Hi,
does anyone have a user manual for an old karcher HDS 500 ci.
also which diesel does it use, heating oil, red diesel or regular car diesel from the pump.
This is a pressure washer that has an electric motor for the pump and a diesel/oil burner to heat the water

Not sure what the 'o.eltro' means? There is help in the link and the service manual for a different series of HDS washers. You could also contact Karcher direct.
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.
hi could you post your email address and i can email you a full pdf file, also on the chassis of the machine there will be a silver sticker could do with all the numbers to find which modle it is regards
Hi Jim,i have the same unit to,can you tell me are you connecting to mains water via the small black header tank at the back next to the boiler or is it connected straight to the pump head inlet?
Theres more than one reason i'll just start with this one 1st.

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 solenoidvalve, (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 [email protected] Cheers Matt.
