G-day Mate.

Did you check if the igniters? they may be cloged up with ****. Unscrew the Sight glass on top of the boiler and run the machine (in cold or hot mode, doesn't matter, as the igniters are running all the time) and see if there are working, you should take them out anyway and give them a wipe with a rag as general maintenance item, and when you put them back in there should be about 5mm gap between them.


Less common reasons for the boiler to not work
- Faulty fuel solenoid valve, (You should hear a click sound about 5 - 10 seconds after you pull the trigger)
- Dirty fuel filter,


Take a look at those simple things and let me know if its any of these.

I have a Karcher HDS 750 1989 Year model

This machine just keeps going, it's had a fairly tough life but it has stood up to it all,

i hadent spent anything on it until about 6 months ago when i purchased a new fuel pump for it as the old was wasn't pushing 170PSI to the Disiel injector it had slowly droped 70psi, and it doesn't create a hotter burn in the boiler, but still very good for a 19yr old pump,

other than that thats all it's needed, it's still going strong to date
Very robust machine.

Cheers Matt.

Well, there is a switch inside. It is controlled by the valve that allows the pump to go into bypass when you let go of the trigger. This switch may be worn out or the valve that controls it is sticking. It may also be that your motor is just worn out. There is a heat sensor inside the motor (you cannot get to it) that sometimes wears out and trips too easily.

what you need to do is, take the screw fitting which goes to the water tank off, then the one that goes from the water tank to the pump head .
then put the one that was in the first place going to the water tank on to the pump and force feed with water.
see if you can see water leaking from any where seals hose.
try running the machine to check the pressure.
if water leaking from pump head you need seals.
