Maidaid D502 500mm Undercounter Glasswasher with Drain Pump

The Maidaid D502 is a 500mm undercounter glasswasher designed for commercial bar and hospitality environments where consistent glass hygiene and reliable throughput are essential during service. It operates as a standalone unit that sits neatly beneath a bar counter, connecting to the water supply and draining via an onboard pump rather than relying on gravity — a practical advantage in installations where the drain point is not conveniently positioned below the machine.

In service, the D502 is well suited to small to medium-volume operations. It can wash a meaningful batch of pint glasses per cycle, and three selectable wash programmes — including a "Pro Long" setting for renovating glasses that have dulled over time — allow operators to match the wash to the load rather than running every cycle at maximum resource. The thermo-stop system holds the wash at the correct temperature before releasing, which supports consistent hygiene results rather than relying purely on cycle time. An automatic self-clean cycle helps maintain the machine between service periods without manual intervention.

From an operational standpoint, the D502 offers several practical advantages worth noting:

• Onboard drain pump removes reliance on gravity drainage, widening installation options
• Traffic light LED display gives clear, at-a-glance wash cycle progress without needing to read a display
• Energy saving mode reduces running costs during quieter periods
• Chemical dosing fitted as standard — no need for separate installation
• Double-skinned construction helps retain heat and reduces external surface temperature

Installation requires a mains water supply, a suitable electrical connection, and a waste outlet — the drain pump handles the lift if needed. The unit is WRAS approved, which is relevant for sites where water fittings compliance is a requirement. As with any glasswasher, adequate ventilation above and around the unit is worth planning for, and access to the interior for routine cleaning and descaling should factor into how the machine is positioned beneath the counter.

The D502 is a sensible choice for bars, pubs, small hotels, and event spaces running moderate glass volumes through a single service point. It is not intended for high-volume operations washing multiple hundreds of covers per session — for those environments, a higher-capacity machine with a larger basket or faster cycle time would be more appropriate. Equally, for very low-volume sites, a simpler model without the drain pump may represent better value.

If you are unsure whether the D502 matches your service volume or installation setup, the team is happy to talk it through before you commit to a purchase.
