After repairing my appliances one by one, finding the schematics, diagnosing parts and then searching for replacements I discovered the cheapest model and the most expensive model of most appliances by the same manufacturer share all the same parts except the exterior and control panel.
That dishwasher or washing machine with extra modes for $1,000 more? It's the same as the cheapest model, they just didn't put the extra controls on the panel.
