Re: Miele G7859
“F2E – When water intake has not been completed within the overriding time control of 5 mins, the program is interrupted”
If the hot supply is intermittent this can knock the machine out – use a y-piece and put hot and cold hoses off the cold supply only. Normally though, if you get an F1E, F2E or F3E and the water supply is OK and filters are clean, I normally change out the heating level control switch – part nr 4441514.
