Recent job
Representative job: ECB-AP1 in a Culver City office break room, staff complaining the coffee had "gone bad" over several months. Brew temperature measured at the basket at 189 degrees against a 190-200 specification and an SCA standard starting at 195. Element scaled, tank descaled, spray head stripped and cleared, temperature re-checked at the basket across two full batches. Total: on site, under two hours, $329 flat. Nothing was replaced.
Honest opinion
Nobody chooses one of these. It arrives with the kitchen order and then sits there for a decade. That is fine — it is a competent piece of equipment for what it costs — but it means no one ever bonded with it enough to maintain it. If your Estella has never been descaled and the coffee has quietly got worse, that is not the machine reaching the end of its life. That is the first service it has ever had, still waiting.
