Having problems with your Karcher Pressure Washers ?

My karcher hds 745 is running but just won't build up pressure, this occurred after a really cold few weeks this winter and I hadn't put anti-freeze through the machine to winterize it. There's no water coming from the bottom of the machine when it's running as i've read that if the pump seals are faulty water will escape from the pump etc. The machine motor runs ok but no pressure is acheived on the gauge whatsoever. Any help would be appreciated. Thanks in advance Paul.

Hi ..I have an Excell gas pressure washer model no. Exwgv2121-3 with Faip 2100 psi 2 gpm vertical shaft pump..the problem is that there is water leaking from every weep hole at the bottom of the pump when running. Oddly enough,the pump still puts out significant pressure but less than it should due to the leaking water. What is the most likely cause of this?..is it the high pressure water seal(s)? If so,how do I repair it?

It appears that there is not enough water pressure through the sprayers to to wash food 'deposits' off the plates and dishes.We have well water and it has a some what high lime content so I suspact that there is some calcium / lime clogging in the machine. I thought of removing the pressure pump to see if that is clogged up but before doing this, have you any other sugestions(i.e run vinegar through the pump? ). The holes in the sprayer . rotating arms appear to be clean.The machine has been e

Karcher 6.85 replaced seals as they were worn out and passing water into the oil now when I turn it on motor runs turning water on water comes out of outlet (which is ok??) but does not pressurize with hose disconnected. My Bosch pressure cleaner passes water through but when pump is started it pressurizes. Is it bypassing? Thanks in advanced

Water pressure? I read somewhere that low pressure of the incoming water will make it so that the items on the top drawer will not be as clean. I don't see how this can be the case, as I thought that the way the washer worked was that the washer filled (at whatever speed) and then the machine itself pumped the water through the system at the appropriate pressure. Please clarify.


Mom...not true. The water fills the machine which then uses its own pump to spray the dishes with the water/detergent. If your dishes are not getting clean, use the recommended amount of detergent. Hard water will require a spot treatment like Jet ... KitchenAid KUDR01TJ Dishwasher

Good mroning after starting any program first the pump will run followed by water intake. After a while the machine stops and the light intake/drain starts blinking. Most of the time water will stay in the machine. After pressing the on/off bottom first switching the machine on again and starting a new program the machine pump start running emptying the water but than stops after a short water intake again.

I recently replaced the water seals, V-packing & all six check valves in a CW-3504-4MGH pump on a MiTM 3504 pressure washer that had very low pressure. Usually this would fix most pressure problems on most machines, but in this case it had little to no effect. I suspect that the unloaded is the culprit in this case, but since I have had little experience in repairing unloaders (let alone adjusting them). I would appreciate feedback from anyone that has experience in this area. Thanks

G851 SC Plus started to trip GFI plug. Called Miele and they said there was nothing wrong with the dishwasher and the GFI was faulty. Unplugged from GFI and plugged into regular plug and it worked for a few days. Eventually stopped running. How wrong Miele was, it had everything to do with the dishwasher and not the GFI. It was only warning me a problem was coming. Appliance man came out, noticed water in bottom pan and order new pump, said seal probably gone. Came back, replaced the pump, put d

Upper spray arm is not turning round even though water is coming through. We have checked the internal system for blockages and the machine is filling / draining as normal. When a full programme is run, many of the dishes, particularly on the top shelf, are dirty and many have hardly been touched by water. Could a pump or other part be faulty?


I found the problem to be neither blockages of the upper arm or roof spray arm or the upper basket arm hitting the the back of the dishwasher. the problem was that the pump inlet where the food scraps are macerated was blocked with all manner of gung ... Dishwashers

Asko dw20 pump keeps running even with door open and turned off... The machine got to the final cycle then the pump just keeps running and the glass icon (L2) keeps flashing. All the water is not evacuated from the washer. When I power off from the front the drain pump still runs (and water is still not draining). When I power cycle from the mains (waiting 10 seconds) the pump engages again and the water level drops a bit and then stops draining. I have done this until all the water is empty an

No water pressure coming out while ingine is running. hoses/ attachments not clog. Pulled and opened pump, didn't see anything broken although noticed pump was filled with oil/lubricant but about 1/4" below top surface. Is it suppose to be filled to the top? What kind of oil is used on the pump? And how come there's no water pressure coming out while the motor is running and handle trigger engaged?

Troy-Bilt 2550 20293 pressure washer not producing pressure. Worked when last used 2 months ago. Pump pistons are moving up and down when engine is pulled through. Inlet water is flowing through pump but no pressure when engine is started. I have the same problem. Water flows thru the pump when not running, but no flow or goes in by-pass mode when I start the pump. The pump being Troy Bilt Model 020296-01. I replaced unloader valve even. Anything else I can do?


You replaced the unloaded valve. Are you positive you have the unloader screwed to pressure and not turned the opposite way? You will have no pressure if it is adjusted wrong. One other thing I have encountered is that the unloader has a ball bearing ... Pressure Washers

My pressure washer starts fine, shoots water OK. After running for 5-10 minutes cleaning siding I shut off machine. I go to start it again within a minute or two and the thing feels like it's just about seized. If i wait until the motor is completely cool, it will pull start freely and start right up. I think something is wrong with the pump, not the engine.

Have used this machine 6 years and just recently experienced noise that I eventually traced down to a bad recirculation pump bearing that failed due to a small leak in the shaft seal. Installed a new pump on Friday, 4/21/10 and that particular noise is now quieted. While the bearing noise was gone, there remains a pumped water noise that is quieted by manually adding about 1/2 gallon of water within the machine. So I now believe the water level is low, possib

Appliance had been working fine now all of a sudden no water is running in the dishwasher.The machine appears to run through all of its cycles but without water. The water pressure in the ajoining sink appears a little low though the water pressure in the rest of my home is fine. I see no water leakage anywhere.

... GE GSD1000 Dishwasher

My Troy Bilt power washer (using Honda GCV160 engine) has no pressure coming from the pump. I checked the water flow, everything seems fine. I believe the pump needs oil added, however, I can't seem to firgure it out (how to add oil to the pump). I did notice that previously, I used to see drops of oil coming from under the pump. I I have a bad seal, can I add oil and test the pressure before I change the seal? Please advise.


I had a similar problem. Turns out I had left the hose disconnected and some sort of wasp built a paper type nest inside the washer tube that the hose connects to. I had to take the pump off and take apart and then cleaned it out with a screw driver. ... Honda Black Max 2600 PSI Pressure Washer
