The reason why a machine makes noises when you pull the trigger is usually to do with air in the system. This can be easily solved by flushing the machine through with just a pistol grip (without a nozzle) for a little while, until you see a steady fine stream of water coming through. Then put on nozzle and try again.
Other causes could be debris blocking a valve from closing, or a valve that doesn't move as freely as it should.
Such problems can often be solved very easily. The solution below covers the following symptoms:
When a machine starts and stops without the trigger ebing pulled - i.e. in standby. Applies both when it is occasional AND when it starts and stops continuously
When there is poor pressure, or occasionally poor pressure
When there are strange noises while flushing, or when you are not flushing
Squeking sound as a result of cavitation - i.e. squek when the pump stops
Place the machine on its back and remove the water hose. Spray CRC, WD40 or similar into the water intake, so that the pump is well filled with lubricant. Feel free to start up the machine with the main switch for a few seconds to draw the lubricant into the pump - and then turn it off again off again, so you can repeat the above process one more time.
Let the lubricant do it's work.
Then connect the hose, set up the machine and flush through with the gun in bursts 10-15 times without a nozzle.
This trick has been used since the "dawn of time" (or since pressure washers became popular!), and therefore also works well with AVA. In this way, dirt that sits in unfortunate places can be washed out, and the problem is thereby often solved.

We are currently working on translating and rewriting all of our articles into English from the original Norwegian. Whilst we are proud of the quality of our language skills here at AVA, we are aware that there may be some slightly odd syntax and wording present in the articles that have been translated. The approach we have taken to this translation process is in order to get as much information as possible out to our customers in a timely fashion. Thusly the ongoing revision and updating of these articles by our British-Norwegian team will include slight changes to how the text is put together in order to bring it more into line with correct British English.
