Hi I have a Wilks-USA RX550i electrical pressure washer and it started making very loud noise. It works fine apart from the noise that has become super loud! I ignored it (thinking it was just me...) and it overheated and turned off after about 10mins of use with a burned smell. this morning, after it cooled down it started fine but again super loud! feels like struggling! no sounds if I don't press the trigger but once i do loud!!! checked all connections and hoses ... no leaks nothign strange and water pressure is unchanged!unit works fine but it became super loud only when trigger pressed and washing.!

A loud noise when the trigger is pressed on a Wilks USA RX550i electric pressure washer could be caused by the pump sucking air. This can happen if the hose connections are not tight or if there is an air leak in the system. It is recommended to check that all hoses and connections are properly tightened.

The pressure of water coming out reduces considerably after 10 minutes.Why?

The water pressure in the Wilks USA RX550i may reduce after 10 minutes due to several possible reasons:

1. Clogged Water Inlet Filter – The inlet filter may be blocked, restricting water flow. Cleaning the filter can help.
2. Pump Sucking Air – Loose hose connections can cause air to enter the pump, reducing pressure. Ensuring all connections are tight may resolve this.
3. Worn or Incorrect Nozzle – A worn or incorrect nozzle can affect pressure. Replacing it may be necessary.
4. Clogged or Worn Unloader/Valves – If the unloader or valves are dirty or worn, they may need professional servicing.
5. Overheating – The thermal safety switch may trip due to overheating, requiring the unit to cool down before resuming operation.

Checking and addressing these issues may help restore proper water pressure.
