Commercial Dishwashers Ireland: The Complete Buyer's Guide (2026)

If you're kitting out a restaurant, café, bar or hotel kitchen in Ireland, a commercial dishwasher is one of those purchases that quietly makes or breaks your service. Get the wrong one and you'll be bottlenecked at the pass every Saturday night. Get the right one and nobody in the kitchen ever thinks about it again, which is exactly how it should be. This guide walks through the main types of commercial dishwashers available in Ireland, what actually matters when picking one, and roughly what you should expect to pay.

Why the Right Commercial Dishwasher Matters

A domestic dishwasher simply won't survive a busy commercial kitchen. Commercial machines are built to hit HACCP-compliant rinse temperatures, run cycles in as little as 90 seconds rather than an hour, and keep going for service after service, year after year. Picking the wrong size or type for your volume is one of the most common (and costly) mistakes new operators make: too small and you'll have a bottleneck at peak times, too large and you're wasting water, power and floor space you didn't need to give up.

The good news is that once you know your throughput needs, matching yourself to the right machine is straightforward. There are five main categories worth knowing.

Types of Commercial Dishwasher

1. Undercounter Dishwashers

Undercounter (frontloading) dishwashers are the standard choice for cafés, small restaurants, bars and takeaways. They sit under a worktop, run a 500x500mm basket, and typically wash a cycle in 90 to 120 seconds.

The Combisteel SL Dishwasher Frontloader 500-230 is a solid entry point — a compact single-phase machine with a 20-litre wash tank that handles plates, glasses and cutlery together, ideal for a smaller café or bar setup. Step up to the Combisteel PL Dishwasher Frontloader 5035 E and you get a Pro Line model with a larger 35-litre tank, digital controls and a built-in detergent dispenser — better suited to a busier independent restaurant.

• ✅ Best for: cafés, bars, small restaurants, takeaways
• ✅ Typical throughput: 30–40 baskets per hour
• ✅ Footprint: fits under a standard worktop

2. Pass-Through Dishwashers

Once you're doing serious covers — a busy restaurant, hotel, or contract catering kitchen — a pass-through (hood-type) dishwasher is usually the better fit. Baskets load in one side and come out the other, with a hood that lifts and drops automatically to run the cycle, which speeds up service massively compared to an undercounter unit.

The Kobar K1100PT Rapid Premium Pass Through Hood Dishwasher and the Omniwash 62P/S Pass Through Dishwasher are both well suited to mid-volume kitchens, while the CombiSteel Pass-Through Dishwasher 40E pushes throughput up to 60 baskets an hour with digital cycle controls (60/120/180 seconds) and a 40-litre wash tank, making it a strong choice for a hotel or high-volume restaurant kitchen.

• ✅ Best for: busy restaurants, hotels, contract catering
• ✅ Typical throughput: 30–60+ baskets per hour depending on model
• ✅ Straight-through or corner operation to suit your layout

3. Rack Conveyor Dishwashers

For hotels, banqueting operations, hospitals and large-scale institutional catering, a rack conveyor dishwasher is the workhorse you need. Racks move continuously through the machine rather than in individual cycles, giving you sustained, high-volume throughput that no undercounter or pass-through machine can match.

The Combisteel PL Rack Conveyor Dishwasher delivers 70 to 100 baskets an hour with double-skin insulated construction for energy efficiency and reduced noise — built for operations where the washing-up genuinely never stops.

• ✅ Best for: hotels, banqueting, hospitals, large institutional kitchens
• ✅ Typical throughput: 70–100+ baskets per hour, continuous
• ✅ Three-phase power required

4. Pot Washers

No standard dishwasher will get baked-on grease off a stockpot or a roasting tray — that's what a dedicated pot washer is for. These machines use a combination of water, detergent and abrasive granules to strip heavy, stubborn soiling that would otherwise mean hours of manual scrubbing.

The CombiSteel Pot Washer 5565 PRSE is a heavy-duty digital model with a 65-litre wash tank, built-in heat recovery to keep running costs down, and four selectable cycle times to match the job at hand — a genuine labour-saver in any kitchen processing large volumes of cookware.

• ✅ Best for: any kitchen washing heavy pots, pans and trays at volume
• ✅ Cuts manual scrubbing time and labour costs significantly
• ✅ Heat recovery technology reduces energy use

5. Glasswashers

If you're running a bar, pub or busy front-of-house area, a dedicated glasswasher keeps glassware spot-free without tying up your main dishwasher. The Blizzard Storm Glasswasher STORM35 is a compact, double-skinned unit with automatic detergent and rinse aid dosing and three selectable cycle times — simple to operate and reliable behind a busy bar.

How to Choose the Right Dishwasher for Your Kitchen

A few practical questions will point you toward the right category almost immediately:

• How many covers are you doing at peak service? A café doing 40 covers a day has very different needs to a hotel restaurant doing 200.
• What's your power supply? Undercounter machines typically run on a standard single-phase supply, while pass-through and rack conveyor machines usually need three-phase power — worth checking with your electrician before you order.
• How much space do you have? Measure your gap before you buy. Undercounter units need worktop clearance above; pass-through and rack conveyor machines need a dedicated run of floor space.
• Do you need a separate pot washer or glasswasher? If your kitchen does a lot of heavy cookware, or your bar is busy enough to bottleneck a shared dishwasher, a dedicated unit pays for itself quickly in saved labour time.

If you're planning a full kitchen fit-out rather than just replacing a dishwasher, it's worth reading our guide on essential refrigeration and catering equipment for opening a restaurant in Ireland, which covers how warewashing fits into the bigger picture alongside your fridges, freezers and prep equipment.

Hygiene, Compliance and Running Costs

Under EHO and HACCP guidance, commercial dishwashers need to hit a final rinse temperature high enough to sanitise crockery and utensils, not just clean them visually. That's why most commercial machines built for the Irish market include a dedicated rinse boiler separate from the main wash tank, running at a higher temperature for the final rinse cycle. This is one of the biggest practical differences between a domestic dishwasher and a proper commercial unit, and it's not something you can retrofit later — it needs to be built in from the start.

Running costs are worth thinking about too. A dishwasher with a smaller wash tank and shorter cycle time will usually use less water and electricity per basket than an older or oversized unit, but it needs to be matched to your actual throughput. An undersized machine run flat out all service will cost you more in labour and water than a correctly sized one, since staff end up running extra half-full cycles just to keep up. If in doubt, it's worth erring slightly larger rather than smaller, particularly if you expect covers to grow.

A few other practical points worth planning for before your machine arrives:

• Water softening: Ireland's water hardness varies a lot by region — hard water areas can cause limescale build-up on heating elements and glassware over time, so a water softener is worth budgeting for alongside the machine itself.
• Drainage: Check whether your chosen model needs a gravity drain or a drain pump, and whether your current plumbing can accommodate it without extra work.
• Detergent and rinse aid dosing: Most commercial machines take auto-dosing detergent and rinse aid, which saves staff time versus manual dosing and gives more consistent results.

What Does a Commercial Dishwasher Cost?

Pricing varies a good deal by category and output, but as a rough guide (ex VAT, based on current ChillCooler pricing):

• Glasswashers typically start from around €1,700
• Undercounter dishwashers generally run from around €2,000 to €3,500
• Pass-through dishwashers typically range from around €3,000 to €8,000 depending on throughput and features
• Pot washers generally run from around €9,000 to €14,000
• Rack conveyor dishwashers typically start from around €14,000 and can run to €22,000 or more for fully specified high-output models

Frequently Asked Questions

What's the difference between an undercounter and a pass-through dishwasher?

An undercounter dishwasher is a self-contained unit that sits under your worktop and washes one basket per cycle, making it ideal for lower-volume kitchens. A pass-through dishwasher is a larger, hood-type machine designed for higher throughput, where baskets are loaded on one side and removed from the other once washed.

Do I need three-phase power for a commercial dishwasher?

Undercounter machines typically run on single-phase power, while most pass-through and all rack conveyor dishwashers require a three-phase supply. Always check your kitchen's electrical supply with a qualified electrician before ordering.

How long does delivery take?

Delivery times vary by model — many of our undercounter and pass-through machines ship within a few working days, while larger rack conveyor units may need a longer lead time. Exact delivery windows are listed on each product page.

What warranty comes with a commercial dishwasher?

Most of the machines in our range come with a minimum of 1 year parts and labour warranty as standard — check the individual product page for the specific terms on each model.

Do I need a dedicated glasswasher if I already have a dishwasher?

Not always, but if your bar area is busy enough that glasses are competing with plates and cutlery for wash time, a dedicated glasswasher will speed up service and protect your glassware from chipping in a mixed load.
