Washtech TW Undercounter Traywasher – 500mm Rack, 15A

Washtech has been engineering commercial dishwashers since 1981 and is recognised across
Australia and New Zealand for durable stainless-steel construction, serviceability, and designs aligned to
local conditions and regulations.

• Local-fit engineering – designed for Australasian sites
• Heavy-duty stainless build – made for harsh wash rooms
• Service network support – parts and technicians available locally
• Operator-friendly controls – fast training and consistent results

The Washtech TW is designed for the tasks that slow a kitchen down: baking trays, mixing bowls,
prep containers, cups and cutlery. Instead of long manual scrubbing, you can run consistent 2-minute
or 4-minute cycles, therefore improving throughput and hygiene during peak production.

Most importantly, the TW uses an oversized chamber and robust wash/rinse systems to handle bulky ware
more effectively than a standard undercounter dishwasher.

This utensil washer provides a larger internal chamber with a usable area of W 800mm × D 545mm × H 470mm,
making it suitable for bakery trays and larger kitchenware that won’t fit comfortably in many standard machines.

Washtech Hybrid Controls combine stainless steel IP65 switches with proven switchgear and a
customisable electronic timer, keeping operation simple while maintaining durability.

• Water supply hose
• Dual detergent and rinse aid pumps with injector lines and chemical level sensors
• Drain pump with outlet hose

• Hot water inlet: 65°C, potable water
• Inlet connection: 3/4" BSP male (hose supplied)

Installation and servicing must be carried out by qualified personnel in compliance with local codes and standards
(including AS/NZS 3500.1). Ensure the isolating switch is accessible and located within 1m of the machine (not directly behind it),
and the isolating water valve is readily accessible.

• Pre-scrape / pre-rinse – remove loose soil first to protect pumps and filtration
• Use correct chemicals – commercial low-foam detergent and rinse aid only
• Drain daily – run drain at end of day and leave door open to air dry
• Weekly deep clean – clean scrap trays, filters, and inspect jets for blockages

• 500mm rack undercounter traywasher for utensils & baking trays

• 2 & 4 minute cycles, 3.3L hot water per cycle
• QuikConnect Plug & Play kit with pumps, hoses and drain pump

Check your largest item against the usable chamber size: 800(W) × 545(D) × 470(H)mm. If unsure, send us your tray dimensions and we’ll confirm fitment.

This model is specified for 65°C hot water, 200–350kPa inlet pressure, and minimum 20 L/min flow. If your pressure is above range, fit a limiter; if below, consult a technician about booster options.

Use commercial low-foam dishwasher detergent only, calibrate dosing for your water quality, and pre-scrape items. Domestic detergents and soap carry-over from sinks are common causes of foaming.

Drain daily, rinse scrap trays and filters once the machine has cooled, and keep jets clear. Weekly: remove wash/rinse arms and inspect jets for blockages.
