Karcher Replacement Parts for Pressure Washers

Karcher pressure washers are recognized worldwide as some of the toughest, most dependable power cleaning machines in the industry. Like with other high-quality equipment, Karcher pressure washer owners should be ready to maintain and service their machines when necessary.
Pressure washers are complicated, water compressing machines and diagnosing them can be a little tricky.
One of the most common pressure washer symptoms is low water pressure (or no pressure). Low pressure symptoms can even present when the washer’s motor seems to be running fine.
Common Causes of Low Pressure in Pressure Washers
1. Lack of power to the machine.
Even if your Karcher pressure washer is running, it may not be receiving the necessary power to produce high water pressure.
* If your pressure washer is electric, compare the power it is receiving from its outlet to the pressure washer’s power specifications in your owner’s manual.
Make sure you’re running your electric pressure washer on an outlet that provides enough power.
* If your pressure washer is gas-powered, a variety of engine tune-up items might be the cause of low pressure.
Replace filters, spark plugs, and belts if necessary.
Check the engine’s oil level and change the oil if it’s been a while between changes.
2. Low or incorrect water supply.
* Check your washer’s GPM rating in your owner’s manual.
The GPM rating indicates the gallons of water per minute that your washer needs to operate at full pressure.
* Make sure that the water supply is the correct temperature for your pressure washer model. Only run hot water through pressure washer models designed for hot water use.
3. Leaks and/or obstructions in the out-going water line.
Any leak or obstruction along the water path in your pressure washer can cause it to operate at a lower pressure.
Start at the nozzle end of the pressure washer and work your way back to the motor. Check the following parts for dirt build-up, cracks, damage, and wear.
* the nozzle
* the washer wand/gun
* hoses
Clean the nozzle and washer wand if they’re dirty. Pressure washer nozzle cleaning tools are even available to help with this.
Check the nozzle, gun, and hoses for cracks and other signs of heavy wear. If any of the above parts are worn or damaged, they will have to be replaced in order to return pressure to your Karcher pressure washer.
4. Mismatched pressure washer parts.
When replacing wands, filters, nozzles, hoses and other Karcher pressure washer parts, only use Original Equipment Manufacturer parts that correspond exactly to you pressure washer’s model.
Any mismatched part in any area of the pressure washer can cause it to lose pressure.
