Vibrating Pressure Washer

If performing the actions above didn’t cure your pressure washer from vibrating. The problem could be caused through insufficient water flow. Check your outdoor tap is fully open and that the garden hose has no kinks or leaks.Another reason for the pressure washer vibrating could be the hose diameter is too small. Replace the garden hose with a ¾ inch hose, this should solve the problem.

Pressure Washer Pulsating

If your pressure washer is pulsating while on standby,check the water supply. If the tap is not fully open or the garden hose is kinked or leaking, this can cause the machine to pulsate.

If the pressure washer is pulsating while in operation, it is usually caused by a blockage in the nozzle or accessory. If it is the nozzle, use the tool provided by Karcher, or fashion one from a paper clip by opening one end. Simply push the wire into the nozzle and wriggle it about to dislodge any blockage, then pull the trigger to release the dirt from the nozzle.

The Pressure Washer Cuts Out Whilst Inuse

If your pressure washer cuts out while you are using it, it’s probably an electrical fault.
