BMW M5 Windshield Washer Pump: A Guide for the F10 & F90 Generations
Is your M5's washer system failing to spray? Here’s what you need to know before you replace the pump.
- The most common failure is not the pump motor, but a clogged filter screen caused by using improper washer fluid.
- Diagnosis is simple: if you hear a hum but get no spray, the filter is clogged; if you hear silence, the pump has likely failed.
- Replacement is a straightforward DIY job that takes about an hour, involving removal of the passenger-side front wheel and fender liner.
- High-quality aftermarket pumps offer significant savings over OEM parts with no loss in performance for this component.
Is Your M5's Windshield Washer Failing?
For owners of the F10 (2012-2016) and F90 (2018-2020) BMW M5, a non-working windshield washer is a common, yet usually simple, issue to resolve. Before you suspect a major failure, it's important to understand the typical causes. Often, the pump motor itself is not the problem. The most frequent issue is a clogged filter at the base of the pump. This guide will walk you through diagnosing the problem and choosing the right replacement part.
Diagnosing the Problem: Pump vs. Clog
A simple test can often tell you everything you need to know. In a quiet place, activate your windshield washers and listen carefully near the front passenger-side wheel well, where the reservoir is located.
- You hear a humming sound: If the pump motor runs but no fluid sprays, the issue is almost certainly a clogged filter screen (strainer). This screen can get blocked by algae-like substances or gelled washer fluid, especially if non-approved fluids or tap water have been used.
- You hear nothing: If there is complete silence when you activate the washers, the pump's electric motor has likely failed. It could also be a blown fuse or wiring issue, but a dead pump is a very common culprit.
A Note on Fluids
BMW has issued a Technical Service Bulletin (TSB SI B61 01 09) regarding the filter screen becoming clogged with an "algae-like" substance. This is often caused by using plain tap water or certain aftermarket washer fluids, like some Rain-X formulas, which can create a gel that blocks the filter. To prevent this, always use a quality, pre-mixed washer fluid or BMW-branded concentrate.
Choosing a New Aftermarket Pump
If you've determined the pump motor has failed, replacement is the next step. While you can purchase an Original Equipment (OEM) pump from a BMW dealer, high-quality aftermarket options provide identical performance at a significant cost saving. Brands like Trico are established manufacturers of automotive parts and offer direct-fit replacement pumps that are engineered for easy installation without any modifications. 🎬 See how a Trico replacement pump is designed and installed. An aftermarket pump is a practical and budget-friendly choice for this repair.
Pro Tip: Replace the Grommet
The washer pump is press-fit into the reservoir using a rubber grommet, which also acts as the filter screen. These grommets can degrade over time, causing leaks. Since you must access the pump for replacement, it is highly recommended to install a new grommet/filter at the same time. They are inexpensive and will prevent future leaks.

Frequently Asked Questions (FAQ)
Is replacing the washer pump a DIY job?
Yes, this is a very manageable DIY task for most owners. The process involves safely jacking up the front passenger side, removing the wheel and fender liner, and then accessing the pump on the reservoir. The pump pulls straight out and the new one presses in. The entire job typically takes about one hour.
🎬 Watch this step-by-step DIY guide for replacing the F10 pump.Are there any recalls for the M5 washer pump?
There are no specific recalls for the windshield washer pump on the 2012-2020 BMW M5. However, there have been recalls for electric engine water pumps on other BMW models, which are unrelated to the washer system. Always check for recalls using your vehicle's VIN on the NHTSA website.
My M5 has headlight washers. Is it the same pump?
No. If your M5 is equipped with headlight washers, it will have a second, separate pump for that system. The headlight washer pump is a higher-pressure unit and is a different part number. The main windshield washer pump is the more common failure point.

Some F10 M5 owners have reported losing washer fluid over time without any visible leaks. This has been traced to a faulty seal on the washer fluid reservoir cap, which allows the fluid to evaporate due to engine heat. Replacing the inexpensive cap (part number 61667238068) often solves the problem.
