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 :

If the pressure washer trips the fuse board or blows the electrics in your home, make sure there`s no water in the switch or the other electrical items – and again examine the capacitor if your model carries one.
5 Amp Fuse for Aqua Blast® Pressure Washer Ignition.
When an RCD circuit breaker trips or a fuse blows when you switch the appliance on or off, this is usually caused by leakage to the ground or a short circuit. The problem can be caused by the incorrect connection of the appliance.
Overloaded circuits, short circuits and ground faults are all legitimate reasons why your fuses blow on a regular basis or causes for your fuse box to trip out. Other causes could be a result or ageing or faulty wiring as well as power surges.
Standardised Fuse Ratings

The British Standard for plugs, BS1363, has standardised on just two preferred fuse ratings, 3A and 13A, however, any fuse rating up to 13A can still be used. 3A fuses are marked in red and 13A fuses are brown.

If you replace it with a 5A fuse you will lose part of the protection the 3A fuse was intended to provide. In case of a failure of the device the fuse is suppose to protect, the result of using a larger fuse could be to damage the device to the extent that it could not be repaired. It could also start a fire.
Overloaded Circuit

The most common cause of a blown fuse we see as experienced Electricians in Sheffield is when something draws too much power from the circuit. This is most often caused by either too many lights or from using too many plug-in appliances at once.

PLEASE NOTE: You should always press the RESET button on the GFCI before using the pressure washer.
Check the Fuse: If you have done all the repairs and replacements and your electric pressure washer is still not working, it may have something to do with the fuse. Inspect the fuse if it is blown or not. Replace the blown fuse with a new one and test the device again.

Why dose my Karcher K2.35 keep blowing the gun hose off?
ANSWER : There is a good chance you are missing the black plastic clip that holds the hose into the trigger gun. If you look at where the hose goes into the gun there should be a flat slot where a black plastic clip would slide in and keep the hose into the trigger gun.

Turned pto off when finished mowing then turned it back on and it does not come on
ANSWER : Check the wiring to the PTO first. if it is good either the PTO or its inline fuse has failed. try the fuse first as it is much cheaper. if it just blows again you are back to replacing the PTO.
