The end of the chunky sprayer has a grad scale-one end is MAX and you think the other is MIN buut it is MIX-set on min it mixes the det. with the water --wont mix on any other setting.

Hi Guys there isnt a problem with your machine you just need to pull the end of the spray lance out -the lumpy bit where the water exits the machine (it kinda clicks out)

Hi hope i can help!!
Try this empty the detergent tank then have your machine ready to work then half fill the tank with warm water and use the machine, this may take a few attempts so dont think its a 5 min fix! What happends is the detergent when left in the machine goes thick and gooy the warm water thins this and eventualy cleans it out but dont use boiling hot water this may damage the seals.before storing machine away do this method.
Hope this helps .Sean

Bosch aquatak power washer will not start

Check to make sure the outlet (power supply) is energized. This piece of equipment is supposed to be used on a ground-fault protected circuit, so make sure the ground-fault on the outlet didn't trip or the circuit breaker (fuse) at the electric panel did not trip (or blow)
Check to make sure you are going through the proper starting procedures as outlined in your user's manual on page 8.
Follow the troubleshooting tips on page 10 of the user's manual.
Beyond that, Bosch requires that you have your power washer repaired at an authorized / qualified repair center.
I did locate a web site that shows an exploded parts view of the pressure washer, if that helps.
In case you don't have a user's manual, you can view it at:
Best wishes on your project.
