Washer Pumps: Repair, Replace and Maintain

Washer pumps supply fluid to the windscreen and are small but essential components. When spray fails or flow is weak, the pump is often the culprit. This guide helps you identify problems and offers practical advice on sourcing replacements and maintaining the system.

Signs of a failing washer pump

If there is no spray when the washer control is operated, or if the pump runs but fluid does not reach the nozzles, investigate tank level, filters and hoses first. Electrical checks include fuses, connectors and switching. Failure due to freezing, clogging or worn seals is common and straightforward to fix.

Selection and installation pointers

• Match pump voltage and mounting style to your vehicle.
• Inspect hoses and nozzles for blockages before replacing the pump.
• Replace or clean the inline filter if fitted to the reservoir.
• Consider genuine-fit or aftermarket pumps with clear compatibility listings.
• Check for clearance items and compatible refurbished units to save on cost.

Replacing a washer pump is usually a quick repair. Follow manufacturer guidance for winter operation and use suitable washer fluid to minimise freezing and deposits that can damage the pump.
