Question about Karcher 1750 Psi Elec Pressure Washer

Open Question

Pressure washer will not kick-in; When the

Pressure washer will not kick-in; When the machine is set up initially it will work correctly until the trigger is released. Press the trigger again the compressor will not kick-in so only weak dribble will dispence. If I remove the nozzle attachment the compressor will kick-in. I then need to 'empty' the water from the nozzle and re-attach for jet wash to work correctly again.... until I release the trigger... very annoying. The gun / lance has been changed - no effect, as has no nozzle attachments. The nozzle, lance and pressure hose have been cleaned and blasted with compressed air to remove any blockages. There is no apparent leakage and there are no mains water pressure issues. Machine is roughly 18 months old, but reciept / warranty has been lost. Any thoughts?

SOURCE: north star petrol pressure washer.

Sounds like the regulator is sticking or is airbound. loosen the water connection and then tighten it back. Could also be that the trigger gun is faulty or needs adjustment. Hope this helped

SOURCE: honda pressure washer cuts out when lance trigger released.

You most likely need to set your valve clearances. If it is hard to pull over or the recoil snaps back after starting your valves need to be set for sure. This may not be the entire problem but it is a good start. Also change the spark plug, a bad plug will cause odd problems and is too cheap not to eliminate as a source. In addition check your fuel, pour a little out into a white container (I like spray paint can caps for this) and look at the color. If it is yellow to orange it is bad. You can pour it into you car, the car electronic sensors will compinsate for it quality but a small engine can't. Use a NGK BP6ES or BPR6ES plug.
You need:
Feeler gages
10mm open end wrench
14mm open end wrench
1 long shaft screw driver or rod
1 spark plug socket and ratchet

Remove the spark plug and the valve cover. Pull the recoil over slowly until the intake valve opens (intake is closes to the carb and it will go down when it opens). Now put your long screwdrive down the spark plug hole. Slow pull the engine over until the screwdriver handle is at it highest point, this is top dead center. It may take a few attempts. Now check your valve clearance between the rockers and the top of the valve. The intake should be .006 and the exhaust .008, both can be +/- .001. To adjust: hold the large nut with the 14mm then loosen the small one with the 10mm. Lefty loosey. Now turn your large nut until you get the correct setting and then tighten the small one the lock it in. It may take a few attempts and alway reverify your setting after you lock it down. Once done, find top dead center again and reverify. Now your valves are set.

SOURCE: Pressure washer lacks pressure initially?

Dear allbusiness9,
This problem is most probably due to a faulty Spill Valve( also called Control Valve). When the gun is released the spill valve is compressed and it either closes a micro switch or just opens from the bottom and keeps the water circulating. All spill valves keep the water circulating from the bottom part. Now when the gun is pulled (opened)...the spill valve extends and closes the bottom part, and thus water goes out of the nozzel. When you work with no nozzel, there is enough water flow to close the bottom part of the spill valve. So when the nozzel is placed back there is no chance that the bottom part leaks water. When the gun is started with the nozzel....the bottom part of a FAULTY spill valve,..will colapse and pressure drops. So to fix the fault you must change the Spill Valve. In some occasions, I also found that suction valves give this problem. A faulty sucktion valve will colapse under high pressure, and lets water pass the other way round.
But in my opinion and experience, your problem is in the Spill Valve.
Regards,
Fulltech.

SOURCE: Ex-Cell VR2500 Builds Pressure but Won't Spray

I have a similar problem and diagnosed it to be a problem with the gun. I spoke to a technician that services this pressure washer and he walked me through all the diagnostic steps. The pump is working because there is pressure being built up and the gun sort of works because you can get water out before the washer is started. The technician said that the mechanism inside the gun is either clogged or broken. I am going to Home Depot or Lowes to purchase a new gun and will try it tonight. Guns are only about $30-40. He said generic is fine as long as the thread matches and PSI is in range. Good luck!

Miele Touchtronic W1213 Front Load Washer: The washer keeps adding and then draining water continuously. One time, the cycle ended and the machine continued to add water and drain endlessly....until I...


hi - If I remember correctly this particular series had a time related sequence built into the programme, whats happening is the timer has picked up the false readings when the pressure activates the switch.

Suggestions to look into - leave power off & turn water back on - does water run into the machine (faulty valve); turn power on initiate a cycle water runs, then turn power off - is water still running? (faulty valve)

From experiences on the field, theres a slim chance that the pressure tube has a hole in it from the vibrations over time. This effect will not create enough pressure in the tube to activate the pressure switch, the only other problem would be the pressure switch itself.

Tyre pressure warning light showing when pressures are correct


Hi, the tire pressure monitor detects any changes in the tire inflation pressure. Therefore, it must initialize and store it in its memory if the tires or wheels have been replaced, re-inflated or the tires have been rotated. You can re-initialize the system by following these steps:

1. Check and make sure that your tires are inflated to the correct pressure

2. Turn the ignition switch to the ON position. If the low tire pressure warning light comes on, push and hold the tire pressure warning reset switch (in the glove box) until the warning light turns off and then release the switch.

3. Now press and hold the tire pressure warning reset switch until the low tire pressure warning light blinks three times.

4. Initialization is *not* completed until driving at the vehicle speed of 19 mph or over for more than one hour. the tire pressure monitoring starts when initialization is completed.

After loading washer water starts running then f1 code starts flashing. change to different setting and then it will go


The F1 error code on this washer indicates a Primary Control Board failure.



It is likely that the machine control board will need to be replaced to correct this problem.



The part number for the machine control board is undetermineable because you have not provided me with the exact model # of your washer.



The procedure for replacing the machine control board is provided HERE

NOTE: Be sure to unplug the washer to disconnect electrical power before accessing internal components.



There is a slight possibility that a problem with the pressure switch hose could be causing this problem.

A pinched or twisted air hose can cause this fault code.

When you open the console, check the air hose connected to the pressure switch on the machine control board.

If it is pinched or crimped, I recommend rerouting the hose to resolve this problem.

This may fix your problem without replacing the control board.



NOTE: You may want to check for this condition before ordering the control board. Most electronic control boards cannot be returned for a refund or credit.



If you find no apparent problems with the air hose on the pressure switch, then replacing the machine control board on this washer should correct your problem. There is a risk involved in replacing this part yourself.

As noted above, you could have a problem with the air pressure hose that is not apparent upon your initial inspection. A service technician would normally need to properly and thoroughly diagnose this problem before replacing the control board.

Lack of pressure after releasing the trigger on the wand


Hello awcockerill:
This sounds like the bypass (unloader) valve is sticking. Here is a diagram of your machine's pump. On page 2.4 see part #1. The top of this assembly is a black plastic cover. Remove all of assembly # 1 carefully. Under that is part #8. This is the bypass valve. You need to pull this out, check that the o-rings are not bent, worn or damaged, then lube it good with a VERY VERY good waterproof grease. Re-assemble it and all should be well. The part numbers are on the diagram but where to get them depends on were you live. Karcher web site may give you a number to call. Good luck.
