Fast Wash Cycles

Selectable cycles from 60 seconds — keeping pace with high-turnover service periods. The GS 40T offers 60/90/120/180 second options so operators can match cycle time to soil load and throughput demand.

💧

Efficient Water Use

The GS 40T uses only 1.8 litres per cycle — highly efficient for an undercounter glasswasher. Built-in rinse aid and detergent dispensers are standard, with a non-return valve and drain pump included.

Full Pot Washer Range

From the LP1 S4 undercounter entry through to the LP4 S8 TR Plus upright with heat recovery — DIHR covers every pot washing requirement from small café to large institutional kitchen.

Heat Recovery on Pot Washers

DIHR's TR (Thermo Recovery) system on STR and S8 TR upright pot washer models captures exhaust heat to pre-heat incoming water — reducing energy consumption for high-cycle operations.

DIHR Full Range — All 16 Models

Undercounter glasswashers and dishwashers, passthrough hood dishwashers, and pot washers from undercounter to large-capacity upright.

Undercounter Glasswashers & Dishwashers

Passthrough Hood Dishwashers

Installation note: Hood-type passthrough dishwashers require a mechanical ventilation canopy. Confirm ventilation requirements with your kitchen designer or council before specifying.

Pot Washers — Undercounter, Hood-Type & Upright

DIHR's pot washer range covers every scale of operation — from the LP1 S4 undercounter entry unit through to the high-capacity LP4 S8 TR Plus upright with heat recovery. TR suffix models reduce energy costs through exhaust heat recapture.

Frequently Asked Questions — DIHR Commercial Warewashing

What is DIHR and where are DIHR dishwashers made?

DIHR is an Italian commercial warewashing brand — all DIHR equipment is made in Italy. The range delivers reliable Italian performance with fast wash cycles, consistent hygiene results, and efficient operation for busy hospitality and foodservice venues. Industry Kitchens is an authorised DIHR dealer with national coverage and SilverChef finance options.

What warranty do DIHR dishwashers carry in Australia?

DIHR products carry a 24-month parts and 24-month labour warranty — a full two-year warranty on both parts and labour. This is twice the 12-month standard offered by most competing brands in the Australian market. Industry Kitchens can assist with all warranty claims nationally — contact us with your model and serial number.

What are the specifications of the DIHR GS 40T glasswasher?

The DIHR GS 40T has a 400×400mm rack, 1.8 litres per cycle, four selectable wash cycles (60, 90, 120, 180 seconds), double-skin door with safety switch, built-in drain pump, non-return valve, and built-in rinse aid and detergent dispensers. Power: 3.45kW at 240V/15A single phase. Dimensions: 450×535×700mm. Weight: 37kg. Supplied with 2 glass baskets, 1 saucer holder, and 1 cutlery basket. Maximum glass/dish height: 305mm. 24-month parts and labour warranty.

What power does the DIHR GS 40T require?

The DIHR GS 40T runs on 240V/15A single phase at 3.45kW. This requires a dedicated 15-amp single-phase circuit — standard for undercounter warewashing in Australian commercial kitchens. A licensed electrician must install the dedicated circuit if one is not already present at the installation point.

What is the difference between the DIHR GS 40T and OPTIMA 400?

Both are undercounter machines with a 400mm rack. The GS 40T is a dedicated glasswasher, while the OPTIMA 400 is a combination glass, dish, and cutlery washer — suited to venues that need one machine to handle all ware types in a 400mm format. Contact Industry Kitchens to compare specifications for your specific application and ware types.

What is the difference between the DIHR H 11 ECO T and H 11 T?

Both are hood-type passthrough dishwashers in the DIHR H 11 series. The H 11 ECO T is the energy-efficient variant designed to reduce water and energy consumption per cycle. The H 11 T is the full-spec standard passthrough. Both require a mechanical ventilation canopy for installation. Contact Industry Kitchens for a full specification comparison to match your site's throughput requirements.

When do I need a DIHR pot washer and which model?

DIHR pot washers are specified when you need to wash large pots, gastronorm containers, mixing bowls, baking trays, and oversized items that don't fit in standard 400mm or 500mm rack machines. Start with the LP1 S4 (undercounter, small operations) or LP1 400 PLUS (wide-body hood-type). For higher volume, the LP1–LP4 upright chamber range scales up progressively — LP4 being the largest. Add TR (Thermo Recovery) on any upright model when the machine will run many cycles per shift and energy efficiency matters.

What is the DIHR TR Thermo Recovery system on pot washers?

DIHR's TR (Thermo Recovery) system captures heat from exhaust steam and uses it to pre-heat incoming water — reducing energy consumption per cycle. Available on the LP1 S8 TR Plus, LP2 STR Plus, LP3 STR Plus, and LP4 S8 TR Plus upright pot washers. Recommended for high-throughput operations running many cycles per shift — the energy saving compounds significantly with high cycle counts.

What is the difference between LP1, LP2, LP3, and LP4 pot washers?

LP1 through LP4 represent progressively larger chamber sizes in DIHR's upright pot washer range — LP1 is the entry and LP4 the largest capacity. Each is available in standard (S/S8) or heat recovery (STR/S8 TR) configurations. Chamber size determines the maximum item height and hourly throughput. Contact Industry Kitchens for a site-specific recommendation based on your operation's peak cycle demand.

Is SilverChef finance available for DIHR equipment?

Yes — SilverChef Rent-Try-Buy finance is available on DIHR dishwashers, glasswashers, and pot washers through Industry Kitchens. A 10% refundable holding deposit is required to secure the order. Contact Industry Kitchens for a finance quote on any DIHR model.
