Your pressure washer’s power starts at the capacitor.
The capacitor helps in giving the motor the initial burst of power it requires to start and function well. When the pressure washer is turned on, the capacitor releases the stored energy to supply the required electrical current for the engine.
What damages the capacitor?
The capacitor becomes worn out with continuous use and results in reduced capacitance or even failure. Voltage spikes, power surges, or electrical faults can also damage the capacitor.
Exposure to excessive heat, moisture, or contaminants can lead to deterioration or corrosion of the internal components, affecting the capacitor's performance.
Is it a genuine spare part?
This capacitor by Karcher is a genuine pressure washer replacement part.

Fits perfectly
Thanks for the accurate dimensions. Replacement capacitor looks different, but it fits my K4.200 perfectly and now the washer works again.

Good quality and fit, and fast delivery
My karcher high pressure washer did not work when I plugged in the power cord. So I chose capacitor breakdown as the first place and did not sell it in my country, so I bought it here. The time it took to receive it took seven days, and it is fast for products shipped from the UK. (In my experience, it usually takes more than seven days if sent from the UK.) If you purchase the product outside of the UK, I strongly recommend it. This product worked well with my K5.700 KR version, but it was not the main cause of my high pressure washer.

Great product, poor delivery.
Does exactly what it should, easy to fit after machine dis-assembly. Great value. However part did not arrive for two weeks due to not being in stock when web page indicated in stock andr equired odering. In addition when subsequently in stock was not dispatched for a further 4 Days. A straight forward purchase let down by misinformation (both on line and telephone) and delay in delivery That said I would use Ramsomes again.
