Shop windscreen washer pumps at Truckstop Group
A windscreen washer pump is a simple component with an outsized consequence when it fails: without functioning screen wash, a vehicle will fail its MOT, since clean glass and effective washers and wipers are a checked item. Pumps typically fail through worn brushes, a seized impeller, or a perished seal that lets fluid leak past rather than reaching the jets.
Specification varies more than the simple job description suggests. Some pumps run a single outlet feeding the windscreen only, while others feed a combined system covering the windscreen and headlamp washers. Voltage and outlet configuration both need to match the existing unit, or the replacement won't perform correctly even if it physically fits the reservoir.
Before condemning the pump itself, check the reservoir for debris or a blocked strainer, since a clogged inlet can mimic pump failure by starving it of fluid. A pump running dry or against a blockage will also wear out faster than one drawing clean fluid.
Frequently Asked Questions
Why does a windscreen washer pump fail an MOT?
Effective screen washing is a checked item during an MOT. A failed pump means the washers can't clear the screen properly, which is enough to fail the test even if the wipers themselves work correctly.
What causes a washer pump to fail?
Common causes include worn internal brushes, a seized impeller, or a perished seal that allows fluid to leak internally rather than reaching the jets. Running the pump dry repeatedly also shortens its lifespan.
Do all washer pumps have the same number of outlets?
No. Some feed the windscreen only, while others feed a combined system covering windscreen and headlamp washers. Check the outlet configuration on the existing pump before ordering a replacement.
