If you’re using a fully automatic car wash machine and encounter problems, don’t panic. This guide will help you troubleshoot and resolve common issues efficiently.

1. Why Does Car Wash Machine Oil Turn White?

The whitening of car wash machine oil is typically due to the expiration of the oil seal’s service life, leading to damage and water leakage. After replacing the water seal, if the problem reoccurs within half a month to a month, the piston may need replacement.

2. Why Won’t the Fully Automatic Car Wash Machine Start?

– Check if the starting capacitor is damaged. If so, replace it.

– Ensure the circuit is powered.

– Verify if the fan is rotating. If not, check if the pump head is locked. Depending on the damage extent, replace or repair it.

3. Why Isn’t the Water Gun Producing Water?

Scale buildup in the water tank may block the water nozzle during operation. Disassemble the water gun nozzle, turn on the water gun to flush out scale from the water pipes, and then rinse the nozzle with clean water before reinstalling.

4. Why Is There a Strange Noise from the Self-Service Car Wash Machine Pump Head?

Check if the pump head is overheating. Overheating can cause tile bursting. To prevent this, maintain and lubricate the pump head regularly.

5. What Causes Low Water Gun Pressure?

– Inspect the inlet pipe for leaks. If leaking, replace the inlet pipe.

– Check the return pipe for leaks. If leaking, replace the return pipe.

– Verify the pressure regulator’s settings. If there’s no indication, replace the regulator.

– Ensure the water gun nozzle isn’t clogged. If clogged, replace the water gun head.

6. Why Is the Computer Car Wash Machine Motor Overheating?

Avoid using the machine continuously for more than 1 hour. If usage exceeds the normal time, stop and let it cool for about 10-20 minutes. Overheating can cause gas bursts, severely damaging the motor. Check the power supply promptly.

7. How Often Should Gas Station Car Wash Machine Oil Be Changed?

Oil change frequency depends on the car wash volume. Generally, change the oil monthly, assuming an average of 30 cars per day. For daily maintenance, use different oils for winter and summer—less oil in winter and higher viscosity in summer. Do not use diesel engine oil, gear oil, or used engine oil before changing the oil.

8. Why Does Car Wash Machine Oil Turn Gray or Black?

Prolonged use of the car wash machine can lead to internal wear and abnormal noises. Disassemble and inspect the connecting rod and bearings under the crankshaft (using professional tools). This indicates the equipment requires repair.

9. What Causes the Intelligent Car Wash Machine to Shake?

First, check the screws connecting the motor and pump head. If loose, tighten them. If the shaking persists, it may indicate keyway damage over time, necessitating new parts.
