All power cables cause a voltage drop, due to losses through heat, resistance etc.
The voltage in your home should be somewhere between 218 and 242 volts, which varies based on the proximity of your home from a local substation and the time of day (think of when everyone comes home after work and puts the kettle on!).
Over this entire range, your AVA high-pressure washer should work well.
If you are in the lowest half of this range, we sometimes see that the distance of the machine from the fuse box in your circuit can cause trouble, and this risk increases further for every meter of cable that is added between the fuse box and your washer.
If you must use an extension cable, then they must be at least to the following specification:
An extension cord can be a maximum of 10 meters with a conductive cross-sectional area of 1.5 mm2, and must be rated for outdoor use.
With a conductive cross-sectional area of 2.5 mm2, you can use up to 20 m length, and the cable must again be rated for outdoor use.
If you have low voltage and connect to a socket far away from the fuse box, typically in a garage or in the garden, you will already be at the lower limit of the voltage that the machine can handle.
If you have problems with the fuse blowing, or the machine switching off after some time, it is often related to the mentioned voltage loss. Then try without an extension cord or closer to the fuse box to clarify whether this could be the cause.
The most common type of extension cord for outdoor use is naturally a reasonablly thin and long cord. These are sold in large quantities, and most people with a garden and some tools with often have one or more of these. These are well suited for products that consume little electricity or that are not started frequently. A high-pressure washer (especially those which use an induction motor such as out V6, Master and Evolution) uses a lot of power and restarts every time you press the gun grip, so such a wire gets hot and can cause extra high voltage loss.
If you encounter elecronic issues, try without the extension cord or change to a thicker cord. You can also try moving the washer or extension cable closer to the fuse box in the circuit.
P.S. - Remember that a cable can appear thick even if the current-carrying part is thin! Therefore, check what is written on the cable and check that it matches the information above.
We recommend extending the high-pressure hose rather than the power cable. In many cases, this can be cheaper and gives you a better experience. You should not experience any pressure loss if using a longer cable.
