Re: fault code EFO AEG 16830
not all EF codes will reset this way
there is 1 EF4 that need resetting by an engineer who can then check the machine for a fault
as a user you will get the code EF0 but if you went into the engineering mode you will get EF1, 2 ,3 or 4
EF4 Water fill pressure too low , no signal from flow meter and solenoid valve open
This machine counts the water in with a flow meter same as petrol pumps do. if this meter is not working and the timer expects it too it will lock out to prevent flooding
