Hi from retired Englishman in SW France,

(check all of these things but for 'cold' only!)

If you have checked that the hot and cold water taps are turned on fully and the hoses are not kinked or squashed at the back, it is worth while checking both the hot and cold water inlet filters. Turn the taps off and remove both hoses at the washer end. Inside each inlet port there is normally a little filter which should just slide out. Clean if necessary and replace each one and the hoses. If after turning the taps back on there is no improvement, the problem is symptomatic of a malfunctioning hot or cold water control valve. Sorry but it needs a service call and a check that it isn't the control PCB ;-0(

If this has assisted you please consider a 4 thumbs up for the rating.
Thanks and good luck,
John C

karcher K3.97 MB when connected up to tap and switched on pressure poor and motor seems slow cleaned hose end, and filter looks clean

It sounds like the fuel bowl is not filling quickly enough. Turn the fuel tap off. Then take the fuel bowl off the carby. You will see a plastic float. Above the float is a needle (small pin like) that should shut the fuel off & let it run also. Turn the fuel back on,the fuel should be running out quickly. Push the float up and the fuel should stop running. If no fuel is coming out then the needle is stuck. Clean with carby cleaner and push up & dowm a few times to ensure it is working OK. You may need to replace needle. Turn fuel off. Put fuel bowl back on and turn fuel tap on. Test.

Normally when you dry run a machine you damage the pump so it would probably need changing. The motor might be Ok but for you to fix it you will need to take it to a Karcher dealer/service center.

From experiance it sometimes can be more cost efficient to purchase a new Karcher machine and get the 12 month warranty than spending money on an older machine.

The lance hose that attaches to the pressure washer keeps coming off when the power to the machine is turned on, i've only used this product four times since new in January this year.

Yes, the water should be turned on first but if it only ran for a minute or two it should be OK. Most late model pressure washers have an automatic shutoff when the trigger on the wand is released. Turn on the water and then the machine and then squeeze the trigger on the handle of the wand and the motor should start as soon as the air is cleared from the line by the flowing water (about 10 seconds). If the unit was put away wet last season you may need to clean the nozzle with a piece of wire too.

You have an air lock in the pump and or piping.

• Open all drain cocks and remove the spray hose
• Connect the inlet water hose and turn it on slow
• allow water to run from all open ports for 2 minutes or so
• leave the water running - close drains start motor
• Shut down reconnect spray hose restart
• You should now be smiling
  

hi,
there is a small ball bearing inside the nozzle on the end of the lance , this can get jammed or missaligned and the nozzle orifice can get blocked , clean this or replace the whole lance with another 200 Bar lance .

hope this helps

Brother Art,

Try this trick; it always works for me. Assemble the garden hose to the washer, install the HP hose, turn on the water. Now, make sure that there is no air trapped in the garden hose. Manipulate so as to direct any air trapped in the line to the washer. Connect the gun and continue to allow water to "free flow" for several minutes. Now, work the trigger, allowing the unit to rise to "house pressure, and then pull the trigger, dropping the pressure suddenly. This displaces any air hidden in the system. Do this several times, and start the washer up. If this doesn't get you up to pressure, repeat the above on an abbreviated scale, and hold the trigger on the gun down while you start the washer. This should do it.
