I have a Karcher electric power washer

Customer Question

I have a Karcher electric power washer, not sure which model, and the sprayer stream surges on for a second then off for a second. It will not just constantly spray. Any ideas?
Thanks, Mike ***

Hi Mike my name is ***** ***** welcome to Just Answer. Does the pressure continue to surge or once it loses it it doesn't come back ?

Ok. We will need the model number to check the location of the unloader valve etc , was it stored in a area where temperatures reach freezing

At work and can't get the model number until tonight. Stored in a heated area for winter. What is the unloader valve
Expert:  Briggs-Fan replied 5 months ago.
Being electric it may not have a unloader valve but may have a valve to regulate pressure that could be bad . Once I can pull diagrams we will check more into it .
Customer: replied 5 months ago.
The model of the Karcher electric power washer I have is K 5.540 or K 5.740
