hoover optima wont switch to a max spin and now holds water on a quick wash?

my optima oph616, has started to stop when on a quick wash and holds water inside, it also struggles to select a max spin. I have to twist the dial backwards and forwards from no spin to max spin a couple of times before the lights flash into the correct place. can you help I have 5 days left before ive had it one year
