Case Study: Real Business, Real Results

The team at 'The Coastal Kitchen' in Whitby, North Yorkshire, were struggling with an older, unreliable dishwasher that left streaks on their glassware, requiring time-consuming polishing. They needed a dependable upgrade that could handle their busy summer season.

"Our old machine was a constant headache. Since installing the Winterhalter, our glasses are flawless straight out of the wash and  the speed is incredible. It’s given our team back valuable time and  our tables have never looked better."

Robert Finch – Proprietor

The upgrade eliminated the need for manual polishing, saving the team an estimated 45 minutes of labour per shift.

Installation and  Maintenance Guide

Setting It Up

  • Ensure the machine is installed on a firm, level surface to prevent vibration.
  • Installation, including water and  electrical connections, must be done by a qualified professional.
  • Crucially, check your incoming water pressure is at least 1.5 bar for the machine to function correctly.
  • Before its first proper use, run the built-in self-cleaning programme to flush the system.

Keeping It Going

  • Check and  clean the wash tank filters at the end of every day to remove food debris.
  • Use the self-cleaning programme regularly (ideally daily) to maintain peak hygiene and  performance.
  • In hard water areas, regular descaling is essential to prevent limescale build-up.
  • Wipe down the door seals and  the exterior with a soft, damp cloth to keep it looking its best.

Buying Guide: Choosing the Right Commercial Undercounter Dishwasher

Not sure what fits best in your space? Choosing the right machine can feel like a minefield, but focusing on a few key areas makes it much simpler. Here’s what to look for:

Capacity & Speed

Think about your busiest hour. How many racks of dishes or glasses do you need to wash? Match the machine's racks-per-hour capacity to your peak demand.

Water Pressure

This is a big one. Check your site's water pressure before you buy. Many high-performance machines, like this one, have a minimum requirement to work properly.

Running Costs

Look beyond the purchase price. An energy efficient warewasher will save you a significant amount on water and  electricity bills over its lifetime.

Drainage Position

Is your waste pipe higher than the machine's outlet? If so, you absolutely need a model with a built-in drain pump to avoid installation nightmares.

Water Softening

If you're in a hard water area, an external or integral water softener is a must. It prevents limescale, protects the machine, and  gives you a better final rinse.

Frequently Asked Questions

Q: Can this machine wash both plates and  glasses?

A: Absolutely. The VarioPower technology adjusts the pressure, making it gentle enough for delicate glassware but powerful enough for dirty plates.

A: It means the machine meets UK Water Regulations Advisory Scheme standards, ensuring it won't contaminate the mains water supply, a legal requirement for commercial premises.

A: It’s designed for commercial environments and  includes a 'Quiet Mode' to significantly reduce operating noise, making it suitable for open kitchens or bars.

Q: Does the DE646 model include a drain pump?

A: Yes, this specific model comes with a drain pump fitted as standard, offering greater flexibility during installation.

Q: Should I use a water softener with this warewasher?

A: If your business is in a hard water area, using a water softener is highly recommended to prevent limescale, protect internal components, and  ensure streak-free results.

Q: What are the electrical requirements for installation?

A: This unit requires a hardwired, single-phase electrical connection. This must be carried out by a qualified commercial electrician.

Q: How often does the self-cleaning programme need to be run?

A: For optimal hygiene and  performance, it's best practice to run the self-cleaning cycle at the end of each day's service.

How a Drain Pump Simplifies Installation

Ever wondered what a 'drain pump' actually does? It’s a simple but vital feature for many kitchens. Think of it like a little lift for your waste water. Standard dishwashers rely on gravity, meaning your drainpipe must be lower than the machine's water outlet for it to empty properly.

A drain pump actively pushes the waste water out and  upwards, giving you total flexibility on where you place your machine. If your ideal spot has a drain that's high up on the wall or further away than usual, the pump makes it possible. It removes all the guesswork and  potential plumbing headaches, ensuring your new catering undercounter warewasher can be installed quickly and  correctly, pretty much anywhere you need it.

Who Should Buy This?

  • Busy Restaurants

    Perfect for high-turnover kitchens needing a constant supply of spotless crockery and  cutlery during peak service.

  • High-Street Cafés

    Its compact undercounter design and  efficient cycles are ideal for keeping up with the breakfast and  lunch rush.

  • Pubs and  Bars

    The adjustable pressure is fantastic for switching between tough pint glasses and  delicate wine glasses without damage.

  • Boutique Hotels

    The 'Quiet Mode' is a huge plus, allowing it to be run near guest areas without causing a disturbance.
