The C500WS is a good choice where the site needs a compact commercial dishwasher with a standard 500 x 500mm basket, simple staff operation and built-in water softening.

• Suitable for cafés, bars, pubs, staff kitchens, churches, village halls, small restaurants and hospitality sites.
• Useful where a standard C500 would need softened water, but there is limited space for an external softener.
• Works well where an undercounter machine is preferred over a pass-through dishwasher.
• Suitable where a 500 x 500mm basket and up to 18 plates per rack are enough for the workload.
• Useful for sites that want simple controls, built-in chemical dosing and straightforward cleaning access.

Before choosing the C500WS, the key checks are water hardness, salt-management routine, power supply, drainage, available space, incoming water services and whether the throughput is enough for peak service periods.

• Confirm whether the site is in a medium or hard water area.
• Check that staff can reliably top up salt and respond to the low salt alarm.
• Confirm the available electrical supply, 230v 13A, 230v 32A or 400v 13A.
• Check that drainage can be arranged within the manufacturer’s maximum drain height.
• Confirm whether the machine will be commissioned mainly for glasses, dishes or a mixed routine.

Where space and services allow, an external automatic softener may still be preferred for higher-use sites because it can usually go longer between salt top-ups. Where space is limited, the C500WS integrated-softener model is often the more practical solution.

The C500WS is a capable integrated-softener undercounter machine, but it will not be the best choice for every site. A different model or water-treatment setup may be better where wash volume, item size, water hardness or staff routine requires it.

• Choose the standard C500 with an external automatic softener if higher usage makes external water treatment more practical.
• Consider the C400WS if space is tight and a smaller 400 x 400mm basket is sufficient.
• Consider a pass-through dishwasher if peak wash volume is too high for an undercounter machine.
• Consider the C500 Utensil if gastronorm trays, chopping boards or larger kitchen items are a regular requirement.
• Review the machine choice if the site needs a validated medical thermal disinfection process, because the C500WS should be presented as high-temperature rinse support, not a medical disinfection machine.

The C500WS is available with three power options. The 13A plug-in version is useful where a simpler electrical connection is needed, while the higher-powered versions may be more appropriate where faster heat recovery is important.

• Power options: 230v 13A plug-in, 230v 32A single phase or 400v 13A three phase.
• Water pressure requirement: 1-10 bar.
• Incoming water temperature range: 4°C-55°C.
• Drain size: 40mm diameter, with maximum drain height of 600mm from the machine base.
• Glass cycles are listed as 1.5 and 2 minutes; dish cycles are listed as 2, 3 and 5 minutes.

Cycle performance in real use depends on programme choice, loading, incoming water temperature, water pressure and the machine’s services. The integrated softener also needs correct setup, salt management and regeneration to support consistent results.

The Classeq C500WS is the current 500 x 500mm undercounter platform with an integrated water softener. It may be relevant when replacing older Classeq 500mm integral-softener undercounter models.

For integrated-softener replacements, the most useful previous model references are D500 DUO WS and D500DUOWS. If the older machine was a non-softener model, such as D500, D500P, D500 DUO or D500DUO, the closer current equivalent is normally the standard C500, unless the site now needs an integrated softener.

When replacing an older Classeq machine, check the existing basket size, electrical supply, water treatment, drain arrangement and available opening. Classeq notes that the external dimensions of the new models differ from older models, so the site should be measured before ordering.

Previous model search terms for this product include D500 DUO WS and D500DUOWS. If replacing D500, D500P, D500 DUO or D500DUO, consider the standard C500, or review whether the C500WS is now better because integrated water softening is required.

The C500WS supports hygienic commercial dishwashing through correct temperature, detergent, rinse aid, water quality and staff routine. It should not be described as a medical disinfection machine.

• The dish rinse temperature is listed at 82°C.
• The machine incorporates a Type AB WRAS Approved air gap.
• The integrated softener helps manage limescale risk where salt is maintained correctly.
• Built-in hygiene and service reminders help staff maintain good operating routines.
• a&f can advise on water treatment, chemical setup, daily cleaning and ongoing service support.
