The final rinse temperature in a commercial dishwasher should be between 82-88°C. This range is important to make sure that your dishes are not only clean but also sanitised properly, eliminating harmful pathogens effectively.
Common misunderstanding: Any high temperature is good enough for the final rinse.
It's important to maintain the specific temperature range of 82-88°C. Temperatures lower than 82°C may not effectively kill bacteria, while temperatures higher than 88°C can cause damage to dishes or increase energy consumption unnecessarily.
Common misunderstanding: The final rinse temperature doesn't need to be checked regularly as long as the dishwasher is functioning.
Regular checks are important because even small deviations can affect the disinfection process. Consistently monitoring the temperature ensures compliance with food safety standards and maintains operational efficiency.
A rinse temperature within this range is very important for achieving thermal disinfection, which is necessary to eliminate 99% of microorganisms and bacteria from your dishes. This high level of sanitisation meets food safety regulations and prevents the spread of food-borne illnesses.
Common misunderstanding: Lower temperatures can be compensated by longer washing times.
While longer washing times might improve cleaning, they do not replace the need for a high-temperature rinse that ensures disinfection. The specific temperature range is required to effectively kill harmful pathogens.
Common misunderstanding: All bacteria are removed during the washing cycle, so rinse temperature is less critical.
The washing cycle removes food waste and grease, but the final high-temperature rinse is what ensures any remaining bacteria are killed. Both stages are important for complete sanitisation.
To accurately check the final rinse temperature, use temperature test strips that are designed to change color or indicate a specific temperature when they reach 82°C. These strips should be placed on the dishwasher rack during a cycle to ensure they are exposed to the rinse water.
Common misunderstanding: Using any thermometer will give an accurate reading of the rinse temperature.
Not all thermometers are suitable for the moist and hot environment inside a dishwasher. It's best to use specially designed dishwasher temperature test strips or thermometers that can withstand high temperatures and steam.
Common misunderstanding: It’s enough to check the temperature occasionally.
Temperature should be checked and recorded twice daily to ensure consistent compliance with food safety standards. Regular monitoring helps in identifying any issues early.

The correct wash temperature for a commercial dishwasher should be between 55-60°C to ensure that the alkaline chemicals in the detergents are activated effectively.
Biofilm in commercial dishwashers presents a major issue as it forms a protective layer that can harbour harmful bacteria, risking contamination of dishes and utensils and posing a threat to food safety. Biofilm is notably resistant to commonly used cleaning chemicals, making its removal challenging once it has been established.
Hard water contains high levels of minerals like calcium and magnesium, which contribute to the buildup of calcium carbonate in commercial dishwashers.
Dishwasher temperatures should be checked and recorded twice daily, typically once in the morning and once in the afternoon, to ensure that the dishwasher operates at the correct temperatures required for sanitising dishes effectively. This routine guarantees that the dishwasher maintains the necessary temperatures of 55-60°C for the wash cycle and 82-88°C for the final rinse for effective sanitation.
When your dishwasher is not working, switch to manual dishwashing by using a three-compartment sink as follows: (1) Wash dishes and utensils with hot, soapy water in the first compartment.
Regular maintenance of a commercial dishwasher is crucial to ensure efficient operation and maintain hygiene standards. Key tasks include checking and cleaning filters, spray arms, and seals.
If your dishwasher stops working during service, immediately cease its use to prevent worsening the problem.
