The PTD 901 is best suited to busy commercial kitchens and larger dishwashing areas where baskets need to move quickly through the wash process. It is particularly relevant where staff are washing crockery, glasses, trays and general catering items throughout the working day.

• Suitable for hotels, restaurants, bars, guesthouses, canteens, schools, universities, sports clubs, childcare facilities, care homes and healthcare-related environments.
• Useful where the site needs a passthrough dishwasher rather than an undercounter model.
• Suitable where typical quick wash times of around 1 to 3 minutes support the required workflow.
• Appropriate where the wash-up area can support a clear dirty-side to clean-side process.
• Good for sites that need professional dosing, water treatment or heat recovery options, depending on the selected variant.

The most important checks are services, space, water quality, drainage, ventilation and daily throughput. The PTD 901 variants share the same core platform, but the WES DOS ECO version has different service and height requirements.

• Check whether the site has the correct electrical supply for the chosen variant and connection option.
• Confirm available height, especially if considering the WES DOS ECO variant at 2175 mm high.
• Check water quality and whether an integrated water softener is needed.
• Confirm drainage position and that the drain pump arrangement is suitable.
• Review staff workflow, including loading tables, exit tables and basket handling.
• Confirm whether integrated detergent dosing is required or whether an external detergent module is acceptable.

The standard PTD 901 is the base passthrough dishwasher. The PTD 901 [DOS] adds integrated detergent dosing. The PTD 901 [WES DOS ECO] adds integrated detergent dosing, an integrated water softener, waste water and exhaust air heat recovery, and vapour extraction.

• PTD 901: suitable where the site wants a professional passthrough dishwasher and is happy to use an external liquid detergent dosing module.
• PTD 901 [DOS]: suitable where integrated detergent and rinse aid dosing are preferred for simpler day-to-day chemical management.
• PTD 901 [WES DOS ECO]: suitable where the site needs integrated dosing, an integrated water softener, reduced steam release and heat recovery.
• Choose WES DOS ECO carefully where ceiling height, cold water supply and room layout have been checked.

The PTD 901 is not the right choice for every site. Some locations may be better served by an undercounter dishwasher, a fresh-water dishwasher, a larger rack or utensil washer, or a simpler machine where staff routine and budget are the main priorities.

• Choose an undercounter dishwasher where space is limited or basket volumes are modest.
• Consider a fresh-water dishwasher where the site specifically requires fresh water for every wash cycle.
• Consider a larger dishwasher or separate utensil solution if the site regularly washes large pans, trays or kitchen equipment.
• Consider a simpler Classeq dishwasher where simplicity, straightforward operation and service continuity are more important than the Miele specification.
• Review the full dishwashing process if staff are struggling with scraping, racking, pre-rinse, chemical changes or daily cleaning routines.

The PTD 901 range has several electrical connection options, and the right choice affects heat-up, recovery and suitability. Miele lists a shortest programme duration from 50 seconds, but this should be treated as an advertised optimum rather than a typical working promise.

• In normal use, a practical quick wash is more usually around 1 to 3 minutes once the machine is up to temperature.
• PTD 901 and PTD 901 [DOS]: 400v options, with 16A, 25A or 32A configurations depending on connection.
• PTD 901 [WES DOS ECO]: 400v, 16A or 25A options, plus a 230v, 32A option.
• PTD 901 and PTD 901 [DOS]: cold or hot water connection up to 60°C.
• PTD 901 [WES DOS ECO]: cold water connection up to 20°C, with integrated water softener.
• All variants use a DN 19 drain pump, with maximum drain pump head height from floor level of 65 cm.
• Actual cycle and recovery times depend on incoming water temperature, water pressure, power supply, programme and site routine.

If the PTD 901 is replacing an older passthrough dishwasher, the key checks are not just width and depth. Hood height, open-hood clearance, table arrangement, drain height, water treatment, power supply and chemical dosing all need to be reviewed before ordering.

The current a&f historic mapping source does not list a confirmed PTD 901 predecessor model. For website search and replacement enquiries, this page can still support customers searching for older Miele passthrough dishwasher, Miele throughfeed dishwasher and Miele hood dishwasher installations.

Relevant replacement and search terms to review with a&f include older Miele passthrough dishwasher, Miele throughfeed dishwasher, Miele hood dishwasher and G8072-style throughfeed dishwasher installations. Exact old model suitability should be confirmed from the machine data plate before specifying the replacement.

The PTD 901 range supports professional hygiene routines through high final rinse temperatures, tested virucidal efficacy, a hygienic tank wash cabinet, filtration and controlled dosing options. It should still be specified as part of a complete dishwashing process, including scraping, racking, chemical supply, daily cleaning and staff training.

• The datasheets confirm tested virucidal efficacy and a maximum final rinse temperature of 90°C.
• The machine is WRAS listed and carries CE, UKCA, IPX5, DIN EN 17735 and DIN SPEC 10534 references in the product sheets.
• For care, healthcare and food-service sites, hygiene depends on the full process, not the dishwasher alone.
• WES DOS ECO can help reduce steam release into the room through vapour extraction.
• a&f can help check whether this machine, or another dishwasher type, is the right fit for the site’s hygiene, workload and staff routine.
