Chafing dishes, an essential piece of equipment for maintaining food temperature and enhancing meal delivery efficiency, are directly related to both customer experience and kitchen operation efficiency. As a professional buffet equipment manufacturer, Dongzhaowei has always been committed to providing customers with high-quality and easy-to-maintain products. Today, we will introduce you to common faults and solutions for chafing dishes.

Fault 1: The chafing dish does not heat or heats unevenly

Possible reasons:

• The power supply is not connected, or the switch is not turned on.
• The electric heating plate is damaged or has poor contact.
• Thermostat failure or temperature sensor failure.
• Fuel heating chafing dish: alcohol fuel is exhausted or not fully burned.

Solution:

• Confirm whether the power plug is firmly inserted and the power switch is turned on.
• Check whether there is obvious damage on the surface of the heating plate, and contact the manufacturer for replacement if necessary.
• Reset or replace the thermostat to eliminate sensor failure.
• For a fuel-chafing dish, replace the fuel in time and keep the burner clean.

Fault 2: The lid does not open and close smoothly

Possible reasons:

• Dust or oil accumulation causes jamming.
• The hinge of the slow-drop lid is not lubricated enough or deformed.

Solution:

• Clean the lid and hinge regularly to avoid oil accumulation.
• Use food-grade lubricant to lubricate the hinge regularly.
• If the hinge is deformed, replace the relevant accessories in time to ensure normal opening and closing.

Fault 3: The heating tray is deformed or leaking

Possible reasons:

• Improper cleaning causes cracks in the tray.
• Defects in the tray material or manufacturing process.
• Long-term high-temperature heating causes fatigue deformation of the tray material.

Solution:

• Avoid using sharp tools for cleaning, and soft cloth and neutral detergent are recommended.
• Choose a 304 stainless steel tray, which has higher heat resistance and corrosion resistance.
• Check the tray status regularly and replace it in time if cracks are found.

Fault 4: The fuel chafing dish is not completely burned and produces an odor

Possible reasons:

• The combustion port is blocked or the fuel quality is poor.
• Insufficient alcohol or alcohol evaporates too quickly.

Solution:

• Clean the combustion port regularly to keep it unobstructed
• Choose high-quality alcohol fuel to avoid impurities affecting combustion.
• Ensure that the fuel filling amount is sufficient to prevent combustion interruption.

Fault 5: Failure of the control panel of the electric chafing dish

Possible reasons:

• The control panel line is loose or damp.
• Internal electronic components are damaged.

Solution:

• Check the line connection and keep the equipment dry.
• If a panel failure is found, it is recommended to contact the after-sales professional repair to avoid unauthorized disassembly.

Recommended table for the maintenance cycle of the chafing dish

Regular maintenance is the guarantee for extending the service life of the equipment and maintaining efficient operation. We have specially compiled a recommended maintenance cycle table for different components for you.

Component	Maintenance frequency	Recommended operation
Heating plate/burner	After each use	Clean the surface to remove residual oil and charred stains
Control panel	Monthly	Wipe with a dry cloth, keep dry and check whether the button is sensitive
Hinge/slow-down lid	Quarterly	Lubricate once a quarter to check whether it is smooth
Internal circuit	Every six months	Have professionals check the safety and prevent aging and loosening

Key operation suggestions for chafing dish faults and solutions

Standardized use and avoiding misoperation can not only improve the stability of the equipment but also reduce after-sales maintenance costs:

• Use original factory-recommended accessories and fuel.
• Regularly train operators to reduce losses caused by misoperation.
• Large catering companies are advised to establish an equipment inspection system and record each maintenance situation.
• It is strictly forbidden to burn without heating. Make sure there is enough water in the water pan to avoid dry burning and damage to the heating components.
