Washmaster Passthrough Commercial Dishwasher WM50H

The Washmaster WM50H is a passthrough dishwasher rated at 60 racks an hour — double the throughput of the underbench machines in this range. The passthrough design is the point: racks enter one side and leave the other, so a dishroom runs as a line rather than a queue at a single door. Built in Italy in stainless steel, with programmable cycles and high-temperature sanitising.

Why operators choose the WM50H

• 60 racks per hour — twice the throughput of the underbench WM50U, which is what a busy dishroom needs at the end of service
• Passthrough hood design — racks go in one side and out the other, so loading and unloading do not compete for the same space
• High-temperature sanitising cycles — the wash sanitises rather than simply cleaning, meeting food-safety practice on plateware
• Programmable cycles — different cycles for glassware, plates and heavily soiled pans, selected rather than improvised
• Stainless steel construction — survives constant heat, moisture and chemical exposure in a dishroom
• Made in Italy — a European-built machine rather than a generic import, which matters for parts and service
• Compact footprint for the capacity — 634 x 928 mm on the floor for 60 racks an hour
• 1529 mm hood height — allow for the hood to raise fully — the figure that decides whether it fits under a shelf

Specifications

Venue suitability

The WM50H suits restaurants, pubs, clubs, hotels and catering kitchens with a dedicated dishroom and enough volume to justify a passthrough. If the room cannot be laid out as a line — dirty in one side, clean out the other — an underbench machine such as the WM50U is the better fit.

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 enough room to open the hood to its full 1529 mm height, plus clear space either side for the passthrough workflow to actually work. 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 WM50H need? A: Our product data does not record it. A passthrough dishwasher at this capacity 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 per hour? A: 60, which is double the 30 racks/hour of the underbench WM50U and WM40U.

Q: What does passthrough actually change? A: Racks enter one side and leave the other, so loading and unloading happen in separate places. In a busy dishroom that removes the bottleneck of everything queueing at a single door.

Q: How much height does it need? A: 1529mm with the hood raised. That is the figure to check against any shelf or extraction above it, not the closed height.

Q: How does it compare with the WM50U? A: The WM50H is the passthrough at 60 racks/hour and needs a dishroom laid out as a line. The WM50U is an underbench machine at 30 racks/hour that fits under a standard bench.

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