I've watched a perfectly good Saturday night fall apart at 9.27pm because a glasswasher couldn't keep up. Not a power cut. Not a bar shortage. Just a wash-up that ran out of clean glassware twenty minutes before the second half. Paper cups by 9.45. Apologetic pints. A queue that gave up and walked. (I'm Andrew Pickersgill, MD at eCatering - and if there is one bit of kit operators undersize for the World Cup, it's this one.)
Wash-up doesn't sell pints. Until it does. Get it wrong on a 600-cover sport night and you're losing revenue on every pour after half-time.
Here's the playbook.
────────────────────────────────────────
Why outdoor bars need a different wash-up strategy
Indoor bars route everything to a fixed wash-up at the back. Glasses go on the pass, somebody runs them down, fifty seconds later they're back on the shelf. Tidy.
Outdoor bars don't get that luxury.
If your beer garden bar is twenty metres from the back-of-house wash-up, you're either walking glasses through a packed crowd, or you've got a glass collector running fifty-metre laps every five minutes. By half-time he's exhausted, the trays are stacked four high, and the pint glass shelf above the pour is empty.
Volume on a sport night is brutal. The pillar lays out a 600-cover scenario where the bar shifts roughly 2,900 glasses across the night. Even at a 60% return rate (the rest go to tables, gardens, get lost or pocketed), that's 1,750+ glasses through the wash. Across a five-hour trade window. With a half-time crunch where 600 of those land in a fifteen-minute spike.
Three things bite outdoor wash-up that you don't think about indoors:
-
Water and waste. Mains feed and a drain run aren't always near where you want the bar.
-
Power. Single-phase 13A is fine for a small glasswasher; a paired wash needs a 32A spur. Generator power is a problem. (More on that later.)
-
Weather. Rain on a hot machine cracks glass. Cold ambient air lengthens cycle time. A canopy isn't optional.
Get any of those wrong and you're back to paper cups before the second half whistle. Lost revenue all night.
Glasswasher vs dishwasher - what's the actual difference?
People use the words interchangeably. They aren't the same machine.
A glasswasher has a smaller basket - typically 350mm or 400mm square. Cycles run gentler and shorter (60 to 120 seconds). Wash and rinse temperatures are lower, which protects glassware from thermal shock. The whole machine is built around glass.
A dishwasher runs a bigger 500mm basket. Cycles are longer (90 to 180 seconds), with more aggressive jets and an 82°C+ rinse for hygiene. It's built for plates, pans, mixed crockery - anything where you need heat to shift fat and food residue.
Why does it matter for an outdoor bar? Because you need both formats.
The glasswasher handles pint, half-pint, wine and cocktail glasses. Volume work. Quick turn. The dishwasher handles pint pots (which jam most glasswasher baskets - the handle catches the rack), service trays, food plating from the kitchen if your bar's also doing match-day food. One machine can't do the job of both. Try it and you'll be unloading broken glassware at 10pm.
What to look for in a glasswasher for outdoor use
Five things actually matter. Don't get distracted by the rest.
Basket size
-
350mm - compact, slow throughput. Fine for a back bar under 100 covers. Not enough for a sport night.
-
400mm - the workhorse for medium-to-high volume bars. Roughly 30 glasses per basket depending on rack and glass shape.
-
500mm - full-size. Doubles as a dishwasher. Best paired with a 400mm rather than used alone for glassware.
Cycle time
Budget machines run 90 to 120-second cycles. Premium units offer 60-second express programmes for peak service.
The number that actually matters isn't cycles per hour. It's glasses per hour. A 400mm unit on a 120-second cycle does roughly 30 baskets/hour, which works out to around 900 glasses/hour theoretical. Real-world, with loading time, varied glass shapes and an inevitable half-time stack, you're looking at 80% of that. So call it 720 actual.
Hold that number. We'll come back to it.
Power supply
Most commercial glasswashers run on standard single-phase - either a 13A plug-and-play unit (small ones) or a 32A hardwired spur (anything 400mm+). Three-phase is rare for glasswashers. It's more common with paired dishwasher installs, especially the larger pass-through models.
Outdoor bars: confirm a weatherproof socket and a separate spur if you're running off the cellar circuit. Don't share with the bottle coolers. If somebody trips a circuit, you don't want the wash going down with it.
Drain pump vs gravity drain
A gravity drain is simpler - but it needs a floor drain physically below the unit. Easy in a fixed indoor bar. A nightmare in a temporary outdoor setup.
A drain pump lifts wastewater up to about 1.5 metres, which means you can plumb into a sink waste, an internal drain through a wall, or a remote gulley. For outdoor or temporary bars, a drain pump is non-negotiable.
Detergent and rinse aid pumps
Built-in chemical pumps deliver consistent dosing every cycle. That sounds boring until you've been on the bar at 9pm Friday with manual dosing and watched a tray of streaked glasses come out because somebody forgot the rinse aid bottle ran dry.
Auto-dose isn't a luxury. At volume, it's hygiene-critical.
The Contender glasswasher range - our outdoor heroes
This is what we'd put behind a serious sport-night bar. Both machines are workhorses we sell daily into UK pubs and hotels.
Contender PRO 400mm Glasswasher (DMG010)
The standard pub glasswasher in the UK. There's a reason it sells.
-
400mm basket
-
Drain pump included
-
Roughly 120-second cycle
-
~30 glasses per basket - about 900 glasses/hour theoretical, 720 actual
-
Single-phase 32A
-
Detergent and rinse aid pumps fitted as standard
-
Around £950 ex VAT
If you've got one bar and you're asking which single machine to buy, this is it. It's the formation's central midfielder. Reliable, gets through everything, doesn't make a fuss.
Contender PRO500 Dishwasher/Glasswasher
The bigger sibling. Doubles up.
-
500mm basket
-
Three cycle options - 90, 120 and 180 seconds
-
Up to 500 plates/hour on the dishwasher cycle
-
Handles pint pots, large glassware, service trays, food plating
-
Detergent and rinse aid pumps included
-
Around £1,400-£1,500 ex VAT
Pair it with the 400mm glasswasher and you've got the full wash-up formation. One does volume glassware, one handles everything that doesn't fit. Browse the full Contender range for the rest of the line-up.
A note on budget. We do a Quattro range for operators who need an entry point - solid kit, smaller capacity, fine for a back-bar or a low-volume venue. For a sport-night outdoor bar, though, the Contender's the right call. The Quattro will run, but you'll be at the edge of its capacity by half-time.
How many washers do I need? (The 600-cover formation)
Right. Maths.
The pillar piece runs a 600-cover scenario across a five-hour World Cup trade window:
-
2,900 glasses total across the night
-
1,750+ through the wash at a 60% return rate
Now layer the wash-up capacity on top:
-
A single PRO 400mm at 720 actual glasses/hour × 5 hours = 3,600 glasses across the night
-
That looks fine on paper. It isn't.
Here's why. The flow isn't even. Half-time hits at the 45-minute mark and 600 glasses come back in fifteen minutes. That's a rate of 2,400 glasses/hour for that quarter-hour. No 400mm glasswasher in the world does that solo.
You need parallel capacity.
Realistic minimum for a 600-cover sport night:
-
1× Contender PRO 400mm glasswasher (the volume work)
-
1× Contender PRO500 dishwasher/glasswasher (pint pots and overflow)
-
Combined ex VAT: roughly £2,350 - £2,450
For multi-bar venues - separate beer garden bar, separate marquee bar - give each its own dedicated PRO 400mm. The whole point of an outdoor bar is to keep the trade close to the pour. Walking glasses fifty metres to the indoor wash defeats the purpose.

Outdoor wash-up: where it sits
You've bought the kit. Now place it.
-
Within 5 metres of the pour. Closer is better. Faster glass turn means fewer glasses lost in transit.
-
Under cover. A canopy, gazebo, or hard roof. Rain on a hot machine cracks glass and rusts the casing.
-
Minimum 100mm rear ventilation. These machines vent heat and steam. Don't push them flush against a wall.
-
Plumbed to mains water and a drain pump waste line. Mains pressure should be 2-4 bar. Below 2 and your rinse won't work properly.
-
Single-phase 32A spur, weatherproof. Or 13A if you're on a smaller unit.
-
50mm waste pipe to the nearest internal drain. Don't run waste into a soakaway or a gulley that backs up in heavy rain.
Get the install right and you'll forget the wash-up exists. Get it wrong and it'll be the only thing you think about for ninety minutes.
What goes wrong with outdoor wash-up
Seven failure modes, in order of how often we see them.
-
Wrong cycle for the glass type. Pint glasses crack on a 60-second budget express cycle. Use the standard wash for thicker glassware.
-
No detergent dose. Manual dosing system runs dry mid-service. Glasses come out streaked and the EHO notices.
-
Limescale build-up in hard water areas. No water softener, no descaler programme - six months in, rinse jets clog and the machine's down.
-
Drain pump fails. Water backs up, the cycle stops, and now you've got a wet floor and a queue. Always carry a spare pump.
-
Rinse aid empty. Glasses don't drain or sheet properly. They come out of the cycle still wet.
-
Wrong rack for the glass shape. Loaded glasses tip mid-cycle, break, and now you're picking shards out of the rinse arm.
-
Power surge from generator-fed bars. This one's the killer. Generators throw voltage spikes that fry the electronic control board. If you must run off a generator, fit a voltage stabiliser.
Notice anything? Five of those seven are about consumables and chemistry. Which is why the next bit matters more than people think.
Cleaning chemistry: where KINN fits
The machine is half the wash. The other half is what goes in it.
KINN is our premium eco-friendly cleaning and hygiene range - glasswasher detergents, rinse aids, descalers, surface sanitisers, the chemistry that keeps the wash-up running clean. Eco-formulated, biodegradable, lower phosphate content than the standard commercial chemistry. (Which matters more every year as water authority scrutiny tightens.)
It pairs naturally with the Contender wash-up. The detergent's calibrated for commercial cycle temperatures. The rinse aid sheets properly off pint glassware so they come out the rack clear, not streaked. And the descaler programme keeps the heating elements clean in hard water postcodes - most of the south-east, much of the midlands, parts of Yorkshire.
You don't have to use it. But if you're spending £2k+ on a wash-up, don't run domestic dishwasher tablets through it. They'll wreck the seals inside six months.
When to bring in a Key Account Manager
If you're doing one bar, one washer, one straight install - you don't need us on the phone. The glasswashers and dishwashers range page does the job and the team can answer questions on chat.
But if you're hitting any of these:
-
Spending £2,000+ on the wash-up alone
-
Doing a full bar refit ahead of the World Cup
-
Multi-bar venue (more than one outdoor bar, or indoor + outdoor)
-
Three-phase install needed for a paired wash system
-
Tight install window - under four weeks
…that's when Andy Whitehead, our Commercial Director, becomes useful. Andy and the Key Account team have done this in beer gardens in Brighton's North Laines, sports bars across Glasgow, beer terraces in Manchester city centre, and multi-bar venues in Edinburgh's Old Town. They size to the worst fifteen minutes, not the average - which is the whole game.
"If your wash-up gives up before the second-half whistle, you're done. Half the bar's broken before they even know it. We always size the wash-up to the worst 15 minutes - the half-time crunch - not the average. Pair a 400mm glasswasher with a 500mm dishwasher, and you've got the formation right."

Frequently Asked Questions
What's the best glasswasher for a pub?
The Contender PRO 400mm glasswasher is the standard UK choice - 120-second cycles, around 30 glasses per basket, and roughly 900 glasses/hour theoretical (720 actual at 80% efficiency). For paired use with a dishwasher, the Contender PRO500 covers pint pots and mixed kit.
Do I need a glasswasher and a dishwasher?
For a high-volume bar, yes. A glasswasher handles pint, wine and cocktail glasses on shorter, gentler cycles. A dishwasher handles pint pots, plates, and food service crockery on longer, hotter cycles. Pint pots jam most glasswasher baskets - the handle catches the rack - so you really do need the second machine.
How many glasses can a commercial glasswasher wash per hour?
A 400mm commercial glasswasher runs roughly 30 baskets per hour on a 120-second cycle. That works out at around 900 glasses/hour theoretical, or about 720 in real-world conditions at 80% efficiency. Premium 60-second cycles can push higher.
Can I use a glasswasher outside?
Yes - provided it's under cover, on single-phase mains power (not generator unless stabilised), with a drain pump and proper plumbing. A weatherproof spur, a canopy roof, and a 50mm waste run to an internal drain are essential. Rain on a hot machine cracks glassware.
How long does a commercial glasswasher cycle take?
Between 60 and 180 seconds depending on the unit and the cycle programme. Budget machines run 90-120s standard. Premium glasswashers offer 60-second express cycles for peak service. Dishwashers run 90-180s on hotter rinse temperatures.
What detergent should I use in a commercial glasswasher?
Use a commercial-grade glasswasher detergent (not domestic dishwasher tablets - they'll wreck the seals) with a separate rinse aid. KINN's eco-friendly glasswasher chemistry is biodegradable, lower-phosphate, and pairs with Contender machines. In hard water postcodes, run a descaler programme monthly.
The bottom line
Pair the wash. Pair the formats. Plan the chemistry.
A 400mm Contender glasswasher and a PRO500 dishwasher together - that's the formation. Around £2,350-£2,450 ex VAT for the pair. Sized to handle a 1,750-glass night without paper cups by 9.45pm.
If you take one number away from this piece, take 720. That's the actual glasses-per-hour you'll get from a 400mm machine in real conditions. Now compare it to your projected sport-night volume. If it's under, you need a second machine. Simple as that.
