Maidaid D502 500mm Undercounter Glasswasher with Drain Pump

The Maidaid D502 is a 500mm undercounter glasswasher built for commercial bar and hospitality environments where consistent glass hygiene and reliable throughput are needed throughout service. It fits beneath a standard bar counter, connects to a mains water supply, and uses an onboard drain pump to handle waste removal — removing the dependency on a conveniently positioned floor-level drain point, which is often a practical constraint in bar installations.

In service, the D502 performs reliably across small to medium-volume operations. Three selectable wash programmes, including a dedicated renovation cycle for dulled or cloudy glassware, allow operators to match the programme to the load rather than defaulting to maximum resource on every cycle. A thermo-stop system holds the wash at the correct hygiene temperature before releasing, supporting repeatable results across busy service periods. An automatic self-clean function helps maintain the machine between shifts without requiring manual intervention each time.

A few operational features are worth noting:

• Onboard drain pump widens installation options by removing the need for gravity drainage
• Traffic light LED display gives clear cycle progress at a glance without reading a screen
• Energy saving mode reduces consumption during quieter periods between service
• Chemical dosing fitted as standard — no separate installation or additional equipment needed
• Double-skinned construction helps retain heat and keeps the external surface cooler to the touch

Installation requires a mains water connection, a suitable electrical supply, and a waste outlet. The unit carries WRAS approval, which matters on sites where water fittings compliance is a requirement. As with any undercounter glasswasher, ventilation around the unit is worth planning carefully, and the positioning beneath the counter should allow reasonable access for routine cleaning and periodic descaling.

The D502 is well suited to pubs, bars, small hotels, and event venues running moderate glass volumes through a single service point. It is not intended for high-volume operations processing several hundred covers per session — those environments would be better served by a higher-capacity machine with a faster cycle time or larger basket footprint. At the other end, very low-volume sites where a drain pump adds unnecessary cost may find a simpler model the more practical choice.

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