What to do if Kärcher K 5.68 M output pressure varies high and low?
If the output pressure of your Kärcher Pressure Washer varies, ensure that the water is turned on full force and check the garden hose for any kinks, leaks, or blockages that may be restricting water supply. Another possible cause is that the pump is sucking air. To resolve this, check that all hoses and fittings are airtight. Turn off the machine and purge the pump by squeezing the trigger gun until a steady flow of water emerges through the nozzle. Also, the water inlet filter may be clogged, remove it and rinse in warm water. Lastly, the discharge nozzle could be obstructed, blow it out or remove any debris with a fine needle. A calcified gun, hose, or spray wand can also cause this issue; if this is the case, run distilled vinegar through the detergent suction tube.
Why Kärcher K 5.68 M Pressure Washer unit does not reach high pressure?
If your Kärcher Pressure Washer isn't reaching high pressure, there are several potential causes. The diameter of your garden hose might be too small; replace it with a 5/8 inch or larger hose. Check the garden hose for kinks, leaks, or blockages that could be restricting the water supply. Ensure that you have enough inlet water supply by opening the water source fully. Also, the water inlet filter may be clogged, remove the filter and rinse it out in warm water. Lastly, make sure the spray wand is set to the high pressure position.
Why is there no detergent coming out of my Kärcher K 5.68 M?
If your Kärcher Pressure Washer is not dispensing detergent, first check that the detergent suction tube is properly connected to the machine. If the detergent is too thick, dilute it; for optimal results, use Kärcher® detergent. A clogged filter on the detergent suction tube can also be the cause; run warm water through it to remove any debris. Inspect the detergent suction tube for damage or clogs; remove any obstructions or replace the tube if necessary. Ensure that the spray wand is in the low pressure position. Finally, check the discharge nozzle for obstructions and blow out or remove debris with a fine needle.
