Question about Karcher K2.26 Electric Power Washer

1 Answer

Karcher K 3.97M electric presuure washer cycles on/off.

The pressure washer will cycle on & off when the trigger on the spray wand is not depressed. It runs and sounds normal when the wand is in use. The spray pressure has decreased over the 3 years (2006) that I have owned the machine. It was only in the 3rd year that this cycling problem started.

Hi;
It has an internal water leak or a seal or valve is leaking air. These machines are warrantied for 2 years and that is about all you can expect from them. Having it repaired professionally would cost about 75% the price of a new machine. If you are handy enough to get into it yourself, e-mail me and I will send you a diagram. (firehead@rogers.com) Part prices are expensive in Canada but not bad in the US. I don't know about other countries.

If a washer not used for a few years would that cause any problems


Hi and welcome to FixYa, I am Kelly
The seals do have a tendancy to harden / dry out or... corrosion prevents the unloader bypass valve from moving / operating properly. I recommend you put a little oil (2 oz maybe...) through the unit on purpose via the inlet water connection. Then connect your water hose and force the oil though the unit with the air in the water supply hose while it purges. DO NOT turn the unit on until your sure the water supply hose has purged out all air. Then turn on the unit making sure that you cycle the wand trigger rapidly for a few minutes by cycling the trigger until the high pressure hose is not so rigid then let the high presure hose charge fully again. Cycle trigger wait, cycle trigger wait. 1 second bursts until you get full pressure. Then use normally. This usually wakes up pressure washers that have been resting :)

Thanks for choosing FixYa,
Kelly

Turn water on then actuate wand trigger. Pressure washer leaks when wand trigger is actuated and has very low pressure/flow output. After releasing trigger the pressure cycles on - off at approx 1 second...


You gave a very close solution yourself for the problem. But other leakages can cause such symtoms.Forexample a leaking head or a leaking chemical inlet. These can be caused because the spill valve (pressure control valve) is stuck. When this valve stucks it will leave a micro switch ON. So the machine keeps working with the gun closed. This will in turn creat internal pressure and damages the head, valves and chemical non-return and even damage outlet hose. So besides fixing the leakages you must check and service the spill valve. I often replace the spill valve. One must also checks if the micro switch is faulty. Now very important that what you mentioned that the machine cycles at one minute intervals, with trigger closed...this is most probably always the spill valve fault. If you open machine you see a place where there is a wire..this belongs to the micro switch...under you find the spill valve. Intake and suction valves may now also have a fault. Also there are systems with non-return valves at the machine outlet. You have to tackle by elimination. Fix the leakage..then tackle spill valve and micro switch.

It sems you have a blockage in the tip. If you get a grain of sand in the nozzle it will act like this. Get a piece of fine wire and poke down the nozzle to free it up.

Karcher pressure washer trigger problem


The wands that it will not run with would most likley have a little dirt in the tip of the nozzle. This would not allow the water to flow through in turn activating the pressure switch and shutting the machine down

The machine has a pressure leak. Check for a cracked controll head or either a leaking outlet elbow. The machine will short cycle if the holding pressure can not be maintained
