Many service manuals are available free online. I recently diagnosed and repaired my very geriatric F and P smartdrive washing machine by finding the service manual and engaging in a bit of problem solving and DIY. The Service Manual is different to the User Manual that you get given when you buy a machine. The Service Manual is what the manufacturer produces for the repair technicians to use. It can take a bit of puzzling out to work out exactly what its all trying to tell you, but well worth it to save a technician call-out fee. And even if you can’t repair it yourself, you’re in a much better position to tell the tech what they need to know and save them some valuable time, too.
