Question and Answers

Q:

Pressure washer pump oil leak when unbolting 4 front bolts. K2400HH Pressure washer

A:

Thank you for your inquiry on your Karcher Pressure Washer, Model: K2400HH. From reviewing the details on your model, Sometimes the pump body material is damaged when the bolt is removed. Because of this, the hole will continue to leak no matter what type of plug is inserted into it. You can try using some Teflon tape around the brass bolt to seal up the hole. If that does not work, you may need to try some liquid Teflon pipe sealer to remedy this problem. If that does not work then you'll most likely need to have the hole re-threaded to a larger size and then increase the size of the bolt to match it. In the event I would recommend replacing the pump. If you purchased the oil for the pump from Parts Direct it is a pre-measured amount and you would put the whole bottle in. If you purchased some aftermarket bulk oil for pressure washers, fill the pump to within a 1/2 inch from the cap. That 1/2 inch will allow for expansion of the oil when it gets hot during operation.

Safety Warning: Before beginning the repair, disconnect the direct power supply to the pressure washer to prevent the risk of injury or any electrical shock.

If you don’t feel comfortable or confident in this repair, then you can have it repaired at home by a sears technician. I have the included a link to the website: Sears Home Services or call 1-800-469-4663.

I hope this answered your question. Thank you for contacting SearsPartsDirect.com, and have yourself a wonderful day.

A:

Thank you Jerome for providing the link to the Owners Manual. I was also provided the link to the various parts in the assembly situation. However the parts diagram does not show the carberator or the ignition section. I have determined two things. A) There is no sspark going to the plug. B) There is a clear plastic tube coming out of the bottom of the carberator and not going to anything. Don't know if it's a drain tube or has been disconnected from another section. Since I don't have the parts break-down to the carberator section, I'm at a loss as to what the tube does. Any ideas?

Q:

power washer problem

A:

Be certain that there are not water leaks in the water hose or supply or it will act like it's doing.

When the pressure varies here are some common causes:

  1. Not enough inlet water supply: *Turn water on full force. Check garden hose for kinks, leaks or blockage.
  2. Pump is sucking air: *Check that hoses and fittings are air tight. Turn off machine and purge pump by squeezing trigger gun until a steady flow of water emerges through the nozzle.
  3. Water inlet filter is clogged: *Remove filter and rinse out in warm water.
  4. Discharge nozzle is obstructed: *Blow out or remove debris with a fine needle.
  5. Calcified gun, hose or spray wand: *Run distilled vinegar through detergent suction tube.
If this tips do not help, I recommend taking the pressure washer in for servicing. NOTE: I do not recommend taking the pump apart.
