Over 216,000 Cars Failed MOTs Due to Faulty Washer Jets in 2025
New data from the Driver and Vehicle Standards Agency (DVSA) has revealed a startling trend in MOT failures across the UK. In 2025, a total of 216,388 cars failed their MOT tests specifically because of faulty washer jets, averaging approximately 592 failures every single day. This issue has emerged as a significant yet often overlooked problem for motorists, with many drivers remaining unaware that such a minor component can lead to a test failure.
Many Drivers Unaware of Washer Jet Impact on MOT Results
Research conducted by eBay indicates that a substantial 26 per cent of drivers did not know that faulty washer jets could result in an MOT failure. This lack of awareness highlights a gap in routine vehicle maintenance knowledge among road users. Abir Tewari, UK director of Commercial Operations, Parts and Accessories at eBay, commented on the findings, emphasising the importance of regular checks.
"Small and simple parts like washer jets can go under the radar and motorists should routinely check them as part of their regular vehicle maintenance, especially before longer journeys and the annual MOT test," Tewari stated. "This vital part caused a significant number of failed MOTs last year, all of which are preventable with a low-cost, simple fix." In fact, fixing a faulty washer jet can cost as little as £1, making it an affordable solution to avoid a costly test failure.
DVSA Rules on Windscreen Wipers and Washers
The DVSA provides specific guidelines regarding windscreen wipers and washers during MOT inspections. According to the rules, inspectors do not need to check these components on vehicles with an opening windscreen or other means that provide the driver with an adequate view. However, for most standard vehicles, the regulations are clear.
"You only need to reject a windscreen wiper if it’s clearly damaged or worn," the DVSA states. "Windscreen wipers must continue to operate automatically when switched on." Similarly, for washer jets, the agency notes that "washers must provide enough fluid for the wipers to clear the windscreen effectively." These rules underscore the critical role that properly functioning washer jets play in ensuring driver visibility and safety.
Additional Windscreen Tips to Avoid MOT Failures
Beyond washer jets, other windscreen-related issues can also lead to MOT failures. Group 1 Autos advises drivers to be vigilant about any cracks or chips in the windscreen. "Anything larger than 1cm in the driver’s field of vision, or 4cm anywhere else, is an automatic fail," the company warns. While serious damage may require a full windscreen replacement, catching minor issues early can prevent more extensive and expensive repairs.
The company also recommends removing any attachments from the inside of the windscreen before an MOT test. "You should also remove anything attached to the windscreen on the inside ahead of your MOT - stickers in the corners are fine, but a phone cradle in the middle definitely isn’t," they note. By addressing these common pitfalls, drivers can improve their chances of passing the MOT and ensuring their vehicle remains roadworthy and safe.
