how can i fix my hotpoint?

There's a man in New Zealand who will tell you exactly what to do - but he's probably in bed just now...

H2O is the chemical formula for water - your machine might be complaining of too much of it or more probably not enough.

Very often on washing machines the water inlet valve fails - your problem could be this.
