Maidaid D3121 500mm Pass Through Dishwasher with Drain Pump

The Maidaid D3121 is a 500mm basket pass through dishwasher designed for high-volume commercial kitchens running on three-phase power. It sits at the heavier end of the pass through category, built for sites where throughput, reliability, and wash quality under sustained pressure are non-negotiable. A fitted drain pump and break tank are included as standard, which simplifies installation in most kitchen configurations and removes the need for elevated drainage positioning.

In busy service environments, the D3121 is well suited to the demands of back-to-back cycles. The patented dual flow wash pump with soft start reduces the initial power draw without compromising wash performance, which is a practical advantage on sites with sensitive electrical loading. Triple filtration in the wash tank keeps water cleaner across longer service periods, and the quick-release parallel wash and rinse arms deliver consistent coverage without requiring tools to remove for cleaning. Automatic self-cleaning at the end of service reduces the manual effort required from kitchen staff during breakdown.

From an operational standpoint, the D3121 offers several practical advantages worth noting:

• Cycle times can be adjusted to match specific site requirements and service patterns
• Selectable thermostop function helps maintain correct rinse temperatures for hygiene compliance
• Peristaltic dosing pumps for detergent and rinse aid are fitted as standard, reducing manual dosing errors
• Selectable energy saving mode helps manage running costs during quieter periods
• LED display with soft touch controls and twin traffic light indicators gives staff clear, at-a-glance machine status

Installation requires a three-phase power supply, so this machine is not suitable for sites with single-phase supply only. A break tank is fitted as standard, meeting water regulations without additional plumbing intervention in most cases. Inlet and drainage positions should be confirmed against your kitchen layout before ordering, and tabling — both feed and exit — is not included and will need to be specified separately. The machine's footprint and hood clearance should be checked against your pass through position, particularly in tighter or galley-style kitchens.

The D3121 is best suited to mid-to-high volume operations — restaurants, hotels, contract catering, staff canteens, and similar environments where a glasswasher or light undercounter machine would be insufficient. If your site runs lower volumes or has single-phase supply, a smaller undercounter or lower-powered pass through may be more appropriate. Conversely, very high-volume operations such as large banqueting facilities or central production kitchens may benefit from reviewing higher-capacity alternatives in the range.
