Karcher 256 Pressure Washer

[codswallop]

I have had the above unit for several years but seldom used mainly because there is a bad leak from the front of it also when all systems are go and the trigger isn't depressed the motor keeps "shunting" Because of the amount of water leakage it's difficult to determine where the leak is coming from.Can someone suggest what and where the likely cause is please? Thanks

A common place to leak is the inlet and outlet couplings .. the 'O' rings may need replacing.

Hi, You will most likely find the leak coming from either the Inlet water flow or the out let water flow, it's very easy to sort but you do need the screwdrivers for the job, on the yellow plastic front cover there should be 8 deep screws within the body, they are TORX SCREWS so you need a set of these type of drivers, take the front cover off, re-join the water inlet & turn on your water very slowly, you willthen see the cause of your problem, to find spares & they are very cheap in price, Type in Espares in Google, you will have the spares within a week, if you take the old part off, make sure you get the part Number which is on the body of the pipe ( That I think & is usualy the cause of the problem) you can do this job in under an hour.

Hi CW, there is another possibility?
If you have had the washer for a number of years then it is quite possible that the washer was stored in a garage or outer building with water still in the pump which froze solid during the winter and it split the internal pump, which, years ago were made of plastic. I think later ones are possibly made of steel because of the possibility of freezing.
The motor will keep working if the pump is leaking due to a reducing pressure in the pump.
You could check for replacement parts but whether a metal pump will fit the same as a plastic one????? You will have to ask the supplier.
