The yellow plastic stopper keeps coming out and sticking in the other end with the spring. What can I do to stop this from happening? 2 Answers
- This is happening on my pressure washer too - I purchased it in August 2019 and have only used it 3-4 times. Now any tool I attach leaves they yellow plastic ‘O ring’ behind when I remove the tool

Have you checked for anything broken that might cause it to come out?
After fitting new washers to stop leaking from wands connections, my K2 pressure washer only worked for two short sessions, two hours in total, then stopped. All plugs, fuses etc were checked. Is it the pump? What can I do? 2 Answers
- I replaced the capacitor - my machine just stopped working - water flowed through fine at low pressure but the pump stopped. New capacitor solved the problem

- you may have a leaking O ring
- Hi Crippen sounds like you have a fracture in the control head as I did, this opens when the machine builds up presure and then releases it through the fracture, it is likely the fracture is under the metal head plate used to secure the unit head hence you cant see it, I know your post is long ago but this may help others as when I read the posts on the espares site it was no end of help to me. If the seals are ok on everything else I suggest replacing the control head housing.
When the vario power lance is attached to the handle and I pull the trigger water pours out of the handle. If I remove the lance there is no leak. I have changed the o ring on the lance where it connects to the handle and also the o ring where the hose connects to the handle but it still leaks. The pressure from the lance seems good and it does not appear to be blocked the motor sounds normal and is not pulsing -any ideas?

It is likely the O ring seal may be damaged so not making a watertight seal, check it and replace if required.
