Problem: The pressure washer cuts out.

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.

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.
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.
The number one cause of low or no pressure when using a pressure washer is a blocked or worn nozzle. Blocked nozzles will prevent water from escaping, while a worn nozzle will allow too much water to pass through, causing the pressure to drop.
PLEASE NOTE: You should always press the RESET button on the GFCI before using the pressure washer.
It usually happens when the pressure washer runs out of gas. A blocked fuel filter can also stop a pressure washer from running smoothly. The gas flow to the carburetor will be limited. Solution: Check the air vent on the fuel cap is not blocked.
Check For Minor Problems Including Kinks Or Blockages

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.

To check for problems, a person needs to pull the trigger on the pressure washer. Surging occurs when the pressure is fine and then weakens. It is caused when the flow rate for the pump cannot be supported by the water supply. Problems can mount from there so it is important that it is dealt with as soon as possible.
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.
Reset your washing machine

There really isn`t a way to reset the washing machine. What you can do instead is power cycle it: Unplug it (or turn off power at the circuit breaker), wait some time for the electrical charge to clear out of the washer (usually 1 to 5 minutes at most), and then power it up again.

Should the light flash on my Window Vac when charging? The light on your window vacuum will slowly flash continually until the battery is fully charged. It takes 90 minutes to fully charge from empty. Once the battery is fully charged, the light will become solid.
Here`s how it works, devices from the Home & Garden range can be repaired in our repair centres. Machines within their warranty period are repaired free of charge subject to our Home & Garden terms and conditions.
Unloader valve failure — Power lags also result from failed unloader valves. This problem can be diagnosed by manually enacting the valve function. Open the tank and drain out the air and water, then close and power back up. If the compressor bogs down once again, the valve needs to be replaced.
And when a PRV fails, it can lead to an explosion. Damaged equipment, disrupted work flow, and even injury may result. Why take that risk when you can easily tell whether or not your pressure relief valve needs replacing or repair.
A trapped pressure unloader valve opens when there is an increase in pressure, so when the trigger on the gun is released (open) the pressure increases and opens the unloader valve sending the water back to a holding tank or back to the inlet side of the pump.
Machine Type: Gas pressure washers can typically run for about 30 minutes before they need a break. Electric models can usually go for an hour or more. If you`re using a hot water pressure washer, you`ll need to give it breaks more frequently – about every 15 minutes.
It Can Harm The Unit

Without water to cool and lubricate it, the pump will work harder than it should, causing it to wear down quickly. This can happen even with just a few seconds of running the pressure washer without the water being turned on. However, the pump is not the only part that takes damage.

It`s a frequently discussed topic between our technicians and homeowners on days that threaten showers. So, can you power wash in the rain? In short, yes. While there are safety precautions you must take, power washing in a light to medium rain can speed up and enhance the power washing process.
Distilled white vinegar can be used to remove stubborn stains from floors, windows and bathrooms.
Symptoms of a Failing Check Valve

For example, failing check valves will start to vibrate and even lose some internal parts when problems begin to arise. Other symptoms of check valve failure include reverse flow and excessive component wear and damage. Check valves will also emit noises as they start to break down.

Each time the power cord is plugged in to an outlet, the Reset button on the GFCI module must be pressed down to connect to electricity. Check to see if the Reset button has been pressed. Next, confirm the small plastic window below the Reset button shows RED in the window.
Simply turn off your pressure washer and disconnect the hose. Keep your garden hose attached and allow water to run through it for 20-30 seconds. Turn off your garden hose and reassemble. Try using your pressure washer as normal and see if that fixes the pulsing.
