The K365M model high pressure washer from Karcher is an electric unit that is plugged into a standard electrical socket. When the washer is not working correctly, you'll need to troubleshoot the unit to fix the problem. Problems can include the motor not starting and the unit not reaching sufficient pressure when washing.
Motor fails to start
Verify that the power switch for the unit is in the "On" position. This is basic, but sometimes easy to forget when you're in a hurry.
Check the power cable and see if it has been plugged into a power socket or has become disconnected, particularly if you're using an extension cable. Plug the power cord into the electrical socket and then turn the unit back on.
Measure the length of the extension cable that you are using with a tape measure. If the length is greater than 8 metres the power washer may not receive enough electricity to start.
Check to see if a breaker has tripped or a fuse has blown on the circuit panel. Reset the breaker or replace the fuse and then turn the unit on to see if the motor will start.
Check that the diameter of the garden hose you are using is at least 1.75 cm. The power washer will not get enough water if a smaller diameter hose is used.
Examine the garden hose to see if there are any kinks that can restrict water flow. Remove the kinks from the hose and see if the water pressure increases.
Check the tap that you are using and make sure that the valve is open all of the way. Turn the tap to fully open the valve.
Remove the inlet filter from the pressure washer and see if it is dirty or clogged. Rinse the filter with warm water to remove any debris and then place it back in the unit.
