Tips To Repair The Karcher Pressure Washer Hose

Below are the tips you must keep in mind as you repair the Karcher pressure washer hose.


#1. Run water in the machine

If there is sticking in the bypass valves, pulsing, and an air block, get the machine disconnected from the electricity supply. Get the black high-pressure hose removed and connect it to a garden hose with a free flow connector. Perform this before turning on an outside tap and leaving the water so it runs through five minutes. Reconnect the hose/black hose and click the gun trigger, drawing moisture to the hose, into the jet pipe and the gun.


#2. Store the device properly to prepare for the winter season

Store the pressure washer correctly to avoid frost damage later on. Detach accessories before you put the device away and tip water away that it contains and drain the pressure washer to prevent frost damage. Click on the trigger gun and observe until the water doesn’t flow out of the machine. Next, store the device in a safe environment, free from frosting. Expect that it will work perfectly in the spring season.


#3. Check the garden hose to be fully uncoiled

The pressure washer pulses are more in use due to a blockage in the accessories you use, so try to soak the accessories in soapy and warm water before rinsing them off completely.


#4. Check its extension cable if the pressure washer cuts out

If the pressure washer cuts out unexpectedly, it’s because you are using an extension cable. Ensure the line is thirteen amperes in constant rating and is not longer than thirteen meters.


#5. Check if the water flow is sufficient

The pressure washer vibrates more than the ordinary if its water flow is too low. One to four series machines use like six liters for every minute. With five to seven series machines, they utilize nine liters every minute, turn the garden tap on first and uncoil the garden hose completely.


#6. Check the hose in a pressure washer if it loses pressure

The problem is a leak, blockage, and kink in the hose is because of pressure loss in the machine. Check first if the water is total and check the amount of water to supply, as in the manual as the issue is due to the debris found in the nozzles, trigger gun, and water inlet filter, so clean them out and wonder if this solves the problem.


Common Problems To Repair In A Karcher Pressure Washer Hose

Below are the common problems to repair in a Karcher pressure washer hose.


#1. Vibration

The pressure washer vibrating is due to an insufficient flow of water. Check the outdoor tap, and it should be fully open to ensure there will be no leaks or kinks in the garden hose. It could be due to a small size in the hose diameter. Better yet, replace a three-fourth inch hose in a garden hose and solve this issue immediately following this advice.


#2. No water in the lance

If you click the trigger while the lance has no water spray produced, it could block its tip. Use wire clips to remove debris or dirt. Avoid lance from dropping on the floor if not used. Return it to the storage slot if done with using it.


#3. Inconsistency in the pressure

Inconsistency in the pressure is due to the improper calibration of the unloader valve. Check the instruction manual while you adjust the unloader valve calibration.


#4. Detergent not available

If there is enough detergent available in a bottle, but none comes through, it’s due to many things. Make sure you connect the detergent suction type correctly and try to dilute the detergent with water if it is too thick and observe if it makes a big difference. Afterward, check to clean the filter in a suction tube and set the spray in low pressure.


#5. Leakage

Secure the connections in the pressure hose, garden hose, & spray gun. If there are still leaks, replace the washer even if you have already secured it. If water leaks in a water pump, check if you tighten the fittings and if it continues leaking, call for some servicing.
