In every commercial kitchen, the dishwasher is one of the most heavily relied-on pieces of equipment. From breakfast cafés to large restaurant kitchens, dishwashers work constantly to keep plates, cutlery, and cookware clean and ready for service. When everything is running smoothly, staff barely notice the machine doing its job. When something goes wrong, however, the impact is immediate.
For many hospitality businesses in Melbourne, keeping the dishwasher running efficiently is essential for maintaining hygiene standards and keeping operations moving. At Commercial Kitchens Armiya, we repair commercial dishwashers across restaurants, cafés, catering kitchens, and hospitality venues. Over time, our technicians have seen a pattern in the types of issues that occur and how different brands tend to behave under heavy use.
Understanding these common problems can help kitchen operators identify issues early and avoid larger repairs.
Why Commercial Dishwashers Work Harder Than Most Equipment
Commercial dishwashers operate in demanding environments. Unlike your dishwashers at home that run a few times per day, commercial units may run dozens of cycles during a single service.
They are constantly exposed to:
- Constant heat and steam
- Food debris and grease buildup
- Hard water and mineral deposits
- Continuous opening and closing of doors
- Heavy racks and cookware loads
Over time, these conditions place strain on pumps, heating elements, seals, and electrical components. Regular servicing helps extend the life of these machines, but repairs still become necessary as equipment ages or components wear out.
Common Commercial Dishwasher Problems
Across Melbourne kitchens, our technicians frequently encounter several recurring dishwasher issues.
Poor Cleaning Results
One of the most common complaints is dishes coming out dirty or with food residue still present. This usually indicates:
- Blocked spray arms
- Worn wash pumps
- Clogged filters
- Low water pressure
- Detergent dosing issues
When spray arms become blocked by debris or limescale, water cannot circulate properly. This leads to inconsistent cleaning and longer wash cycles.
Routine cleaning and professional servicing can often resolve these issues before they affect service.
Water Not Heating Properly
Commercial dishwashers rely on high temperatures to ensure proper sanitisation. When water fails to reach the required temperature, dishes may appear clean but still fail hygiene standards.
Common causes include:
- Faulty heating elements
- Damaged thermostats
- Electrical supply issues
- Control board faults
Heating problems can also slow down wash cycles, reducing the number of racks processed during busy periods.
Drainage and Pump Failures
Drainage issues are another frequent repair request. When a dishwasher fails to drain correctly, water may remain in the tank or overflow.
Our Technicians often find:
- Blocked drain hoses
- Worn drain pumps
- Food debris obstructing the system
- Damaged valves
Drainage issues usually start small but can escalate quickly if ignored.
Leaks and Door Seal Damage
Leaks around the dishwasher are a clear sign that something requires attention. Water on the floor can create slip hazards for kitchen staff and damage nearby equipment.
Most leaks occur due to:
- Worn door gaskets
- Loose hose connections
- Damaged water inlet valves
- Cracked internal components
Replacing seals and tightening fittings can often resolve these issues quickly.
Brand-Specific Issues We Often See
Commercial kitchens across Melbourne use a variety of dishwasher brands, each with its own design and maintenance patterns. While all machines experience wear over time, certain issues appear more frequently with particular models.
Hobart Dishwashers
Hobart is one of the most widely used commercial dishwasher brands in Australia. Known for durability and strong wash performance, Hobart machines are common in high-volume kitchens.
Common issues CKA technicians see with Hobart units include:
- Wash pump wear after heavy use
- Scale buildup affecting heating performance
- Faulty rinse arms due to food debris
- Control board issues in older units
Regular descaling and cleaning help maintain Hobart machines in excellent condition.
Washtech Dishwashers
Washtech machines are popular for their efficiency and compact design, making them common in cafés and smaller kitchens.
Typical repairs involve:
Blocked rinse arms
Detergent dosing system faults
Pump wear after extended use
Sensor calibration issues
These machines perform well when maintained properly but benefit from routine servicing.
Meiko Dishwashers
Meiko dishwashers are known for advanced engineering and energy efficiency. They are often used in high-end hospitality venues and large kitchens.
Common service requests include:
- Drain pump faults
- Heating element issues
- Sensor alignment problems
- Software-related control errors
These machines often require specialised technicians familiar with their systems.
Signs Your Dishwasher Needs Attention
Many dishwasher issues develop gradually before leading to full breakdowns. Kitchen managers can often spot early warning signs such as:
- Longer wash cycles
- Water pooling at the bottom of the machine
- Unusual noises from pumps or motors
- Dishes coming out cloudy or greasy
- Steam escaping from door seals
Acting quickly when these signs appear can prevent larger repairs later.
The Value of Preventative Maintenance
Preventative maintenance plays a major role in extending the lifespan of commercial dishwashers. Routine servicing helps technicians identify worn components before they fail.
Regular dishwasher maintenance typically includes:
- Cleaning filters and spray arms
- Inspecting pumps and motors
- Checking heating elements and thermostats
- Inspecting seals and hoses
- Testing electrical components
These steps reduce downtime and keep dishwashers operating efficiently through busy service periods.
