Hi. Water flow may be restricted to the pressure washer.

Check that all hoses are free of kinks, leaks, or blockage. Make certain all hoses and fittings are connected properly. Make sure to open the faucet/spigot to full force. Set the spray wand to high pressure.

Clear any debris from the nozzle. If the nozzle has even a little bit of dirt in the tip, it may cause enough obstruction for the pressure washer to pulsate. If your pressure washer came with a nozzle cleaner, use it to clean the tip. If not, you can use a pin or paper clip to clear the nozzle tip of debris that may have become lodged in it.

If these have been checked and the washer is still fluctuating from high to low pressure there may be air trapped in the pump. To bleed the pump of any air, turn the machine off and disconnect the high pressure hose and trigger gun from your power washer. With only the garden hose connected to the machine, turn on your water source and allow water to run through the pump of the machine for 20 or 30 seconds. Turn off the water and connect the high pressure hose and trigger gun and try using the machine again.
That is sure signal of insufficient water supply!

try easy solution first:
make sure that your mains is fully open, that tap on whihc hose is hook up is fully open and hose is of "decent" diameter to allow sufficient flow.

if above solution do not work then you need to make another, more difficult arrangement:
prepare 20litres pressure tank with inlet connected to mains and outlet by short hose to power washer, fill it with water from mains, keep it under mains pressure and use karcher power washer normaly. this will solve water supply problem. twenty litres will last about 2min, because it is re-filled, under standard pressure therefore it will last about 3min...

third possibility is to stop washing...
