Question: Drain Plug

1207988

I need to change the valves (part 4.580-330.0) on my Karcher G2400HB. I would also like to inspect the other 3 valves under the brass plate, however am unable to remove the "drain plugs". Any ideas on how to remove? At $9 apiece I sure don't want to damage one.

Question: Karcher Not Spraying

AJMilheiro

Hi. I have a Karcher K2400 power washer (301.0) model and once I start it, it sprays the first time, but when I release and press the wand again, it does not spray.

I heard it may be the unloader valve that needs replaced. Before I order that part, I was wondering if there may be any other parts that may be causing this not to spray?

Thank you
Armando

Question: Karcher Hh2400 Pump Leaking

1189527

Hello to all,
I have a karcher hh2400 with the 5hp honda engine, just like the one in the repair video. My question is after rebuilding the pump just like the video it leaks a little water out of the pump. The leak is a constant stream, seems to be coming from the in between the brass plate and the base plate that attaches to oil reservoir. Any help would be greatly appreciated.
Have K 2400 HH- 1194-301.4 Replaced gun, with 9112-0140 replacement. Sprays a few minutes then engine stalls. If I release the trigger engine starts running ok. Pull trigger... stalls. Was working fine before new gun install.New Gun rated @ 3000psi & 6.6gpm. Any help appreciated.

What type of oil do you use in the pump and what is the filling procedure.

Question: Pump Oil

hayeslar

how much oil is required in the pump, (not motor) and how is it filled?
what would cause this? would the O-Rings from the spill valve and thermal release valve o-ring? or would the spill valve be bad because i did have the preasure come and go last fall before i parked it for the winter.

Question: Teflon Grease

SSmith

I'm having problems finding Teflon grease here locally. I was able to pickup "Magic Lube" at the local Pool Supple store.

They claim they stopped caring the Teflon grease a few years back claiming this was better?

They said that this was silicone base and designed for o-Ring and seals. The tube states that it's a PTFE based.

Will this work on the spill valve?

Note: I found that the easy way to remove the spill valve is to place a rag over the opening and hooking up the water house and sprayer to the pump.

Then just place your hand over the rag and turn on the water. Pop out right into my hand without have to use needle noise .

Question: Rebuild Or Replace?

madog6862

First where do I locate Vidio # 2, on replace spill valve? Cost wise which is better, rebuild pump or buy new one. Is there a complete rebuild kit with all valves, springs etc including Spill parts, which Part #. I understand a new pump cost around $250.00, if that's so wouldn't it be better to buy a complete new pressure washer, maybe upgrading to 3000 psi??
I cleaned the pump and replaced the spill valve. The pump works as expected at engine idle speed (Not so much pressure). When I "give it the gas" and bring the engine up to power, the pump pulses. Suggestions?

Question: Fix Pump Or Get New

I have a K2400HH Karcher pump. I have it taken apart and upon inspection, there is a lot of calcium built up on the parts and casings. I especialy had difficulty getting the spill valve out. My concern is the calcium in the bottom of the piston guidance housing and the "scratches I made in the top of the housing in getting the spill valve out. Spill valve $12, housing $55, Repair kit $99. Looks like at $193 a complete pump is a better option. Note: pump is about ten years old with no use the last 5 years. Motor works great. Pump is the problem. Intermittent to no water pressure. Thank you. PS Video to repair pump was great!

I would try fixing it. Give it a good cleaning and replace the unloader valve. Unless the scratches are really deep and extent beyond the upper o-ring on the unloader I don't think that they will effect the function of your pump. The small wire brushes from a gun cleaning kit work great to remove the calcium from the castings. Let us know how it works out for you.

Question: Oil ?

ggee5334

Is there a part 2 video to see what happens after you dis-assemble and clean. What type oil is used in the pump assembly? I have a water leak between the brass top housing and the cast middle housing. I'm not sure which seal will solve the water leak between the 2 body pieces. I planned on buying the kit (part number: 2.884-214.0) Will this solve this problem?

Reply: Spill Valve

Hi chavajimenez,

The spill valve is held in place by the lower O-ring and usually some calcium deposits. To remove the valve you grab the metal tab on the top of the valve with a good pair of needle node pliers. The pliers must have a good set of teeth on the jaws or they will simply slip off. Then the valve is pulled out of the housing.

We have a couple of videos that show a complete Karcher pressure washer pump rebuild. Parts of these videos cover the removal and installation of the spill valve.

The removal of the spill valve starts at the 6:00 min mark on this video...

The replacement of the spill valve is covered starting at the 3:47 min mark on this video...

Hi chavajimenez,

Karcher specifies using 15W40 non detergent oil in their pressure washer pumps. They do have their own oil that they recommend using. The oil is part #6.288-050.0

Hello, I was wondering if anyone knew what weight oil my power washer used for the engine not the pump. It has the original Honda engine but I don't have the paperwork so I am unsure of the specs. I was going to go with the traditional SAE30 but wanted to be sure.

Thanks,

Hi Alvin,

Most pressure washer issues concerning no pressure or intermittent pressure can be traced to the spill valve, item #12 on page D. I have seen the shaft in the valve broken in half before. Usually the valve is just very dirt or covered in scale. Replacing the valve should fix the problem. When the new valve is installed, the upper o-ring should be lubricated with some Teflon grease. Do not lubricate the lower o-ring or the valve will not stay seated properly.

I hope this helps!

I recently placed Order Number: 1685958. I just want to mention that the part arrived on a Saturday and that evening I had the part replaced in my pressure washer and back running before Sunday morning. Your detailed video on the "Replacement of the Spill Value" on the Karcher Pressure Washer was all that I needed to get the job done. Thanks for your step by step instructions. A satisfied customer.
