Case Study: Real Business, Real Results

The Rose & Crown, a historic gastropub in York, needed to upgrade its ageing warewasher which was struggling to keep up with their busy Sunday lunch service and  leaving residue on their glassware.

"Our old machine was letting us down right when we needed it most. Since installing the Winterhalter, the difference is night and  day. The glasses are spotless, and  the speed means our team can focus on the customers, not on re-washing racks."

Robert Davies – General Manager

The pub has reduced its glassware breakage by 15% due to less handling and  has completely eliminated complaints about water marks on glasses.

Installation and  Maintenance Guide

Setting It Up

  • Ensure your site has a minimum incoming water pressure of 1.5 bar for the machine to function correctly.
  • This unit requires hardwiring to a suitable electrical supply by a qualified engineer.
  • Position the machine on a flat, level surface to ensure proper drainage and  operation.
  • Connect the detergent and  rinse aid lines to your chosen chemicals before the first use.

Keeping It Going

  • Run the built-in self-cleaning programme daily to maintain optimal hygiene and  prevent build-up.
  • Regularly remove and  clean the wash/rinse arms and  filters to ensure there are no blockages.
  • Keep the salt reservoir for the water softener topped up, especially in hard water areas.
  • Wipe down the door seals and  exterior with a soft cloth to keep the unit looking professional.

Buying Guide: Choosing the Right Undercounter Warewasher

Not sure which model fits your kitchen best? Here are a few key things to consider when choosing a professional undercounter dishwasher.

Size & Capacity

Check the external dimensions to ensure it fits under your counter, and  look at the basket size (500x500mm is standard) and  racks-per-hour to match your peak demand.

Water Hardness

If you're in a hard water area (most of the UK), a machine with a built-in water softener is essential to prevent limescale and  ensure streak-free results.

Drainage Position

If your waste pipe is higher than the machine's outlet, you'll need a model with a built-in drain pump. This one includes it, offering total flexibility.

Glassware vs. Dishes

Will you be washing mainly glasses, plates, or a mix? Look for machines with adjustable pressure or dedicated cycles, like this Winterhalter, to handle both safely.

Energy and  Water Use

An efficient machine will save you money in the long run. Look for features like precise chemical dosing and  intelligent controls to minimise running costs.

Frequently Asked Questions

Q: Can this machine wash both plates and  delicate glasses?

A: Yes, absolutely. The VarioPower technology is specifically designed to adjust the wash pressure, providing a powerful clean for dirty plates and  a gentle one for glassware.

Q: What does a 'drain pump' do?

A: A drain pump actively pushes waste water out of the machine. This is vital if your site's drainage pipe is higher than the machine's water outlet.

Q: Do I really need a water softener?

A: In most parts of the UK, yes. A built-in water softener, like the one in this model, prevents limescale from building up inside the machine and  stops white spots and  streaks appearing on your clean items.

Q: How long is a typical wash cycle?

A: Cycle times vary depending on the programme selected, but it is designed for rapid turnaround in a commercial setting, processing up to 30 racks per hour.

Q: What is a 'WRAS Approved Air Gap'?

A: It's a safety feature that creates a physical gap to prevent contaminated water from the machine from flowing back into the mains water supply, ensuring you comply with UK water regulations.

Q: How does the self-cleaning programme work?

A: At the end of service, you can activate the self-clean cycle. The machine uses a combination of heat and  water to wash its interior, ensuring it remains hygienic and  ready for the next day.

Q: What size is the rack?

A: This machine uses the industry-standard 500x500mm basket, making it easy to source and  integrate with your existing warewashing setup.

Q: Is this machine noisy to run?

A: Winterhalter models are engineered for efficiency, which includes reducing operational noise, making them suitable for installation closer to front-of-house areas.

This translates to a lower total cost of ownership over the machine's lifespan, with fewer breakdowns, reduced maintenance calls, and  consistently lower water and  energy consumption. For a busy kitchen, reliability is everything. The cost of a failed machine during peak service far outweighs the initial saving of a cheaper alternative.
