Question about Bosch AQUATAK 115 PLUS Pressure Washer

Roto power lance 'jet' keeps sticking

The jet of water keeps sticking and comes out in a sharp straight wand rather than a 'rotational' jet of water which does the job. I've checked for blocks etc... Is there anything I can do please ?

Hello, myK236 root jet nozzle has stopped working. There is no rotation of jet. Also it just stared pulsing on one wand, but works fine with the root jet wand. Thanks


the rotating nozzle is clear and that is why it is working It requires pressure out of the jet to make it rotate so a simple tap on the ground will generally get it rotating again as for the straight jet and pulsations
the jet is blocking up
unscrew it out of the wand and clean it out
the pulsations are from the pressure regulator unloading from a blockage ( same as taking you finger off the trigger ) coming and going in the jet
as the jets blocks up the increase in pressure operates the regulator and as the blockage moves around the pressure regulator again works giving full pressure until the blockage again occurs

The water is not coming out from water hose


Check that the nozzle jet is not clogged. To do this removed (unscrew) the nozzle at the end of your wand. Squeeze the handle. If water sprays out then your jet nozzle is clogged/corroded and either needs to be cleaned or replaced. This happens sometimes if you leave the wand sitting for several months with water still in the line.

Karcher 620m wont work at high pressure


what you describe indicates a problem hose or block nozzle jet
if it doesn't play up with a normal nozzle then it is not the hose or jet but that particular wand and nozzle you are using
do you have a sufficient inlet water supply for the pump

I discovered tiny ball bearings in my hot tub. Where could they come from? The hot tub is working fine.


The ball bearings from your spa are from a roto head jet. Typically they are from one of the larger sized jets and they make the swivel action in the roto swirl jets function smoothly. You can determine which jet is coming apart by the loose function of the center nozzle. The jet can be removed and replaced to solve this problem. Most jets screw out but when they have deteriorated a lot, you may need plyers to take the jet out in pieces.

Preasure washer want preasure up. engine runs find but wand want kick into high preasure


Hello,
Start the engine on your pressure cleaner then with your lance change it to low pressure as if you were applying detergent i think your model has the 5 different quickfit jets put the large derergent one in and give it a hit...
Then put the high pressure jet back in and see if it will build up pressure now, if this works then your bypass/unloader valve is sticking in the head it will need removing and cleaning up and lubricating...

This is the most common cause of not building up pressure and is usually caused by sitting around and not using the pressure cleaner regulary...

Good Luck!!! Hope this helps

Kind Regards
Brad

When garden hose is connected to the pressure washer no water comes out of the wand, engine is off.


Dear radcongirl,
Try removing the high pressure hose from the machine. Then connect the water hose and see if water comes out of the outlet.( you can also try this by putting on the machine for a few seconds). If water comes out of the outlet, then you have a problem in the high pressure hose or the wand and trigger. Check also the lance and nozzel for blockage.
I do not know what kind or model of machine you have, but most machines the water always comes out of the outlet when water is fed to the inlet. In bigger machines this cannot happen because they have a reserve tank.
Regards,
Fulltech.

No pressure unless i take the nosle off , pull trigger and put nossel back on then it's ok until i release the trigger again ?


unloader valve sticking in the pump head. remove unloader valve/ pressure reducing valve as per parts manual.

It will probably be caked up in white crystal type deposits if its an aluminium pump head. clean off the deposits and inspect the 'o' rings. if 'o' rings ok , apply silicon grease and refit.

It could also be a partially blocked lance jet not allowing enough water to come out of the lance if it is a flow sensitive unloader valve.

No pressure on certain settings


Dear Osville,
It is not clear what type of lance or nozzel you have. You said that the machine works fine with the circulating water jet(the turbo). So it seems the machine is fine. I do sometimes service variable nozzels and variable lances. But the best solution is to replace nozzels and variable nozzles and lances with new ones. Regarding the fan spray setting it could have no pressure because it might be in the chemical setting. The chemical setting lets out a fan shape flow of water, but with less pressure. The chemical system only works on low pressure in domestic washers, that is why it needs a low pressure flat spray. The pencil jet has 2 jets comming out because if it is a lance or nozzel with ball bearings, these ball bearings must have stuck in a wrong position. Also 2 jets can come out, due to a damaged nozzel hole.
Altogether, the best advice is to buy a new nozzel or lance...which ever your machine uses. All Karcher machines have their own specific nozzels, lances and high pressure hoses. You cannot change these from one model to another.
Regards,
Fulltech.
