e30 means the hose at the back is kinked or coiled and not letting the water out. Pull out the machine undo the kink and check the filter. Then to reset switch machine off press the last 2 buttons I think xtra rince and start hold them in turn knob to cotton wash. all the kights should flash in sinc then turn back off this should reset the fault and it should start as normal. this happend to me and i fixed it. I now have error 31 but i don'tknow what that is. Hope this works for you
