Junhong Electrical Repair: Professionally solves the problem of water hood not pumping water when turned on and cleaning oil stains

In the catering industry, water fume hoods are important equipment in the kitchen. They can not only effectively eliminate the oil fume generated by cooking, but also keep the interior clean through the automatic cleaning function and extend the service life of the equipment. However, in actual use, water hoods occasionally encounter problems such as not pumping water after starting up and being unable to clean oil stains. This article will introduce in detail how Junhong Electrical Repair Team solves these problems professionally and efficiently, and share a complete set of repair steps and processes.

1. Problem diagnosis and preliminary inspection

When the water fume hood fails to pump water and cannot clean oil stains after being turned on, problem diagnosis and preliminary inspection are first required. Junhong Electrical Appliance Repair Team usually follows the following steps:

Check the power supply and power cord: Confirm whether the power plug is firmly inserted into the socket and whether the power cord is damaged or loose. If there is a problem with the power cord, it should be replaced in time.

Check the display and error codes: Water hoods are usually equipped with a display to show the current working status and error codes. If an error code (such as E01, E02, etc.) appears on the display, you need to interpret it according to the device manual and take corresponding solutions.

Check the water source and water supply pipe: Confirm whether the water supply pipe is smooth and whether the water source is supplied normally. Sometimes too much air or insufficient water pressure in the water supply pipe can also affect the pumping function.

Observe the status of the cleaning water pump: The cleaning water pump is a key component of the automatic cleaning function of the water fume hood. Check whether the water pump is working properly and whether there is any abnormal noise or water leakage.

2. Professional maintenance steps

After preliminary inspection, Junhong Electrical Appliances maintenance team will take the following professional maintenance steps according to the specific fault situation:

1. Solve the problem of no water pumping at startup

Check and replace the power switch: If the error code is E01, there is a problem with the power supply. At this time, check whether the power switch is damaged and replace it if necessary.

Clean or replace the drainage pump: If the error code is E02, it means there is a problem with the drainage system. First check whether the drainage pipe is clogged, clear the blockage and then test again. If the problem persists, the drain pump may be damaged and needs to be replaced with a new pump.

Check and repair the circuit board: A faulty circuit board may also cause the pumping function to fail. Use tools such as a multimeter to check whether the components on the circuit board are normal, and replace them in time if they are damaged.

Adjust the water supply pressure: If there is too much air or insufficient water pressure in the water supply pipe, the water supply system needs to be adjusted to ensure stable and sufficient water pressure.

2. Solve the problem of being unable to clean oil stains

Clean or replace the cleaning water pump: Failure of the cleaning water pump is a common reason why oil stains cannot be cleaned. First try to clean the inside of the water pump. If cleaning is ineffective, replace the pump with a new one.

Check and repair water supply lines: Clogged or leaking water supply lines will also affect the cleaning effect. Check whether the water supply pipeline is smooth. If there is any blockage, clean it in time. If there is water leakage, the pipeline needs to be repaired or replaced.

Adjust the cleaning program: Sometimes improper cleaning program settings can also lead to poor cleaning results. Adjust the cleaning program parameters according to the equipment instructions to ensure that the cleaning process meets the equipment requirements.

Deep clean the inside of the hood: excessive accumulation of oil will also affect the cleaning effect. During the maintenance process, the inside of the hood should be deeply cleaned to completely remove oil stains and impurities.

3. Precautions during maintenance

In the process of repairing the hookah hood, Junhong Electrical Maintenance Team always follows the following precautions:

Safety first: Be sure to cut off the power supply before repairing to prevent electric shock accidents. Also wear personal protective equipment such as protective gloves and glasses.

Careful inspection: Carry out detailed inspection on every possible faulty part to ensure that no potential problems are missed.

Professional operation: During the maintenance process, the equipment instructions and maintenance manuals should be strictly followed to avoid equipment damage or personal injury caused by improper operation.

Record the maintenance process: record every step of the maintenance process and problems found in detail for subsequent tracking and review.

Customer communication: Communicate with customers on maintenance progress and discovered problems in a timely manner to ensure that customers understand the maintenance situation and are satisfied with the maintenance results.

4. Case sharing

The following is a case shared by Junhong Electrical Appliances maintenance team that successfully solved a problem of water fume hood not pumping water when turned on and unable to clean oil stains:

A certain restaurant's water fume hood suddenly failed to pump water and could not clean oil stains after it was turned on. The person in charge of the restaurant contacted the Junhong Electrical Maintenance Team for help. After the maintenance team arrived at the scene, they first conducted a preliminary inspection and found that the power cord and power switch were normal, but the error code E02 was displayed on the display. Subsequently, the maintenance team conducted a detailed inspection of the drainage system and found that the drainage pipes were seriously blocked by oil. After clearing the blockage, test the pumping function again and return to normal. However, the cleaning function still does not work properly. The maintenance team further inspected the cleaning water pump and water supply pipeline and found that there was foreign matter stuck inside the cleaning water pump, causing it to fail to work properly. After cleaning the water pump and replacing damaged parts, the cleaning function returned to normal. In the end, the restaurant's water fume hood was successfully restored to normal operation with the help of Junhong Electrical Maintenance Team. The restaurant's fume emission and internal cleaning problems were effectively solved, and customer satisfaction was greatly improved.

5. Testing and maintenance suggestions after repair

After the repair is completed, Junhong Electrical's maintenance team will conduct a series of tests to ensure that all functions of the hookah hood are restored to normal. The test content includes but is not limited to: water pumping function test, cleaning function test, power supply stability test and error code display function test. Only when all tests pass and the equipment runs stably for a period of time is the repair work truly completed.

In addition, in order to extend the service life of the hookah hood and reduce the possibility of failure, the Junhong electrical maintenance team will also provide customers with some maintenance suggestions:

Regular cleaning: It is recommended that restaurants regularly clean water fume hoods, especially oil fume filters and internal pipes, to prevent excessive accumulation of oil from affecting equipment performance.

Check the water source and water supply pipes: Check the water source and water supply pipes regularly to ensure that the water quality is clean, the water pressure is stable, and the water supply pipes are not clogged or leaking.

Pay attention to electrical safety: When using a water smoke hood, pay attention to electrical safety, avoid overloading or short-circuiting the power line, and regularly check whether the power cord and plug are damaged.

Timely maintenance: Once any abnormality or malfunction is found in the water smoke hood, a professional maintenance team should be contacted promptly to handle it to avoid the problem from expanding and causing more serious damage.
