Car Wash Machine Daily Maintenance Guide: 8 Essential Checks for Reliable Operation

1. Check the Air Pressure

Start by checking the air pressure of the system. Confirm that the pressure reading is within the normal operating range before beginning daily operation.

The compressed-air system should also be checked for proper operation and any abnormal condition should be addressed before the car wash machine is used.

2. Test the Emergency Stop

Check the emergency stop function before operating the machine. The emergency stop is an important safety device and should respond correctly when activated.

When maintenance personnel need to enter the working area or approach moving components, the machine should first be placed in a safe condition according to the operating procedure.

3. Remove Debris and Foreign Objects

Inspect the car wash working area and remove stones, trash, loose objects or other debris that could interfere with machine operation.

Foreign objects inside the operating area may affect moving components or create unnecessary safety risks during the wash cycle.

4. Inspect the Brushes

Check the brushes carefully for foreign objects and confirm that the brush assemblies are in normal condition. Any trapped object should be removed before starting the machine.

Pay particular attention to the top brush and other areas where foreign objects may become caught. When approaching the brush area for inspection, follow the required safety procedure and use the emergency stop where necessary.

5. Check and Refill Consumables

Check the levels of the cleaning liquids and other consumables used by the car wash system. Refill them when necessary before beginning normal operation.

Maintaining sufficient consumable levels helps ensure that the corresponding washing functions operate correctly throughout the complete wash cycle.

6. Check the Solenoid Valves

Inspect the solenoid valve area and related components to make sure they are working normally. Look for abnormal conditions that could affect water, air or cleaning-fluid delivery.

If any abnormal operation is found during inspection, it should be addressed before the machine enters normal service.

7. Check the QR Code and Network Connection

Confirm that the payment or QR-code function can be accessed normally and check that the machine has a stable network connection.

A network test before opening for daily operation can help identify connection issues before customers begin using the system.

8. Run a Complete Wash-Cycle Test

After completing the daily inspection, perform a test wash to confirm that the major washing functions operate normally.

During the test cycle, pay attention to key functions including:

• Foam application
• Brush operation
• Water spraying and rinsing
• Coating or related liquid application
• Air drying
• Overall machine movement and sequence

Observe the complete process and check for unusual movement, abnormal sound, interrupted operation or other issues. The machine should only enter normal service after the test cycle is completed successfully.
