Re: Hotpoint Dishwasher Model DF42 Error Code
These dishwashers are a facelifted version of the 7882/7883/7885 series produced over 12 years ago, it is possible that FIA may just be a corrupted display that could actually be E1 plus another random figure. The only fault codes listed in the manual are E10.E11.E21 & E22.
There are 5 service programmes used for running diagnostics checks but that is best left to a qualified engineer, failure to observe the correct procedure can result in overfilling etc.
NB. E10 is a fill time out ( it has not filled or emptied ) within five minutes
E11 is a heater time out fault ( it has not reached the required temp in 45 mins)
