In a tight commercial kitchen, the ice machine usually ends up wherever there is a spare 600mm of wall — and that spare 600mm is almost always beside the dishwasher. It is a decision made quickly on a busy fit-out day, and it is one that quietly costs venues production, ice quality and cleaning hours for years afterwards. The good news is that the conflict between these two appliances is entirely predictable, which means it can be designed out rather than lived with.
Why Ice Makers and Dishwashers Make Difficult Neighbours
On paper, an ice machine and a dishwasher look like natural companions. Both are stainless, both are plumbed, and both like to sit against a wall in the wash-up corner. In reality they pull in opposite directions. An ice machine is a refrigeration unit manufacturing a food-contact product, while a dishwasher is a heat-and-steam appliance that also throws detergent, rinse aid and food debris into the surrounding air. Sit them side by side on the same bench run and each one makes the other work harder.
Heat rejection meets steam
An air-cooled ice maker removes heat from the water and dumps it straight back into the room. A dishwasher does something similar with steam, and a pass-through or door-type machine releases a plume every time the door lifts. In a corner where the two share the same pocket of air, the ice machine ends up drawing in warm, humid air for most of service. The result is longer cycles, less ice produced during the busiest interval, wetter cubes and clumping in the bin. Published output figures assume particular ambient and water conditions — the catalogue deliberately separates ice format, model-specific production conditions and usable bin capacity for exactly this reason. A machine breathing dishwasher steam will rarely match its sticker.
Moisture, detergent and the ice you serve
Steam condenses on the coldest surfaces it can find, which means the ice machine’s louvres, bin lid and door seals. Add kitchen grease to that moisture and you get a film across the condenser fins that quietly strips efficiency and turns routine cleaning into a scrubbing job. Then there is chemistry: detergent and rinse aid aerosols, splash from an open door as a rack comes out, and spray from the wash-down hose at close-down. Ice is served in drinks and buckets with no rinse cycle in between, so separation from the wash-up is a food safety issue, not just an efficiency one.
The human conflict is just as real. If the only path from the pass to the wash-up runs past an open ice bin, staff will be carrying scraped plates over exposed ice at peak. Dishwasher doors drop down, ice machine lids lift or slide, and racks need stacking space — plan the swings so they do not collide.
Layout Rules That Prevent the Conflict Before Installation
The most effective fix is to stop treating the ice machine as whitegoods and start treating it as food production equipment. Where the footprint allows, give it its own zone with a run of bench, a doorway or a wall between it and the dishwasher. Failing that, the goal is to break the shared air pocket rather than simply squeeze both units into the same gap.
When they genuinely have to sit side by side
Small sites often have no choice. In that case, fit a solid stainless divider or splashback between the two so the dishwasher’s steam side and the ice machine’s intake are not facing each other, and orient the bin door away from the door that opens during service. Do not stack dirty dish racks against the ice machine’s louvres. Leave the clearances stated in the manufacturer’s installation manual — not the minimum that lets the unit slide in — and consider dedicated extraction over the wash-up so the plume is pulled away rather than left to drift. Locating the ice machine on the cooler side of the room, away from ovens and fryers as well, buys back production capacity on hot days.
Split the system instead of the corner
Modular ice makers paired with a separate storage bin are a genuinely useful answer to a cramped layout: the ice-making head can sit where there is airflow and service access, while the bin sits wherever staff actually need ice. Self-contained under-bench units are simpler and cheaper to place, but the whole unit lives with the heat. A front-of-house ice and water dispenser can also remove drinks service from the wash-up corner entirely.
Services deserve their own line on the plan. The ice machine needs a potable water supply, ideally filtered, and its own drain with an air gap — not a shared connection with the dishwasher’s discharge, which is hot, greasy and chemical-laden and a genuine backflow risk. Confirm dedicated power and clear access to the front panel for condenser cleaning, or the machine will be serviced from a ladder over a sink.
Matching the Machine to the Corner You Actually Have
Consider a café with a two-metre back wall: an under-bench dishwasher at one end and an under-bench ice maker at the other puts both heat sources under the same bench void. Sizing the ice maker to the busiest hour rather than the whole day, and moving drinks ice to a countertop dispenser out the front, often solves the problem without rebuilding the back of house. Compact countertop nugget dispensers suit small footprints, while higher-capacity units cover venues that go through ice quickly at lunch.
Pubs and hotels have a different pattern, because glass washers at the bar produce their own steam and the main wash-up sits out the back. Keeping ice close to the bar and using modular heads with remote bins protects production, and gourmet or cube formats can be matched to the drinks list — a Scotsman gourmet ice maker for premium service, or a Skope SPIKA half dice or full dice cube maker where a consistent cube matters. Bakehouses face the reverse problem: the room is already hot from ovens, so an ice machine placed beside a dishwasher in the same corner may need extraction before anything else.
The range itself gives you room to trade off. The Atlantic Equipment ice machine catalogue currently lists 228 products — a live count that can change — across self-contained, modular and countertop formats, including Scotsman, Skope, Hoshizaki, Blizzard, Bromic and Polar lines, plus water filters and bins that make the split system workable. Because the same Granville showroom also covers dishwashers and refrigeration, it is possible to compare the two appliances you are about to place together rather than choosing them from separate brochures. SilverChef Rent-Try-Buy is available as an authorised dealer arrangement for venues testing a layout before committing, and advice, delivery, installation and after-sales support are worth using early — a five-minute conversation about the steam side of your dishwasher is far cheaper than relocating a plumbed machine later.
