SOURCE: karcher washer went dead

Dear jimbocom,
The problem is that the spill valve got stuck. When the machine is working and the gun is closed, a valve( spill valve) moves with the accumilated pressure and switches the machine off. So what happened is that when the spill valve did its job, it found no water...and remained stuck. This leaving the machine in an off position. Service and lubrication to the spill valve must be done or completely replacing with a new spill valve. In my opinion you have no serious damage, but this job must be carried out by an expirienced technician.
Regards,
MG.

SOURCE: Electric Karcher pressure washer surging when turned on

Dear firenutt681,
One simple thing you can do, is to check for leaks. Check if hose at machine is leaking. Check gun if it is leaking. You can also check if water still comes out of lance nozzel. These leaks however so small, will cause the machine to surge.
Another reason is due to a faulty SPILL VALVE. This spill valve( often called CONTROL VALVE) will contract when the gun is closed. When it contracts under the enclosed pressure it will switch off the machine by means of a Micro Switch. Now if this Spill valve is faulty it will loose its compression under pressure and puts on the micro switch again. This can be seen once in a while or more frequent, as in your case. I sometimes do service Spill Valves, but mostly I replace them with a new one. I do not know the model number of your machine, but normally you have to open the cover and you should spot the spill valve on the head. Most probably you see a thick wire or a cap containing the micro swith. If you find the micro switch, you have found the spill valve. Sometimes it is a bit hard to pull out the spill valve. Myself, in various Karcher models I remove the spill valve by trying to feed water and put on a bit the machine. In this way the spill valve will be spitted out.
Another reason which makes your machine surge, is leakage from from the detergent inlet.
If you do not see no leakages at all....then for sure it is the SPILL VALVE.
If you cannot do this job yourself or you do not find spare parts...you can continue using the machine as it is...but before closing the gun...switch off the electricity. I only recommend this in an emergency. You do this so that you do not leave the machine surging. This surge will for sure damage the electric motor and the capacitor (assuming it is single phase).
Regards,
Fulltech.

Is liquid leaking from the base, when the Pressure washer is on ?
I have the same Problem, the leak is from the seam of the Manifold housing. There is a small crack in the seam. A manufacturing defect.. A New Manifold Complete Replacement is $61.03, about the half the price what I paid for this pressure washer at Walmart... :( If under 1 year old, and you can find a receipt,Karcher will replace the whole Pressure washer under warranty.

Hi, My karcher 5.86 has suddenly stopped working. No power/ noise from washer when power is switched on. Fuse & source is obviously fine. Im going to obtain relevant torx screwdriver this week to open...


If its not the fuse in the plug it might be the on/off switch. I would check switch for continuity with a multimeter to rule it out first.

How do i fix my dryer ... it wont start all of a sudden?


A closed switch should show virtually no resistance at all, and 30 ohms is therefore pretty high. Think of a switch as merely putting two pieces of a broken wire together, or pulling them apart again-- there shouldn't be any resistance at all!

Karcher just stopped working


It sounds like a motor capacitor burned up. Alternatively, a wire could have vibrated loose from the capacitor. Look, but do not touch the capacitor(s), as they can hold a charge that can hurt -- or even kill you.

The trick is to be certain they are discharged before handling. To do this, use a screw drive with a well insulated handle and touch the top of the capacitor where the wires are. The metal blade of the screw driver should touch both sides of the capacitor at the same time. Then, if there is any charge being stored, you will see a pop and that's it -- it is not discharged.

You can buy a new capacitor at any place that sells AC and Refrigeration supplies. Take the old one with you so they can match the microfarad capacity. Just venturing a guess here, but if you want one that fits perfectly back into place you may have to order it from Karcher (because those units are built in Europe I think).

2. The motor may have shorted (gone bad). If that has happened, perhaps you have some warranty. Electric motors are generally warranted a little longer than the PW in general. With Karcher, I don't know. If there is no warranty on the motor, it may be better to buy a new pw than to replace the motor.

3. The problem could be a mechanical issue with the pump/unlooader. However, I would think this would be the least likely scenario.

If what I've given so far doesn't get you rolling in the direction of being resolved, please followup here. I'll be watching. And if it does get you moving in the right direction, please take a sec to rate me. Thanks!

When i switch my karcher on the motor makes o noise and does not turn


This sounds like you may need a new capacitor. It is not a costly part to get. What the capacitor does is "jump starts" the motor so if it broken the motor will not start.

A test you can do is if you take off the front caseand then set the machine up as if you were going to use it. then when you turn on the machine quickly push the fan blade of the motor with a flat headed screw driver. If this makes the machine start to work, then you know that you need a new capacitor.

Just be carefull when doing the test.

Please remember to thumbs up :)

My karcher hds 745 has started blowing fuses. it switches on the power light comes on and it makes a buzzing noise for about five seconds and then blows the mains 13amp fuse. i have replaced it twice but...


Dear dumbelldaveb,
Having a 13A fuse I am concluding that the machine is single phase. Most probably you have a faulty capacitor. Check the capacitor and if you find it expanded and leaking...then you must change it with a new one. If you see the capacitor is normal just the same it could be shorted. So change the capacitor with a new one and try to start the machine WITHOUT LOAD. Which means no water inlet and no gun attached. Doing this you can also remove temporarly the micro switches. If the motor still hums, then most probably there is a fault in the electric motor.
Now if you find out that the fault is the capacitor (which in my opinion it is the case)...you must see why the capacitor broke. If when using the machine and the gun is closed, the machine starts on and off on its own,...this will damage the capacitor. This on and off fault could come from a leaking gun. Or a leak from the seals. Whatever....the machine must not be left going ON and Off when the gun is closed. This ON and OFF could be due to faulty micro switches and control valves.
I am very sorry to mention a lot of things, but I hope as in many cases,..the changing of the capacitor will solve the problem. I wish to add that the electrical lead wire must be checked. On many occasions I found that the electrical lead wire from the plug to the machine was damaged and shorted, ..due to pulling, wear and tear.
Regards,
Fulltech.

My saw wont run only buzz


Sounds like teh capacitor has blown. These machines use normally use induction motors so they need the capacitor to take a charge and give the motor a kick in the right direction. You could CAREFULLY turn the machine on and spin the blade by hand. If it runs now then you will need a new capacitor.
