OK here is the solution. There are six plastic vaules inside the pump if you have any mechanical skills you can fix this.
These plastic valves melt when you leave your pressure washer running for a short period when you are not pressure washing. once this happens the pump becomes cloged and does not function. I spent alot of time and research on finding the parts for replacement. I called the main company of this washer pump and here is the toll free number
800-999-2245 and the web sight www.pressureparts.com but to save time just call and talk to the service tech tell him you model number and he will give you the part number.

Sounds like you may need to remove the valves to check for any dirt etc. Is the machine juddering when on pressure. If so then it will be the valves that just want removing and cleaning

You should use what the pump manufacturer recommends. Typically a 30wt non-detergent (non foaming) oil. Do not over fill. If there is a sight glass half way is normal. Or if it has a dip stick follow the mark there.
