I purchased a new Hotpoint WD640 washer dryer last weekend but following first use the digital display shows F-03. I cant find what this code means in the instruction manual or the hotpoint website.
It could be a fault caused in transit if this is the first time you have used it.
F03 is supposed to indicate an NTC fault. You need to contact Hotpoint service to attend to this machine. It has Indesit electronics in it which are prone to all sorts of faults, some which don’t even match the error codes.
