How to Fix the Washer Fluid Level Light on a Subaru WRX
The right way to clear the Washer Fluid Level Light on a Subaru WRX is to fix the underlying cause, not just reset the symbol. Work through the steps below in order — they move from the simplest checks any driver can do to the diagnostic work best left to a scan tool. Following this sequence prevents the classic mistake of replacing expensive parts before ruling out the cheap, common problems first.
- Top up the washer reservoir with screen wash
- Run the washers to confirm operation
- If still lit, inspect the level sensor and connector
- Clean debris from around the float

Is It Safe to Drive With the Washer Fluid Level Light On?
Whether it is safe to keep driving your Subaru WRX with the Washer Fluid Level Light on comes down to urgency (low) and behaviour. As a rule, if the light is red or flashing, or the Subaru WRX is running poorly, stop somewhere safe and arrange help rather than pushing on. If the light is amber and the car drives normally, you generally have time to reach a workshop — but 'have time' is not the same as 'ignore it', so book a check promptly.
Professional Mechanic Tips
If the light stays on with a full tank, tap the reservoir; a stuck float sensor often frees up, otherwise it is a cheap sensor swap.
Use a proper screen-wash mix in a Subaru WRX, not plain water — water freezes in winter and grows algae that blocks the jets.
