Water leaking from a loose connection can cause the unit to cycle on and off. Verify if the pressure hose has an O-ring at the connection. If missing, this will also cause the unit to cycle on and off. While the unit is running look for any water leaks that may cause the unit to turn back on.
If your machine cuts out occasionally, it could be because you are using an electric extension cable. Extension cables must always be 13 amp constant rating and no longer than 10 metres. Please check your operating instructions for correct specifications.
One of the most common reasons a pressure washer won`t stay running is because the spark plug is dirty or damaged. To clean the spark plug, you will need to remove it from the engine and use a wire brush to remove any build-up on the electrode.
The reason for this is because a build up of water pressure. On the water inlet or coupling the water can cause a pressure build up, popping the garden hose off. The aqua stop is a valve in the end of the garden hose connection that restricts water flow.
Some of the most common faults that will make your washer stop mid cycle include thermostat failure, problems filling up with water for the rinse cycle, or even pump problems that prevent your washer from draining. One thing that you can check yourself is the lid switch.
These include an incoming power problem, a damaged power cord, a malfunctioning door lid switch or lock, a defective user control board or timer, a broken drive belt, or a faulty or obstructed drain pump.
PLEASE NOTE: You should always press the RESET button on the GFCI before using the pressure washer.
It is normal for the washing machine to display 1-minute pause for easy care and gentle cycles. After a wash cycle, there is an anti-crease cycle which lasts about 30 minutes. During this remaining cycle, the display will show 1 minute, for example, and the OFF indicator light will illuminate.
The simple answer is yes, pressure washers can overheat. This is not unique to pressure washing machines – anything with a motor or power source can overheat in the right (or perhaps, wrong) circumstances.

A dirty inlet or discharge valve is the most common cause of a pulsating pressure washer. Dirt or hard water can get caught up in these little divots. It is important that you clean out these pieces every so often to prevent these kinds of problems.
Check for leaks

There could be small leaks, holes, or tears in your garden hose or high-pressure hose that are causing your pressure washer to lose pressure when you pull the trigger. If you find leaks, plug the holes or replace the hose, which should solve your pressure issues.
