Commercial Dishwasher Not Heating: Technical Breakdown
A commercial dishwasher usually heats wash water in the tank and may use a separate booster to achieve the specified final-rinse condition. A machine can therefore wash warm but rinse cold, delay indefinitely while heating, or display a plausible temperature that does not match the process. Read more...
Commercial Kitchen Equipment Duty Categories
Commercial kitchen equipment duty categories describe the intensity of the cooking plume a ventilation system must capture. They are commonly expressed from light through medium and heavy to very heavy duty. The category is not simply a description of appliance size: cooking process, heat, grease, smoke, steam, fuel and use all affect the design classification. Read more...
Commercial Kitchen Odour-Control Systems Guide
Commercial kitchen odour control normally uses a treatment train, not one magic filter. Grease and smoke particles should be reduced before gaseous odour treatment, then the cleaned air needs an appropriate discharge location. The correct combination depends on cooking type, airflow, contaminant load, available space, planning risk, pressure drop and maintenance capability. Read more...
What Is an EMAQ+ Kitchen Odour Assessment?
An EMAQ+ kitchen odour assessment is a structured assessment used to consider the risk of cooking odour affecting nearby sensitive receptors and to identify an appropriate control and discharge strategy. It is commonly used to support planning and environmental-health review. EMAQ+ guidance is not legislation and an assessment does not guarantee planning approval. Read more...
Fryer High-Limit Thermostat Keeps Tripping: Causes
The high-limit thermostat is an independent safety control intended to stop heating if the frying medium becomes excessively hot. If it operates repeatedly, either the fryer is genuinely overheating or the safety circuit, sensor position or wiring is unreliable. Read more...

When a combi oven trips an MCB, RCBO or RCD, the protective device is responding to overcurrent, earth leakage or another abnormal condition. The point in the cycle—start-up, heating, steaming, washing or draining—is one of the most useful diagnostic clues. Read more...
Bain-Marie Not Holding Temperature: Technical Guide
A bain-marie is primarily a hot-holding appliance, not a rapid reheater. Poor performance may come from loading cold food, missing lids, wrong water level or pan arrangement, but failed heaters, controls and sensors can also prevent safe holding. Read more...

A gas interlock refusing to open the solenoid valve is usually doing exactly what it was designed to do: withholding gas until ventilation and other safety conditions are proved. The correct response is to identify the failed input, not bypass the panel. Read more...
