Guides

Buying guides in this category tend to stop at the purchase. That is a strange place to stop, because most of what makes owning one of these machines good or bad happens afterwards: whether the ice keeps (it does not), what the electricity actually costs (less than people think), and whether you clean it (mostly not).

So these guides are organized around the questions people ask after they have started living with the appliance, plus the few before it that genuinely change which one you buy.

Three groups

Why the running-cost guide exists

Because nothing in this category publishes one. Not one roundup we examined while researching this site reports cost-to-run, wattage or kWh for any model, and the handful of pages that do cover it are single-model, years old, and built on a wattage figure with no stated source.

The version here computes a monthly figure for every machine we could source an electrical rating for, states whether that rating is a published consumption figure or a nameplate ceiling, cites the manual page it came from, names the duty cycle assumed, cites the EIA for the electricity rate, and lets you substitute your own numbers. That is a low bar and it is not currently cleared by anybody else.

And why the maintenance guides are cross-brand

The cleaning advice that exists for these machines is brand-specific: GE's support pages cover the Opal, and if you own something else you are on your own. Meanwhile the machines with the least documentation are the ones whose owners most need a written procedure.

The cleaning guide here is assembled from every manufacturer manual we could read, with the brand differences called out where they differ. It also draws the distinction almost nobody draws, which is worth stating twice: cleaning removes biofilm and needs detergent, descaling dissolves mineral scale and needs an acid, and doing one does not do the other.

What you will not find here

• Impressions of how any machine performs. We have not used them.
• Decibel figures. Nobody publishes them and we are not repeating other people's.
• A lifespan number. Nobody publishes that either.
• Health advice. The page on ice and teeth exists and is deliberate about where it stops.
• A product recommendation on every page. Some of these guides carry none, and each of those says why.
