Why nobody reads product manuals, and why that’s not the customer’s fault

Before you buy it, the manufacturer is remarkably good at answering questions. There’s a table explaining why one model costs €400 and another costs €900, a video of the milk system in action, and enough close-ups of the grinder to make you feel unusually well informed about grinders. A few days later, a €700 machine is on your kitchen counter. The 96-page manual is somewhere under the cardboard. You set it aside and get on with making coffee.

Twenty minutes later, a little orange light starts blinking. You dig out the manual, go past the safety warnings and find a drawing of a machine that looks almost like yours. The meaning of the light depends on how fast it flashes, so now you’re standing in your kitchen trying to decide what the manufacturer considers a fast blink. Eventually, a stranger on YouTube with a terrible microphone shows you in 40 seconds.

The work starts after you open the manual

You did read the manual, or at least the part you could find. You also spent several evenings reading about a purchase you hadn’t made yet. The manufacturer made that research easy. Once the machine was yours, answering one small question meant matching a diagram to an appliance and a sentence to the behaviour of an LED.

The paper is easy to blame. Put a QR code on the machine, though, and you can end up pinching and zooming through the same 96 pages on your phone. A PDF can be a perfectly good reference, especially if you want to save a copy. The code could also take you straight to the help page for your model, where a short clip shows you what each blink looks like. The distinction matters quite a bit when you’re trying to tell two flashes apart.

Six months later, you’re looking under the machine

By now, making coffee is the one thing in the kitchen you can do half awake. Then the descale light comes on. You need to know how to start the cycle and whether to take the filter out first. You could probably do with a new filter anyway, so you open the manufacturer’s shop and find several that look like the one you have. The model number is on the underside of the machine. Finding it would have been a more pleasant job before you filled the water tank.

Two years in, a plastic connector in the milk system breaks. The machine still makes good espresso. In the spare-parts catalogue, the connector seems to come with one of several nearly identical milk containers. Support asks for a photo and a serial number, which may genuinely be necessary if the part changed during production. A few days later, someone else asks you to describe the problem again. You can see how a machine that’s perfectly capable of making another thousand coffees might end up being replaced over a piece of plastic.

The parts catalogue may be doing exactly what it was built to do. The same goes for the warranty system and the tool the support team uses. Each has a reason to exist and probably an entirely sensible way of identifying the machine. Somehow, the person with the broken connector is the one who has to make them agree.

What the number on the underside could do

Manufacturers already use model, batch and serial numbers to keep track of what they make. A code on the machine could put some of that information to work in the kitchen. Scan it and see the instructions and filters for your model. If a replacement part depends on the production run, use the serial number to narrow it down. The same product page could take you to warranty registration or an authorised repairer. If you contact support, you could choose to share the machine’s details with them. All of that can start with a label. The coffee machine can stay happily oblivious to the internet.

The EU’s Digital Product Passport gives this idea a practical starting point. It provides a way to link a physical product to structured information, with requirements that vary by product group. A passport can point to information about the product. A useful repair or warranty service still depends on what the manufacturer builds around it.

That’s one of the problems we’re working on at Afterlayer. We start with the identity of the product because the same machine turns up in the manual, the warranty records and the parts catalogue. Making that connection takes more work than printing a QR code. Someone still has to keep the parts list accurate, make the parts available and give support a way to pick up where the last conversation left off.

Back to the orange light

I’d keep the manual. Detailed safety and maintenance instructions deserve a place you can go back to. For the orange light, I’d take a ten-second clip of the right machine blinking. For the broken connector, I’d take a photo and a part number. An AI assistant could probably explain what descaling is while I’m looking for the filter. I’d still like to know which one fits.

The next time you shop for a coffee machine, you may have forgotten which model had the better grinder on paper. You’ll probably remember whether the company could tell you which little plastic part you needed.
