How can i fix my Electra Micro Deluxe 1250 Washing machine?

I have a Electra Micro Deluxe 1250 washing Machine. The other day i turned it on, and it started normally. About 5 minutes later, it stopped. There was an error message showing; F02. I restarted it, and the same thing happened. So i emptied it, checked the outflow pipe for blockages, but no luck. Removed the outflow pipe from the pump, the removed the bottle trap underneath to check to see if there was any crap in it. There wasnt. I then checked the outflow pipe from the drum to the pump, no blockage. I took the pump housing off, and the impellor was a bit stiff, so i gave it a little squirt with WD40. It seemed a bit freeer. Ihave just put it on full wash, and the same, F02 message came up. So i put it on Spin, to see if the water got pumped out, and it went for about 3 minutes, and i got a error message: F03. Now im stuck.??? Help.
