Losing pressure is the most likely fault your corded pressure washer will suffer, accounting for 19% of faults overall, according to our latest survey.
Water leaking from inside the washer (16%) and the motor failing (12%) are next most common.
For petrol pressure washers, the most common faults are the choke failing and the motor failing (both 17%).
Knowing which brands develop the most faults, and how quickly, is vital when buying a pressure washer. That’s why each year, we ask Which? members to tell us whether they're happy or have experienced problems with their pressure washer, in our unique gardening product experience survey.
Our January 2022 survey data takes into account the reported fault rates and the speed with which they occurred. In our latest analysis, we've looked at the performance of some of the biggest manufacturers – including Nilfisk and Karcher – and have calculated a customer score for each, so you know which brands to choose and which to avoid.

Loss of pressure is the biggest issue for pressure washers. There could be various reasons causing this but before taking it to a repair shop or replacing it, consider the following:
On average, five and a half years passed before those who bought their corded pressure washer between 2015-2021 experienced the first fault out of a sample size of 3,203 people. Of those that reported a faulty product, 39% carried on using it as normal and 19% had it repaired by someone they know.
Nearly five years passed before owners of petrol pressure washers experienced their first fault out of a sample size of 80 people. 57% carried on using it as normal and 50% said their pressure washer was replaced by the manufacturer or retailer where they bought it.

Which? has a wealth of information on the UK’s favourite garden product brands. Every two years, we ask Which? members to tell us about the garden products they own – from how satisfied they are with their product, to the faults they experience with them once they get them home. This year, 8,881 members told us about their products. We calculate a brand's customer score based on the results of our biennial survey.
Our Product Experience surveys, combined with our extensive lab tests, mean we can recommend the best pressure washer you should buy.
This data is crucial for our testing, too. If a brand falls far below the category average, we take away the manufacturer's Best Buy recommendations and won’t recommend any of its products unless a marked improvement in satisfaction is shown.
