Troubleshooting a DeWalt DH3028 pressure washer involves several steps to identify and resolve common issues. Here’s a systematic approach:

### 1. **Safety First**
– Ensure the power supply is disconnected or the gas supply is turned off before performing any checks.

### 2. **Check the Power Supply (for Electric Models)**
– Ensure the power cord is securely connected and not damaged.
– Verify that the outlet is functioning by testing it with another device.
– Check the reset button on the pressure washer if it has one.

### 3. **Inspect the Fuel System (for Gas Models)**
– Ensure there is enough fuel in the tank.
– Check the fuel line for any leaks or blockages.
– Replace the fuel if it’s old or contaminated.

### 4. **Examine the Water Supply**
– Confirm that the water supply is turned on and that there is sufficient water flow.
– Check the inlet filter/strainer for debris and clean it if necessary.
– Ensure hoses are not kinked or damaged.

### 5. **Inspect the Hose and Nozzle**
– Check for leaks or blockages in the spray hose.
– Inspect the nozzle for clogs and clean it with a pin or needle if necessary.

### 6. **Test the Pressure Washer**
– Turn the pressure washer on and let it run without the nozzle attached for a moment to see if water flows properly from the pump.
– Reattach the nozzle and test the pressure. If it’s low, the nozzle may still be clogged or there could be an issue with the pump.

### 7. **Look for Leaks and Sounds**
– Inspect for any visible leaks around the pump and connections.
– Listen for unusual sounds, which could indicate mechanical issues or the need for lubrication.

### 8. **Check the Pump**
– If there’s no water flow or pressure, the pump may be damaged. Look for signs of wear or damage.
– Check the pump oil level if applicable and change it if it’s dirty or low.

### 9. **Evaluate the Thermal Relief Valve**
– If the machine shuts off unexpectedly, the thermal relief valve may be engaged due to overheating. Allow the machine to cool down and check for blockages.

### 10. **Electrical Components**
– Inspect any electrical components, such as switches and connectors, for signs of damage or corrosion.

### 11. **Consult the Manual**
– Refer to the specific user manual for troubleshooting specific error codes or issues that may not be covered above.

### 12. **Professional Help**
– If the issue persists after following these steps, it may be time to consult a professional technician or take the unit to a service center.

By following these troubleshooting steps, you can identify common issues with the DeWalt DH3028 pressure washer and determine the necessary adjustments or repairs.
