When a product no longer works, the customer wants to know if they can repair it, if they must exchange it, or if it is covered by the warranty. A wrong answer can waste time or worsen the breakdown.
The chatbot must qualify the situation before transferring to after-sales service. It can ask the right questions, suggest simple and safe verifications, collect useful evidence, and stop guiding as soon as a risk appears.
This guide explains how to use an AI chatbot to prepare a breakdown diagnosis without replacing a technician.
Summary
Why diagnose without jumping to conclusions too quickly?
A symptom can have several causes: an empty battery, a bad connection, an incompatible accessory, normal wear and tear, a manufacturing defect, or accidental damage. The chatbot must not make a decision too quickly.
Its role is to structure information to speed up the after-sales service. It helps to distinguish between simple checks and situations that require expertise.
A good chatbot diagnosis prepares the right decision, but does not replace the after-sales service decision.

What information should be requested?
The bot must request the product reference, the order, the purchase date, the symptom, the time of onset, any error messages, the accessories used, any troubleshooting steps already attempted, and helpful photos or videos.
It must also ask if the problem presents a risk: heat, odor, abnormal noise, smoke, leakage, breakage, electrical hazard, or danger to a person.
What verifications should be proposed?
The chatbot can suggest simple and safe checks: restarting, charging, checking the connection, cleaning a designated area, removing an accessory, checking for an update, or looking up a known error.
It must not advise opening the product, forcing a part, bypassing a safety feature, or using an unintended tool.
How do I handle the warranty?
The bot can check the warranty period, order, type of problem, and general exclusions. However, it must avoid announcing definitive coverage before the file is analyzed.
It can say: "Your purchase appears to still be within the warranty period, but the after-sales service team will need to verify the cause of the problem."
When to stop testing?
The chatbot must immediately stop testing if the customer reports a safety hazard, a hot product, an odor, a leak, an alarming noise, a broken component, or a dangerous manipulation.
In these cases, the correct response is to advise stopping use and to transfer with urgency, according to the brand's guidelines.
Which flow to follow?
The flow must qualify the failure without taking any risks.
Identify product, order, purchase date, symptom, and context of occurrence.
Check safety risks before any manipulation.
Offer only simple, documented, and reversible checks.
Collect photos, videos, error messages, and tests already performed.
Transfer persistent failures, warranties, risks, damages, and uncertain diagnoses.
Which messages should be used?
To frame: "First, I will qualify the symptom and check that no risky manipulation is necessary."
To limit: "I do not advise you to open the product or force any part."
To transfer: "Since the problem persists after simple checks, I am forwarding it to after-sales service with the tests already carried out."
When to transfer?
The transfer is necessary if the product remains broken, if the warranty applies, if a risk arises, if the customer requests a replacement, if the diagnosis is uncertain, or if a part appears defective.
The bot must transmit the product, order, symptom, date, warranty, tests performed, photos, videos, error message, and urgency level.
Which KPIs should be monitored?
Track started diagnostics, frequent symptoms, successful tests, after-sales service transfers, open warranties, safety risks, and resolutions without product return.
This data helps improve instructions, product quality, and after-sales service responses.
Which mistakes should be avoided?
Avoid jumping to the conclusion of a permanent breakdown too quickly, advising an unplanned procedure, refusing a warranty without analysis, or ignoring a safety signal.
The chatbot should shorten the path to the right after-sales service, not play the role of an improvised technician.
How can Qstomy help?
Qstomy can connect the chatbot to the catalog, product sheets, variations, proof of compliance, orders, and customer service rules to respond clearly, and then transfer sensitive cases with an actionable summary.
The chatbot helps the customer move forward without inventing compatibility, certification, configuration, or a diagnosis that still needs to be confirmed by a reliable source.

The Chatbot's Proper Limit
The chatbot can guide safe checks, but it must transfer persistent breakdowns, guarantees, risks, and uncertain diagnoses.
