| 01 | Intake On the phone | Make, appliance, whether it is built-in or freestanding, the symptom in your words, how long it has been happening and what changed in the house around it. | Whether a visit is the right answer at all, and which parts are worth putting in the van before we set off. |
| 02 | Access Before anything is dismantled | How the appliance is fitted: the opening it sits in, the grille or toe-kick it breathes through, what has to come off to reach the back, and whether it rides on rails or has to be lifted. | What the job will actually cost in time, and whether the fault is the installation rather than the appliance. |
| 03 | Reproduce In your kitchen | The fault is made to happen under the conditions it fails in — a full cycle, a loaded pan, a door closed for an hour — rather than described from memory. | Intermittent against constant. A fault that will not reproduce is a different investigation from one that will. |
| 04 | Measure At the component | Electrical and thermal readings taken where the part lives: continuity and resistance, voltage under load rather than at rest, temperatures across the cavity or the coil, pressure and flow at the supply. | Which component is out of specification, as a number written down, rather than which one is easiest to sell. |
| 05 | Parts Against the serial number | The component identified against the model and serial, not the model alone, then checked for whether it is still current and what the lead time is. | Whether the repair can be finished at all. On older built-ins this is the question that decides everything after it. |
| 06 | Estimate Before any work | A written figure, itemised part by part with the labor against it, handed over before anything is fitted — including the case for not repairing it. | What you owe, and whether the appliance has a future worth spending it on. |
| 07 | Verify Before we leave | The appliance reassembled, levelled, resealed and run through a full cycle, with the readings from stage four taken again to confirm they moved. | That the original symptom is gone rather than merely quiet. The warranty starts from the date on that invoice. |
