Description

How does a pressure washer capacitor work?

The capacitor helps in providing the motor with the first surge of power it needs to start and run efficiently. The capacitor releases the energy it has been holding when the pressure washer is turned on, helping to provide the necessary electrical current to power 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. 

How do you replace a damaged capacitor?

Disconnect the power and locate the capacitor near the motor or control panel. Safely discharge any residual electrical charge from the capacitor. 

Remove the old capacitor by detaching wires and unfastening it from its mounting. Install the new capacitor, secure it in place, reconnect the wires, and test the pressure washer to ensure proper functionality. 

This capacitor by Karcher is a genuine pressure washer replacement part.

Great product, did the trick!!

Jetwasher stopped working during a major job and after looking at YouTube videos all parts pointed to the capacitor. Ordered a replacement capacitor easily from Ransom Parts and delivered swiftly. Got back to the YouTube Tutorial and fixed it easy enough. All working a treat thanks to Ransom Spares. Would highly recommend.

Fit for purpose

Needed a genuine spare for my Karcher pressure washer had established the fault as being the capacitor despite my model being five years old was able to identify and source the part quickly with Ransoms data base, and as it identified as being in stock was sure it would arrive quickly." It did not" but after a call I was told it is on its way to them. I asked if it could be upgraded for a quicker delivery to me. The customer service rep was most pleasant and efficient and expedited my request and I received it the next day. I fitted it and was using my Karcher within the hour. Thank You for the Great FIT FOR PURPOSE SERVICE. Tom D

This product fitted and worked great with my Karcher K4 Premium ecologic pressure washer model 1.180-661.0. The packaging of the part was great. I would recommend RansomSpares products to anyone.

Great product.

It's a capacitor. What more can be said. I got it to fix a karcher pressure washer, but alas, it wasn't the capacitor that was broken. After tearing the karcher apart I found a seal had torn on the compressor and it had leaked all lubrication, before rusting and ultimately destroying itself. Pretty rubbish build quality really. If you're buying this capacitor for the same reason, make sure it's the capacitor you need first. If it is, get this one, it's great! If not, get rid of your karcher and never look back!
