How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

A defective spark plug or ignition coil may need to be replaced. Your power washer`s spark plug is essential to keep it running since it ignites the air/fuel mixture. If your spark plug is dirty, cracked, or defective, it could be the reason your power washer won`t start.
PLEASE NOTE: You should always press the RESET button on the GFCI before using the pressure washer.
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.
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.
The electronic pressure switch automatically switches the pump on and off again on the pressure side as required. If there is no water running through the pump on the suction side, e.g. if the water tank is empty, the dry-run protection protects the pump against damage and automatically switches it off.
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.
You should check the outlet to make sure it`s working. Then, check if a fuse is blown or a circuit breaker thrown. If those both work, see if the Delay Start button or Control Lock feature has been activated. Sometimes it`s as simple as opening and closing the door to reset the washer.
Unused fuel inside the carburetor starts to evaporate after a month, leaving a thick and sticky tar-like material in the carburetor. This substance blocks gas movement inside the carburetor, and your pressure washer keeps shutting off while working.
If you cannot shut off the water from the trigger wand and there are no known issues with the unloader valve, there is likely an issue with the wand itself. The trigger wand has a mechanism inside of it so that when the trigger is released, the flow of water is blocked.
