Washmaster Underbench Commercial Dishwasher WM50U

The Washmaster WM50U is an underbench commercial dishwasher rated at 30 racks an hour, with a double-skinned door that cuts heat loss and noise, and built-in detergent and rinse aid dispensers so both chemicals are dosed by the machine rather than by hand. Built in Italy in stainless steel with programmable digital cycles, it fits under a standard bench at 575 mm wide.

Why operators choose the WM50U

• Double-skinned door — two skins cut both heat loss and running noise — the difference between a machine you can site behind a bar and one you cannot
• Built-in detergent and rinse aid dispensers — both chemicals dosed by the machine, so wash results do not depend on someone measuring correctly
• 30 racks per hour — sized for a cafe, bar or small restaurant keeping plateware and glassware moving
• 575 mm underbench footprint — fits a standard bench cavity, freeing the floor space a freestanding machine would take
• Quiet operation — a genuine consideration in an open or customer-facing space, and a direct result of the double-skinned door
• Programmable digital cycles — select a cycle for the load rather than running everything on one setting
• High-temperature sanitising — the wash sanitises rather than simply cleaning, meeting food-safety practice
• Made in Italy in stainless steel — a European-built machine that survives constant moisture and chemical exposure

Specifications

Venue suitability

The WM50U suits cafes, bars, small to medium restaurants and hotel kitchens washing plateware under the counter. The double-skinned door makes it the sensible choice where the machine sits within earshot of customers; step up to the WM50H passthrough if volume outgrows 30 racks an hour.

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 575 mm underbench cavity — check the 825 mm height against your cavity once the bench substrate is accounted for. A licensed plumber should make the water connections. 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 WM50U need? A: Our product data does not record it. A machine of this type 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: What does a double-skinned door do? A: Two skins with a gap between them cut heat loss from the wash chamber and noticeably reduce running noise. That matters when the machine sits behind a bar or in an open kitchen.

Q: Do I need to dose the chemicals manually? A: No. Detergent and rinse aid dispensers are built in, so both are dosed by the machine. Manual dosing is the usual reason wash results vary between staff.

Q: Will it fit under a standard bench? A: It is 575mm wide, 605mm deep and 825mm high. Measure your cavity against those figures, particularly the height once the bench substrate is accounted for.

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

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