Screwfix Power Washer switching high/low when on

Suckit

I don't know how to accurately describe this, but this started happening to power washer I bought in Screwfix, Only used once since I bought it at the start of the summer.

I wouldn't normally use it like this (holding it on while there is obviously something wrong with it), but did for the videos. I never let go of the trigger or o anything else. This is what happens when I start it. Has anyone got an idea how to fix this?

Should the hose be coiled up when your using it. It may have a kink in the hose so run it all the way out. It may also have an air lock so unplug it turn the tap all the way on and hold the trigger to let water flow through.

Check the little nozzle. Sounds like it's blocked. You should have gotten a very fine wire nozzle cleaner with it. Can also try unscrew the top part of lance and blow down or force water down from the tip back (reverse the flow as it were)

Thanks, will try them both tomorrow. I didn't realise there were any replies to this as I hadn't received any notifications.
