Diagnose real appliance faults before you charge for them.
Interactive diagnostic labs put you on a service call and make you choose the next test — not watch someone else do it. Built for aspiring technicians getting job-ready and working independents who want fewer callbacks and cleaner first-visit fixes.
This is scenario-based practice, not another video library
Labs are branching, decision-driven, and graded on your reasoning. You get the same information a real call gives you — and nothing more — then live with the consequences of your next move.
Safety gate first
Every lab locks the diagnosis until you confirm lockout, water, and PPE steps — the same order you owe a real customer.
Branching decisions
You choose the next test. Wrong turns are allowed and explained, so the lesson sticks instead of being narrated at you.
Maya coaches you
A tutor panel sits beside every step with the reasoning a senior tech would give you over the shoulder.
Debrief that transfers
Each lab closes with the confirmed diagnosis, what you did well, what to watch for, and a model service note.
All scenarios
New labs are added every release. Start with the washer drain circuit — it teaches the test-before-you-replace habit that saves the most money in the field.
Washer Not Draining

A front-load washer fills and tumbles but finishes the cycle with standing water in the drum. Work the drain circuit in the right order.

Commercial cuber · 7 decision steps
A restaurant cuber cycles but drops no ice. Read the harvest sequence, water circuit, and thermistor data like a pro.
