Hotpiont Aqualtis, Drain pump replaces...Still the same code...F-05?

I have had the same problems with mine, cleared the filter by unscrewing the small opening on the front under the panel at the bottom, i found 6 pence, but the problem is still there,
i was advised to replace the drain pump, i bought one from hotpoint £38.00 delivered, took 5 minutes to replace.
Still the same code...F-05
what can i do... other that replace the whole machine.
