I have code f71 give me solution

Hi from retired Englishman in SW France,

Check that the washer supply is OK using another item - a kettle for instance. If it's not check your breakers/fuses. Reset/replace if necessary and if the same thing happens, or if there was nothing wrong with the breakers/fuses in the first place, sorry but with such a fault it is impossible for anybody on this forum to remotely guess what could be wrong with your washer. It could be internal wiring/plugs sockets, control panel switches, control PCB.

I fear that your only real option is a service call as the engineer will have the right equipment to safely diagnose what is wrong.

If this has assisted you please consider a 4 thumbs up for the rating.
Thanks and good luck!
