Fisher and Paykel Excellence 7.5 Smart Drive problem?

I have an older model Fisher and Paykel Excellence washing machine. Yesterday I was washing and it when out of balance. I sitched it off by the wall and left it off overnight. All the lights come on when I switched in back on. I powered it on and advanced it to spin mode to pump the water out but it starts then stops and tries to pump out about 8-10 times and stops, then I get the spin, short wash and 5th lights come on and beeps. How do I fix it? If I cant fix it is it worth being repaired or should I buy a new one?
