hi. i went out to a hotpoint fdfex11011x dishwasher flashing f05 error. it actually completed a cycle ok for me so i have not seen the fault. The customer has reported they used it after i left and it flashed the F05 error at the start of the wash. when they opened the door there was no water inside and the detergent flap was still closed.. at first i thought it may have been a draining error code. can anyone point me in he right direction with this error code please. thank you
mark.
