get a lot of unburnt kerosene in the burner which could be a hazard. Your igniter could possibly be bad or it may not be getting any fuel so that it doesn't light.
