I have a Karcher pressure washer that is over a year old now, and today as it was a bit warmer i washed the wife's and then my car, now the problem i have is when i got to my car the pressure started to fluctuate between normal and very weak!
If i stop using it for a few seconds then pull on the trigger i get full power for about 5 seconds. Then it returns to half power again.
Now all this i found quite odd as i had just used it on the wife's car with no problems.
So, has anyone else ever had a similar thing and what was the cause?
These things are supposed to be maintenance free too.
