Little or no spark from my karcher 551c hds

It will be like this, HDS Compact Series. Page 27. They are unmistakable, a silver aluminium can with wires coming out of the end.

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.

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 i have a archer has 601 with problems. the boilers not igniting properly and I'm getting a roaring noise and thick white smoke. the fuel sides working fine iv changed the igniter and the coil still the same works when it wants to. any ideas thanks

Hello, first how many miles do you have on this Lincoln? On that 4.6 L V8 engine they do have spark plugs but each plug has it's own spark coil located on a long rubber plug. You will see four little coils on each side of the engine. There will wires going in to the individual coils. There will be a bracket the holds the coils in place with a small 9 or 10 mm nut. Remove the nut, and gently pull on eac coil. There Hello, first how many miles do you have on this Lincoln? If you have over 120 thousand miles on this engine then it might need new spark plugs. On that 4.6 L V8 engine they do have spark plugs but each plug has it's own spark plug coil. You will see four little coils on each side of the engine. There will wires going in to the individual coils. There will be a bracket the holds the coils in place with a small 9 or 10 mm nut. Remove the nut, and gently pull on each coil. There a long rubber plug that fit in each spark hole. These rubber plugs are about 4 1/2 to 5 inches long.


Before removing the plug use an air hose with 50 to 60 lbs of pressure to blow each spark plug hole out which might have foreign object in the hole. Why, if you remove the spark plugs, and there is foreign material in that plug hole. Guess what, that stuff will fall into the combustion camber.



Then you will really have some problem. How fix if stuff fall into the combustion camber.

Squirt small amount of oil in the combustion camber, unplug all the coils and clear out there plug hole. Now remove all the spark plugs. Now, you can crank the engine and will the little amount in that cylinder that has the junk in it. The oil will wet the foreign debrie, and blow it out the spark plug hole. Then use a clean rag with with some oil it with a long screw driver to clean that spark plug hole Be careful that don't push the foreign material back into the combustion camber. Do this several time with little amount of oil.



Now, you can install the new spark plugs. On the spark plugs threads use some anti-shiz grease. Why squirt oil into the combustion camber? The oil is used to seal the rings on the piston to increase the cylinder compression. Just a small amount goes a long ways. GB...stewbison

Placing 2 cycle gas into a 4 cycle engine does not cause problems (but will blow white smoke and, in time, dirty the plug). I would have probably just ran it through.
:o).

the air fuel mix is not correct. the coil is blocking the air intake. fuel nozzle not pointing into the combustion chamber?
