Hi just read your posting.Now the error code you have indicated is Error code 48--49 , This error code is for hot or cold water valve fault.Now you say you just bought the machine.Did you buy it new or second hand?My manual says that the causes of this fault are due to 1---Faulty valve coils 2---- Faulty wiring or 3--- Faulty motor controller.If you bought this machine new then it would be wise to ring the place where you bought it from and ask for warranty.If you bought it second hand then please reply and I can guide you throe the finding of the exact fault and repair.Good luck.
