Washmaster Underbench Commercial Glasswash WM40U

The Washmaster WM40U is a compact underbench glasswasher rated at 30 racks an hour, built in Italy in stainless steel with a digital control interface. High-temperature wash cycles sanitise rather than simply rinse, which is what keeps glassware compliant with Australian hygiene practice. At 436 mm wide it fits a standard underbench cavity in a bar or cafe.

Why operators choose the WM40U

• 30 racks per hour — enough turnaround to keep a bar in clean glassware through a peak without a second machine
• 436 mm underbench footprint — the narrowest of the Washmaster range — fits a bar cavity where a dishwasher will not
• High-temperature sanitising cycles — the cycle sanitises rather than just washing, which is the requirement on glassware that goes straight back into service
• Digital control interface — simple enough that staff training is not a project, with repeatable cycle selection
• Stainless steel construction — survives the constant moisture and chemical exposure of a glasswash station
• Made in Italy — a European-built machine rather than a generic import, which matters for parts availability
• 31 kg — light enough for a two-person install into an existing cavity
• Glass-specific rather than a small dishwasher — designed around racks of glassware, which is a different wash pattern to plates

Specifications

Venue suitability

The WM40U suits bars, cafes, clubs and small restaurants washing glassware under the counter. At 436 mm it is the compact option in the Washmaster range — step up to the WM50U for plates as well as glasses, or the WM50H passthrough for double the throughput.

Installation & delivery

The electrical supply for this model is not recorded in our product data. A machine of this type draws far more than a general-purpose appliance and its supply must not be assumed, so contact our team to confirm the requirement before you order or book a trade. It needs a water supply, a waste connection and a 436 mm underbench cavity, so a licensed plumber should make the water connections. Confirm both the electrical supply and the cavity dimensions before install. Dispatched from our Sydney HQ with partner warehouses in Melbourne, Brisbane, Adelaide and Perth for faster delivery Australia-wide. Backed by a 2-year parts and labour warranty — see our warranty information page for full terms.

Frequently asked questions

Q: What electrical supply does the WM40U need? A: Our product data does not record it. A commercial glasswasher draws far more than a general-purpose appliance and the supply must not be assumed, so contact our team to confirm the requirement before you order or book a trade.

Q: How many racks can it wash per hour? A: 30, which is sized for a bar or cafe keeping glassware moving through a peak.

Q: Will it fit under a standard bench? A: It is 436mm wide, 535mm deep and 815mm high. Measure your cavity against those figures, particularly the height once the bench substrate is accounted for.

Q: Does it sanitise or just wash? A: It runs high-temperature sanitising cycles, which is the requirement for glassware returning straight to service rather than a rinse-only wash.

Q: How does it compare with the WM50U and WM50H? A: The WM40U is the compact glasswasher at 436mm and 30 racks/hour. The WM50U is an underbench dishwasher at 575mm, also 30 racks/hour, with a double-skinned door and built-in chemical dispensers. The WM50H is a passthrough dishwasher at 60 racks/hour.

Q: What warranty applies? A: Two years parts and labour.
