fisher & pykal washing machine 4 years old?

code 49 comes up , i have an extention hose that i
use for grey water , one day i went out and mowed
the lawn and left the hose hanging up on a tree ,
it sat there for three days while my wife did the washing , thats when the fault appeared, is there any thing i could do to be reset it , the soliniods arent allowing the water to come through , how could this have happen if the water pump is restricted, thanks Tony.
