Check for any kinks or blockages in your hose. If there are none, detach the hose from the inlet valve on the washer and check to see if the water output is sufficient and that there is no debris caught in the inlet filter screen that may be restricting the flow of water into the washer.
PLEASE NOTE: You should always press the RESET button on the GFCI before using the pressure washer.
How Do I Tell If My Unloader Valve is Bad? In most occurrences, the first symptom of an unloader valve going bad is no pressure from the wand when the trigger is pressed. This happens when the unloader valve gets stuck open and does not allow water to enter the hose and trigger.
Yes, you can use a pressure washer gun with a hose. You will need to purchase a pressure washer gun that has the proper fittings to connect to your garden hose. Make sure that the pressure washer gun is rated for the PSI of your garden hose. Most pressure washer guns have a maximum PSI rating of 400.
STEP 1: Turn off your water supply at the mains. STEP 2: Turn on every tap in the house, starting at the top and working your way downstairs. STEP 3: Wait for the water to stop flowing out of the taps. STEP 4: Now flush all the toilets until no water is left there either.
Over time, the water circulating inside the pump gets hot. If the operator leaves the pressure washer running for an extended period of time without activating the trigger, a thermal release valve will open and discharge the heated water so cooler water can enter the pump.

Why dose my Karcher K2.35 keep blowing the gun hose off?
ANSWER : There is a good chance you are missing the black plastic clip that holds the hose into the trigger gun. If you look at where the hose goes into the gun there should be a flat slot where a black plastic clip would slide in and keep the hose into the trigger gun.
