Which tool to choose
- A visible problem (an appliance with an error code, a stain, a part you don't understand): Gemini from your smartphone. It reads the photo and connects what it sees to a likely cause.
- A problem to reason out or calculate (how to do something, a sum, organizing a procedure): ChatGPT, which explains the steps and does the math.
The interfaces change: if you can't find the photo upload, describe the problem in words, including the exact error code you read on the display. It works almost as well.
How to do it
Most household problems have a trivial cause and a two-minute solution, hidden under more serious causes. The AI's job is to make you start from the simplest one.
- Gather the details: brand and model of the object, what it does and what it should do, since when, what you've already tried.
- Ask for the simplest solution first and the safety boundaries. The working syntax:
My washing machine shows the error code E18 and doesn't drain the water. It's a [brand and model]. Tell me what that code means, the two most common causes, and what I can check on my own safely before calling a technician. Also tell me in which cases I should NOT try it myself.
- Proceed one check at a time, from the most harmless. You often stop at the first.
- If the solution touches electricity, gas or pressurized water, stop at the point where the AI flags the risk and call a professional.
A concrete example
Davide's washing machine had stopped mid-cycle with the drum full of water and an E18 code on the display. He wrote the brand, model and code to ChatGPT. The AI explained that this code usually signals a drainage problem, and that the most common and harmless cause is a clogged filter at the bottom. It told him how to drain the residual water first so as not to flood the place, and not to dismantle anything electrical. Davide cleaned the filter, finding a coin and a button. The washing machine started again. Technician avoided, fifteen minutes of work.
When it does NOT work (and how to fix it)
If it proposes a complicated solution when a simple one would do
The AI sometimes starts from the most technical diagnosis. Fix: explicitly ask for "the simplest and safest solution first", and tackle the hypotheses in order of increasing risk. In most cases the problem is trivial.
If it invents an error code or a procedure
On specific models the AI can give the wrong meaning to a code. Fix: check the official manual for your model, which you often find as a PDF on the manufacturer's site, and trust that when it contradicts the chat.
If the problem involves gas, electricity or pressurized water
Here the boundary is non-negotiable. Fix: use the AI only to understand what's happening and what to check without risk (a switch, a closed valve), but for the real work call a qualified technician. Cutting corners on this is the most expensive way to get it wrong.
A tip from someone who really uses it
Always ask for two things along with the solution: "what I must NOT do" and "why it happens". The first keeps you safe, the second means that next time you'll know how to solve it on your own, without reopening the chat. A problem understood is a problem that no longer scares you.
Frequently asked questions
Can it be done with the free version?
Yes. Describing a fault, uploading a photo and receiving a diagnosis with the steps falls within the free versions. For a few household problems you won't hit any limit.
Does a photo really help?
For objects, a lot: a code on the display, a leak, a part you don't recognize tell the AI more than a thousand words. Frame it well and with light, showing the surroundings of the fault too.
Can I trust the AI for electrical or gas repairs?
No, beyond the very trivial. It can help you understand the problem and make risk-free checks, but it doesn't replace a qualified technician and doesn't know the safety rules of your system. For anything involving electricity, gas and pressurized water, the AI's value is precisely in telling you where to stop. Knowing how to recognize that is part of the solution, not a failure.
