My karcher isn't giving me hot water why? It's a hds 601c


Morning Chris Taylor,

You have an igniter/burner coil inside your system that has to be
functioning properly to have good combustion going inside the coils of your heater unit (very bottom).

I tried to pull the documents to see if yours was kerosene powered (like mine: not a Karcher)... but could NOT pull your HDS 601C up on the company site (Karcher.com, sorry... It's me & my new PC).

Poor water = de-lime water coil procedure

Cool water = No combustion, check kerosene, oil (burner fuel)... filter... (etc.) and check your spark!

If your air supply is insufficient to support great combustion your ignitor & fuel nozzles can get heavily built up in soot. My manual says to clean it with detergent & water... I have only ever used Berryman choke & throttle body cleaner.

All the precautions... don't hurt yourself!!

Hope this helps...

Hi,karcher hds hot pressure washer now pressure when you pull trigger and pulses.


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.

Karcher 2500 no pressure problem


sounds like you have an inlet blockage to the pump or not enough volume to feed the pump. make sure hose is turned full on when washing and see what happens. if not you may have to remove adapter wher hose screws in and check for a blockage.

Karcher HDS 750 HOT HIGH PRESSURE WASHER


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.

my e-mail is cgodfx@internode.on.net

Cheers Matt.
