High Pressure Washer Maintenance Tips to Make Your Lenhard 2850A Last Longer

A High Pressure Washer is one of the most important machines for any car wash, garage, or home cleaning setup. And if you’re using the Lenhard 2850A, you already know how powerful it is — 195 Bar pressure, 2850 PSI, and a water flow of 14L/min.

To keep this machine running at full power and extend its lifespan, proper maintenance is very important. Below are simple, practical tips to help you take care of your High Pressure Washer and get the best performance every day.

1. Always Use Clean Water

Your Lenhard 2850A needs clean water to avoid clogging the pump and damaging internal parts.

✔️ Use a clean water source

✔️ Check the inlet filter regularly

✔️ Avoid dirty tanks or water with soil/sand

Dirty water is the number one cause of pump wear.

2. Check and Clean the Water Filter Frequently

The water inlet filter stops debris from entering the machine.
When it’s dirty, the washer is forced to work harder, reducing power and causing overheating.

Maintenance tip:

Remove the filter → rinse with clean water → fix it back.

Do this every day if you run a busy car wash.

3. Inspect the Hose and Connections

The high-pressure hose handles strong water pressure. Small leaks can reduce power and damage the pump.

Check for:

Cuts
Leaks
Loose connectors
Worn-out seals

A simple inspection can prevent costly breakdowns.

4. Bleed Out Air Before Starting

If air is trapped inside the pump, it reduces pressure and strains the motor.

How to remove air:

Connect water
Open the trigger without powering the machine
Let water flow until all bubbles stop
Then turn on the machine

This ensures full pressure and protects the pump.

5. Avoid Running the Machine Without Water

Never start the Lenhard 2850A without water flowing through it.

Running dry can:

Damage the pump
Overheat the motor
Reduce lifespan

Always confirm water is running before switching on.

6. Don’t Run the Pressure Washer for Too Long Continuously

Give the machine a break.

If you are doing car wash back-to-back:

Use for 20–30 minutes
Rest for 5–10 minutes

This keeps the pump cool and prevents overheating.

7. Use the Right Nozzle for the Right Job

Your High Pressure Washer has different nozzle options. Using the wrong one increases strain.

Example:

Wide-angle nozzle: general car washing
Narrow-angle nozzle: tough dirt, rims, engines

Switching correctly helps the machine work efficiently.

8. Store the Machine Properly After Use

Good storage increases lifespan.

After washing:

✔️ Turn off the machine
✔️ Release pressure from the gun
✔️ Disconnect hose and power
✔️ Store in a cool, dry place
✔️ Avoid direct sunlight or rain

This prevents rust, corrosion, and electrical damage.

9. Protect the Pump With Regular Lubrication & Servicing

Even though the Lenhard 2850A is built to last, the internal pump needs care.

At least once every few months:

Check oil level (if it has an oil pump design)
Replace worn seals
Tighten vibrations points
Service or clean the pump head

A small service routine prevents big problems.

10. Use a Stabilized Power Source

Sudden power changes can burn the motor.

Best practice:

Use a quality extension cable
Avoid weak power outlets
Use a voltage stabilizer if possible

This protects the motor and increases reliability.

Final Thoughts

A High Pressure Washer is an investment, especially for car wash businesses. Taking care of your Lenhard 2850A with these simple maintenance tips ensures strong pressure, faster cleaning, and a longer lifespan.
